LJ8 Series

Spent Grains and Wine-Must Open Hopper PC Pump

Justice Series Icon The Justice LJ8 Series Open Hopper Progressive Cavity Pump for spent grains and wine must is a popular choice for the brewery and wine-making industry. 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 Justice Series offers a design of a heavy-duty auger mated to a rotor and stator for the most difficult 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 efficiently. Solids in suspension of up to 50% are accommodated by the Auger design.

The Liberty LJ8 Progressive Cavity Pump parts are direct aftermarket replacements that dimensionally interchange with the Moyno® J8 Series, and the Tarby® TJ8 Series.*

The modular design of the Justice Series offers a hardened pinned-joint drive assembly with a pump body available in steel or 316 stainless steel and with internal wetted components in either stainless steel or hardened tool steel with hard chrome plating for long-life.

Rotors and Stators for the Justice LJ8 Series are available in 1, 2, and 3 stages for applications with 75, 150, and 225 PSI discharge pressures with stators available in Buna Nitrile, Viton, EPDM and Natural Rubber. The standard seal design is a set of packing with a lantern ring and flush connections. Mechanical Seal options are readily available.
