PC Wobble Pumps and Pump Parts

The American series offers the best value available for a Wobble Stator Progressive Cavity Pump for flows up to 53 GPM and pressures up to 150 psi. The simple design of the pump with just one universal joint gives you the inherent advantages of a progressive cavity pump of low pulsation and shear with solids handling of viscous liquids at an affordable price.

AP and APM Wobble Stator Pumps

We offer this pump in both the long-coupled wobble stator pump and close-coupled wobble stator pump versions with designs to meet any application. Both pumps are available with a hard-chrome plated rotor and pump casings in either cast iron or 304 stainless steel with standard Buna Nitrile stator with options in Viton.

In addition, both pumps are available with a standard mechanical seal or can be upgraded to a hard-face mechanical seal for abrasion resistance. We also offer optional gland packing.

The series is offered in a long-coupled design for mounting on a baseplate with a standard motor, or with our unique close-coupled design mounted to a 56C or 145TC "C-Face" motor. All pumps are offered "off the shelf" from our inventory for immediate shipment.
