American Series AP-22

Long-Coupled Wobble Stator Pumps and Parts

The AP-22 long-coupled Wobble Stator Pump offers flows from 0-4.9 GPM and pressures up to 100 psi. The simple design of the wobble stator and just one universal joint give you the inherent advantages of a progressive cavity pump of low pulsation and shear, solids handling, and viscous liquids pumping capabilities at an affordable price.

In addition, the pump is 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 American pump series is also offered in a close-coupled design for mounting on a baseplate with a standard motor.
