AP-56 Progressive Cavity Wobble Stator Pump – American Series

The American AP-56 Series Progressive Cavity Wobble Stator Pump from Liberty Process Equipment offers the best value available on the pump market for a progressive cavity pump for flows up to 24 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 of low pulsation and shear, solids handling and viscous liquids at an affordable price.

The Long-Coupled and Close-Coupled Version is available in either Cast Iron or 316 Stainless Steel with standard Buna Nitrile Stator with options in Viton and EPDM and Stainless Internals with a hard-chrome plated rotor for long service life. 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. All pumps are offered “off the shelf” from our inventory for immediate shipment.
