Long-Coupled Wobble Pumps and Parts

The AP-33 long-coupled Progressive Cavity Wobble Pump series from Liberty Process Equipment offers the best value available on the pump market for flows from 0-9.4 GPM and pressures up to 50 psi. The simple design of the wobble stator and just one universal joint give you the advantages of a progressive cavity pump of low pulsation and shear, solids handling and viscous liquid pumping 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.
