Conventional Power Sections

In addition to our Even Layer options, we also offer a broad selection of reliable and durable conventional power sections featuring our proprietary elastomers. A top choice among coiled tubing and directional drilling operators, our standard power sections range from 1-½” to 12-¾” diameter, but we can customize them to meet the newest operating requirements.

In our state-of- the-art lab, we calculate, test, and verify the ideal interference fit between the rotor and stator for each power section design. Each elastomer is designed for stability and resistance to swell in common drilling fluids, and we can help select the best elastomer and rotor/stator fit for the job.


Our goal is to offer a variety of elastomer solutions for the application at hand. 

Harder, less hysteretic elastomers deflect less and create stronger seal lines between the rotor and stator while resisting premature chunking. Softer rubber provides more resilience for higher-solid- content applications. To provide the greatest flexibility, we now offer three unique families of elastomer compounds ranging from those based on economical performance to those developed for the most extreme conditions.   

  •  ERZ-STD™ – our standard NBR elastomer, the economical 70 durometer rubber compound for general purpose jobs up to 315°F (circulating fluid temp)
  •  ERZ-HP™– is a 85 Durometer elastomer delivers the most power and strength at temperatures up to 350°F with superior fluid compatibility it is the industry standard for Directional Drilling power sections.
  •  ER2-HP™ – is a hard rubber compound with exceptional rubber-to- metal bonding and thousands of runs in the coiled tubing industry. Ideal for water-based drilling fluids, its superior mechanical strength has allowed many users to execute multiple nitrogen runs without relining. Our most proven compound with thousands of stators in the field and multiple runs on each stator, it is a workhorse in clean fluids and nitrogen up to 375°F (circulating temp).
