Sometimes you need a pump that can handle higher pressures, viscosities and torque. Applications like these require the 70300 or 70600 models which feature oversized drive ends. For the 70300 the next larger drive end design is used with a standard 70200 element. The 70600 is customized with a drive end that is 2 times larger with a standard 70200 element. As a result, either model can handle high-pressure spraying, chemical injection into high-pressure lines and applications involving pressures above 225 psi. The 70300 series also allows you to use the standard design, normally rated to 75 psi and 600 RPM, in applications which call for their full element ratings. Standard pumps offered in the 70300 series are three, four, and six-stage pumps.
