EVO Pump & Spearing Services (Saskatchewan)

Roper Gear Pumps are widely recognized as one of the most versatile, toughest pumps in the industry. Occasionally, we run into an application that really tests the limits of our pumps.

One such application is on crude oil tank truck transports in Western Canada, where reliability of the 3648’s is paramount. If the pumps don’t run when required, oil doesn’t flow, and the trucks don’t make money. The pumps are not only required to pump tough liquids like abrasive, sandy crude oil, but handle thin dry liquids such as condensate and water. Also, increased environmental awareness requires that the pumps not leak any fluid while operating. The pumps are used to load and unload tanks many times per day, 7 days a week. Couple that with the frigid winter temperatures of Western Canada and the off-road punishment and you have a perfect storm of extreme internal and external conditions that challenge the operating life of a pump.

The Roper Pump Company Innovation Team took up this challenge and set out to make our standard 3648 crude oil pump even more robust. Using an extremely wear resistant bushing material, coupled with a proprietary shaft treatment, the internal components are designed to last much longer than the standard pump internals. A rugged cartridge triple lip seal was the final piece required to lock down the superior leak resistance that the service demanded.

Roper went looking for a company to put the newly minted 3648 EVO Pump to the test.

A prototype was sent to Spearing Services in Saskatchewan. The Spearing fleet was chosen due to their familiarity with standard Roper pumps, as well as having used other locally produced gear pumps.

According to Director of Maintenance Kerry LaLonde, “The first thing that appealed to me about the EVO pump was the simplicity – nothing to constantly oil or grease like some of the other pumps on the market.” One other big positive was the unique triple lip cartridge seal. Kerry said, “I was skeptical that the seal would hold up through the tough conditions, but it really has performed well throughout the trial."

The typical life expectancy of pumps in this service is one “season” (one year), after which, pumps are evaluated for their ability to be rebuilt or scrapped. Spearing’s EVO prototype was installed on Dec 5, 2016, and put into typical, punishing crude oil service. One year later it was still performing flawlessly and is currently running into season number two with no maintenance required.

Kerry says, “The driver loves this pump – he wouldn’t use anything else now. We haven’t touched it for 1+ years and it continues to run strong.”

Roper 3600 EVO pumps are now available for sale in all popular 3600 sizes and configurations. Besides Western Canadian crude oil, other extreme applications like liquid feed supplements and sugar processing are great candidates for EVO installations. Many EVO pumps are being successfully used in abrasive asphalt related applications as well. Contact your local Roper distributor or the Roper factory for more information.

3600 EVO Pump vs. AOD Pump

Screen Shot 2017-10-20 at 2.28.04 PM.png

One of the most overlooked factors when doing a total cost analysis on pumping systems is energy consumption.

In the case of AOD pumps, most do not consider the high cost of compressed air.

This was evidenced recently by a Roper salesman when visiting a sealcoat manufacturing plant that was pumping an asphalt emulsion sealcoat product. They were using a 2” AOD pump to transfer 60 GPM at 50 PSI of the 1000 SSU, slightly abrasive liquid. The plant ran the pump roughly 8 hrs./day, 50 weeks per year (2,000 hours/year).

The plant manager had some initial misgivings about the high acquisition cost of the 3600 EVO versus a diaphragm pump. However, when shown the energy consumption comparison, the 3600 EVO was a relative bargain after only one year of operation.

To do the calculation we used some (generous) assumptions about the air system. Using 125 PSI plant air with no leaks or losses, and a screw compressor at 92% loading. The equivalent electrical brake horsepower for the AOD pump was 17.5 bhp. Conversely, a 3611EGHBFRV EVO pump running at 545 RPM had a bhp of 3.5. Assuming an industrial electricity rate of 5¢ per kWh, the operator would save over $1,000 per year! And this speaks nothing of the other costs associated with diaphragm pumps such as running air lines, pulsation dampener, air regulator, air dryer, etc.

An even larger cost benefit that a user could capture by running an EVO pump versus an air operated diaphragm pump is derived from greatly reduced downtime and fewer spare parts requirements. In this particular example, the abrasive nature of the liquid resulted in required replacement of the AOD pump wetted parts roughly quarterly. Including downtime, this resulted in a net loss of approximately $1,000 per repair. In this application, the 3600 EVO with its extreme wear resistant bushings and shafts is expected not to require any maintenance within the year. Based on these anticipated cost savings, the plant has now replaced several AOD pumps with the Roper 3600 EVO.

Roper Chocolate Pumps

Historians don’t agree on when chocolate originated.

Conventional wisdom says around 2000 years ago, but some evidence supports production as early as 1400 BC. The Mesoamericans believed chocolate had medicinal or spiritual properties and even used as currency. European explorers brought samples back from the Americas, but one described it as “a bitter drink for pigs.” 

The Spanish quickly figured out that adding honey or sugar produced something entirely different, and by the 1600s chocolate was a mainstay across the continent. In 1828, a Dutch chemist developed powdered chocolate, and in 1847, Joseph Fry changed the world with the first modern chocolate bar.

Roper Chocolate Pumps are specifically designed to handle a wide range of applications in the processing of chocolates. These pumps are used to process chocolate liquor, dark chocolate, and a large range of different sugar solutions.

A few component modifications that make our chocolate pump the premier solution:

  • Iron bearings with large square grooves allow for better circulation of the process fluid to prevent build-up. (Carbon bearings are also available as an option)
  • A lantern ring in the packing prevents air from entering the process stream (through the packing). This modification is to prevent the process fluid from hardening within the pump.
  • To accommodate for extra clearance, we have used undersized gears. Gears are available in hardened iron alloy as a standard or stainless steel as an option.
  • The pump can be jacketed as an option for temperature sensitive processes

Other common options for the Chocolate Pump include*:

  • 0.004”oversize bore bearing
  • PTFE packing
  • Aluminum gaskets (for applications up to 400° F)
  • Lantern ring with lube fitting
  • USDA BUNA relief valve O-ring
  • Square endplate grooves (rotation specific)
  • Lube fittings to all bearings
  • Internally jacketed backplate & faceplate (these options require aluminum or high temp gaskets)

*please contact the Roper Pump factory for a full listing of options available.

Roper Pump Company has been a pioneer in the modern chocolate industry from virtually the start. Our innovative pumping solutions have been a mainstay and we’re proud that a majority of major American chocolate manufacturers depend on our pumps in their production processes.

The Vane Pump Efficiency Myth

In a world of “fake news” it’s definitely harder to figure out what’s real and what isn’t.

Since stretching the truth isn’t limited to politics we thought we’d spend some time separating pump fact from pump fiction.  

Some vane pump manufacturers frequently blitz trade magazines with articles touting their “superior hydraulic efficiency”. Don’t buy it.  Their argument is that since the vanes rub on the case, there isn’t any “slip”. The one thing that they fail to mention though is the relatively high amount of slip that occurs on both ends of the pump between the rotor and side plates. Our helical gear pump has a natural action that pushes the gears against each other and forces one towards the face plate and the other towards the back plate.

This reduces the amount of slip along the sides of the pump. Those of you with old vane pump catalogs will see performance curves that include a slip curve. Several years ago one of the larger manufactures eliminated the slip curves and only provided curves at specific viscosity points and pressures.   The slip is now “built-in” to the actual flow curve and (hopefully for them) invisible. We could do that too but believe it’s more important to provide accurate tools needed to size the pump correctly.  

A few years ago we added 2 new pump sizes to the 3600 family that specifically address flow rates versus the one of the most common 3” vane pumps in the market. Our models 3632 and 3643 simply out-pump this vane pump. (See graph).  On top of that in most cases the 3632 is less expensive than a 3” vane pump and in virtually all cases more forgiving in tough applications.


ROC Pump Upgrade for Low Viscosity Liquids

The versatile Roper ROC series of stainless steel pumps are now available with an optional PEEK (polyether ether ketone) idler gear.

This upgrade allows the units to be used in many low viscosity and/or low lubricity liquid applications. PEEK is a very machinable thermoplastic polymer with excellent mechanical and chemical resistant properties – even at higher temperatures.

The PEEK gear option is recommended for fluids less than 100 SSU and available for all sizes in the ROC product range. Please note only the idler gear is made from PEEK material - the 17-4PH stainless steel ROC drive gear remains unchanged.

Contact Roper Pump Company Application Engineers to verify fluid compatibility and other specifics of the application.

Re-writing the Standard for Brewery Grain-Out Process

XERIC from Roper Pump Company is re-writing standards for brewery reliability and performance.

With its patented, all-metal disk stack stator and precision-machined rotor Xeric eliminates the problem associated with progressing cavity pumps typically used in the grain-out process - the rubber. Xeric’s unequalled ability to run dry without damage sets it apart from any other rotary positive displacement pump in the industry.

Even better, it’s not an issue if our customers don’t currently run a Roper Xeric grain-out pump. We’re now offering Xeric upgrades to some of the most commonly used PC pumps regardless of the original manufacturer.

One of the leading American craft brewers based in Escondido, CA is always striving for the highest standards in safety, quality, and efficiency. In their grain-out process this brewer was replacing the stator on their German made rubber lined pump every 3 months costing tens of thousands of dollars in repair parts, labor, and downtime.

Our German OEM competitor offered multiple “solutions” for the issue including shutdown sensors on the inlet, stator, and discharge. The issue is that this so called solution only slows the process and doesn’t fix anything. If the inlet doesn’t fill, it shuts down the pump. If the stator gets too hot, it shuts down the pump. If the discharge pressure exceeds the pumps ability, it shuts down the pump. Solution? No way.

At Roper Pump Company we actually provide a solution - eliminate the problem (the rubber).

With our Xeric technology there’s no need for faulty sensors that only warn of impending failure. If the inlet doesn’t fill, Xeric can run dry. If the stator gets too hot, Xeric has no rubber to degrade. If the discharge pressure increases, Xeric can deliver 2X’s the pressure efficiency per stage. Solution? Absolutely.

We approached this brewer with our Xeric upgrade solution and industry best 2-year warranty. The value was obvious, and we personally installed the Xeric upgrade in the beginning of February 2017 (Super Bowl Sunday to be exact – being from the Atlanta area we enjoyed not seeing that). Not only did the Xeric upgrade eliminate their 3-month failures and constant sensor driven shutdowns, but the added efficiency immediately reduced grain-out time by a full 15 minutes per batch. The reduction in time saves 2-1/2 hours a day. Over the course of a year this will result in a significant increase in production time.

Happy 160th Birthday Roper Pump Company

2017 marks the 160th anniversary of Roper Pump Company. 

We celebrated 150 in style, but like most others that don’t end in a five or zero this one will probably pass without much fanfare - maybe just a card and start planning a big trip at 175. It’s still a good chance to reflect on how we got here, and more importantly ensure transfer of the Roper legacy to future generations.

We proudly trace our roots to the W.D. Trahern Pump Company of Rockford, IL that was founded in 1857 and purchased by our namesake, George D. Roper, in 1906. 

At the time Roper also owned the massive George D. Roper Corporation that included the largest gas stove factory in the world.  The pump and stove operations were split in 1957 with the latter sold off.  Roper Hydraulics (as it was called then), relocated to our current home of Commerce, Georgia in 1959 and became modern day Roper Pump Company.

Back to the beginning in 1857, when Trahern/Roper was founded James Buchanan was President of the United States and the American Civil War was still four years away.  Edison hadn’t invented the lightbulb yet and the first automobile wouldn’t be sold until almost 60 years later.  One thing that hasn’t changed in 160 years though, the world has neededpumps and Trahern/Roper has delivered.  

Trahern manufactured a line of iron and brass hand pumps that helped transform America; our current innovations do the same for industries here and around the world.  Our earliest literature from the 1800s notes: “The Trahern Iron Pump is the most simple in construction, the easiest working, and most durable pump on the market. These pumps are adapted for the House, Yard, Farm, Barn, or any place else pumps are needed.  Whenever you want a pump for any purpose be sure and get the Trahern Iron Pumps…”.   We could update the grammar and use this statement almost word for word with our products today.  

Over the years, virtually everything in our company has changed along with the world around us. While the products are vaguely similar, the ways they’re bought, sold, and used couldn’t be more different. 

Likewise, the way our pumps are made today vs. 1857 look nothing alike; the first plant didn’t even have electricity while now nearly our entire plant incorporates CNC technology.  We’ve evolved over many decades surviving The Great Depression, multiple recessions, multiple wars, reengineering & other “improvements”, yet still prospered, innovated, and grew.  On first glance, it’s easy to think this longstanding success came from a strong brand legacy and not much more.  

While the Roper Pump brand is most certainly solid, the business world is littered with examples of once equally strong companies/brands who came and went in the past 160 years.  The simple answer to what’s made the brand solid is our people who “bleed Roper red”.  Most companies tout something similar but without question Roper Pump wouldn’t be where we are today without generations of employees who’ve viewed the company as more than just a job.  This manifests itself as genuine pride in workmanship and fierce promotion or defense of the company and brand.  It drives making something that was great to start with even better – over and over.  This started in Rockford, and even with only a handful making the move to Commerce in 1959, the ethos was passed along and took hold.  As one original Rockford to Commerce transplant said, “You either get it or you don’t.”

Some generational transfer of the Roper way has literally been just that.  From the beginning it’s been common for second and third generations of the same families to also be a part of ours.  Most true denizens of Roper Pump either retire or unfortunately pass – way too many way too soon; few who get it actually leave for other jobs and many who do eventually come back.  

As American generations evolved from “Greatest” to “Silent” to “Baby Boom” to “X” and now “Millennial” so have views on careers.  Fewer people graduate now looking for a long-term job and even less want to follow their parents or grandparents professional path.  As long as we ensure newer generations continue to “get it” though there’s no doubt Roper Pump will prosper for another 160 years.

Introducing the 3600 EVO

A new breed of the Roper 3600 pump has just been released. This EVOlution of our iconic 3600 series is engineered to outlast other pumps in the most challenging applications. The 3600 EVO is built with extremely wear resistant internals and designed to handle liquids with high abrasive content like asphalt sealcoat, molasses-based liquid feed supplements, and tar-sand crude oil. The 3600 EVO also handles fluids with low lubricity like condensate and oilfield produced water.

The 3600 EVO is fitted with an ultra-hard bushing material engineered to withstand abrasive wear. The shafts are coated with a proprietary treatment that when used in conjunction with the 3600 EVO bushings provides maximum abrasion resistance. This revolutionary combination also self-provides lubricity for “dry”/low-viscosity liquids. A triple lip cartridge seal is available and incorporates a silicon carbide shaft sleeve to ensure leak-free operation under extreme conditions. To round out the 3600 EVO’s abrasion resistant upgrades high carbon steel gears are also available.

The legendary simplicity, design features and options found in the standard 3600 product line offering are available in the 3600 EVO pump. The footprint and port mounting between standard 3600s and 3600 EVOs are identical. Drive options include bare shaft, close-coupled hydraulic motor drive, and integral Roper gearbox.

Contact your local authorized Roper Pump Company Distributor or our factory to find out how the 3600EVO can solve your toughest pumping application.

What sets us apart?

In the power section industry, we’re always encountering someone who needs a product for a more specific application. Needs range from slower speeds and higher torque to longer or shorter motors depending on the required depth.

At Roper Pump, we don’t try to steer the application to “catalog products” just because it’s easier for us. Custom solutions from Roper Pump are what set us apart and unlike others we don’t require ridiculous tooling charges, massive quantity commitments, or extended development time. Instead, we take great pride in being able to provide custom solutions engineered to fit specific needs in a timely fashion.

We recently had someone request a slower-speed power section, and we engineered the solution, built the tooling, and produced a new part for them in four weeks. We also strive to anticipate the future needs of our customers based on changing market conditions and application demands.  By doing so, we can develop proactive solutions that allow our customers to compete more efficiently in a demanding and dynamic market place.

Xeric Upgrade

Do rubber-lined stators constantly have you down for replacement due to running dry, chunked, debonded, or worn rubber?

If so, then it’s time to take your progressing cavity pump to the next level with the Xeric upgrade.

With its patented, all-metal disk stack stator and precision-machined rotor, Xeric removes the problem associated with the progressing cavity pump: the rubber. Xeric’s ability to run dry without damage sets it apart from any other positive displacement pump in the industry.

It’s not an issue if you don’t currently run a Roper progressing cavity pump. Roper Pump is now offering Xeric upgrades to some of the other most widely used PC pumps. Call and find out how this new innovative product from Roper Pumps can start saving you money today.

A lubricant service company in northwest Wyoming that specializes in high performance grease servicing for large mining equipment. Their customers operate shovels and dump trucks that cost $30M and run for a month straight. The service window of the shovels is brief and strictly scheduled. They have only one shot to get in and out before they start causing downtime that costs the mine tens of thousands per hour.

The conventional rubber PC pumps they had been running took a beating in the cold Wyoming winters. The rubber gets stiff and occasionally the pump runs dry when the cold grease doesn’t flow to the pump. The operators are running multiple pumps and don’t have time to monitor every lubricant tank.

They don’t like to admit it, but every once in a while a valve may not have been opened, starving the pump (aka operator error). That’s why they didn’t want to take any more chances on their pumping equipment. They’ve begun to convert their entire fleet to Roper Xeric pumps.

PC pumps did what this company needed, but Xeric does it better. Getting operators to always open the valves is another story.
