American APM-56 Series

Close-Coupled Wobble Pumps and Parts

The APM-56 Close-Coupled Wobble Pump offers flows from 0-24 GPM at 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 offering low pulsation and shear of solids in suspension as well as pumping 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. The American pump series is offered in a long-coupled design for mounting on a baseplate with a standard motor.
