Justice Series Progressive Cavity Hopper Pumps and Parts

The Liberty Justice Series Open Hopper Progressive Cavity Pump represents an ideal low-flow pumping solution for viscous solutions with high solids contents such as spent grain for the brewery industry with it's ability to pump spent grain or wine must for transfer. The Justice Series offers a design of a heavy-duty auger in a gravity-fed hopper mated to a rotor and stator for the most difficult pumping applications available today.

The LJ8 series of progressive cavity hopper pump parts are supplied as 100% drop in aftermarket replacement parts for your Moyno® J8-Frame and Tarby® TJ8 Frame pumps. Parts such as Rotors, Stators, Connecting Rods, Seals, Gasketery and more are all available as quality aftermarket replacement pump parts for your existing pump assembly.

Flow rates of 11.7 GPM per 100 Revolutions (24 GPM to 51 GPM) at 225 PSI are standard through the range of the series. The modular design of the Justice Series Open Hopper Progressive Cavity pump is a hardened pinned-joint drive assembly with a body available in steel or 316 stainless steel and internal wetted components in either stainless steel or hardened tool steel with hard chrome plating for long-life and durability in abrasive pumping applications.

The large rectangular feed hopper design easily accommodates your pumping medium while the non-pulsating design of the product produces a low-shear flow that conveys your medium along effortlessly. Solids in suspension of up to 50% are accommodated by the Auger design.
