Welcome to Liberty Process

Leader in Progressive Cavity Pumps

For over 25 years, Liberty Process Equipment has been the leader in the field of economically priced Progressive Cavity Pumps and Progressive Cavity Pump replacement parts in North America.

Liberty specializes in Progressive Cavity Pumps for industry. The progressive cavity pump is a positive displacement system that is extremely flexible in its usability in a variety of specialized fields with difficult pumping applications such as viscous and highly-abrasive media. The design offers a pulsation-free, self priming operation that allows solids contents up to 50% to be moved without shearing.

When it comes to moving fluids with suspended solids content such as sludge's or biosolids or thickened abrasives such as grouts or slurries, the PC Pump is the best choice for your application. Liberty can supply both the multiphase progressive cavity pumps and replacement parts to keep your PC Pump operating optimally for a lower price than other suppliers and OEM's and can even offer you full pump packages with motors and baseplates if your job requires it.

We offer same-day shipment with our 24-Hour emergency service and are TSA (Transportation Safety Authority) approved and can ship anywhere from Chicago's O-Hare Airport. Our goal is to meet your requirements and for you to have little or no downtime.
