American APM-44 Series

Close-Coupled Wobble Pumps and Parts

The APM-44 Close-Coupled Wobble Pump offers flows from 0-15 GPM and 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 with low pulsation and shearas well as solids handling of viscous liquids 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. The American pump series is offered in a long-coupled design for mounting on a baseplate with a standard motor.
