Justice Series

Progressive Cavity Hopper Pumps

The Justice Series Open Hopper Style Progressive Cavity Pumps represent an ideal pumping solution for viscous solutions and those with high solids contents such as sludges and slurry's, wine must, food waste, thickened food slurries, food pulps and other low flow-able pumping mediums that other pumps would have difficulty pumping.

The Justice Series offers a heavy-duty hopper-mounted auger mated to a rotor and stator for the most difficult progressive cavity pumping applications. Our auger feed design forces the liquid and solids toward the rotor and stator so it can fill the cavities and then pump. The heavy-duty hopper has slanted sides so the material to be pumped is gravity-fed towards the auger.

Flow ranges for the Justice Series are from 0-293 GPM with stators available in 1, 2, and 3 stages representing 75, 150, and 225 PSI discharge pressures in materials like Buna Nitrile, Viton, EPDM and Natural Rubber. The standard seal design is a set of gland packing with a lantern ring and flush connections. Mechanical Seal options are readily available.

The modular design of the Justice Series Open Hopper Progressive Cavity Pump is a hardened pinned-joint drive assembly with a suction 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.
