American AP-67 Series

Long-Coupled Wobble Pumps and Parts

The AP-67 Long-Coupled Wobble Pump offers medium flows from 0-53 GPM and operating pressures up to 50 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 pumping of viscous liquids.

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.
