The Shanley SEP Progressive Cavity Pump is an extremely versatile positive displacement pump with a non-pulsating flow that can be used in many different pumping applications. The SEP pump is specially designed for abrasion resistance in tough pumping applications and can pump up to 60% solids. The SEP pump is also ideal for liquids with higher viscosities, or thickness, than water. The gentle pumping action of the SEP pump makes it great for pumping sheer sensitive fluids. The SEP pump is also used for pumping fluids with varying viscosities, for pumping against varying discharge pressures and for pumping applications requiring varying flows using a speed controller. Most commonly used for sludge and polymer at sewage treatment plants, feeding filters and filter presses, centrifuges, feeding oil water separation equipment, food pumping applications like honey, juice concentrate, grapes in wineries, crude oil, viscous chemicals, bilges on ships, coal water slurries and much more.

SEP Features

SEP Design

The Shanley SEP Pump is a progressive cavity pump in 1 and 2 stage design. It’s resilient and tested design is optimal for demanding pumping applications. It’s ruggedized universal joints with wear bushings are sealed and lubricated from the pumped liquid to provide long service life. The SEP pump is available with equal wall stators for lower starting torque and higher discharge pressures.

Pivot Joint Design

The SEP Series pivot joint offers unique advantages while simple in design.

At both ends of the coupling rod, which connects the rotor and drive shaft, are heavy duty pivot points. Each pivot joint consists of coupling rod bushings (inside conical), two yoke bushings and a coupling rod pin. All of these parts are made of hardened steel. A retaining sleeve prevents radial movement of the assembly.

The complete pivot joint assemblies are encapsulated with oil, and sealed by means of an elastomeric cover sleeve which fits into labyrinths at each end of the assembly, and fixed in position by “band-it”® bands.
