Progressive Cavity Pump

Metered Uniform Flow
Continuous pushing action in one direction provides uniform discharge without pulsation. Displacement for each revolution of the rotor is affected slightly by changes in discharge pressure.

Low Internal Velocities
All fluids, including highly volatile as well as viscous materials, are handled with minimum turbulence, agitation or pulsation.

Handles Solids in Suspension
The unit will pump solids or abrasives suspended in liquids. Even mixtures containing high percentages of solids are handled satisfactorily.

Self-Priming
Pumping action starts the instant the pump starts. The Pump is built to self-prime at 28 feet of suction lift.

Positive Displacements
The single rotating part exerts a positive pumping action comparable to that of a piston moving through a cylinder of infinite length. Head developed is independent of speed; capacity is approximately proportional to speed. Slippage is a function of viscosity and pressure and is thus predictable for all operating conditions.

Passes Particles
Particles up to 1 1/8 inches in diameter can be handled by the larger Pumps without difficulty. Should a sharp particle become imbedded in the stator, it is passed over and the following fluid tends to flush it free.
