Heavy Duty Series
Progressing Cavity Pumps
LJ4 Series Open Hopper Progressive Cavity Pump
The LJ4 Series Open Hopper Progressive Cavity Pump represents an ideal pumping solution for viscous solutions with high solids contents such as high-viscosity chemical transfer of liquids and sludge's in industrial facilities and other low-flowable pumping mediums. The Justice Series offers a design of a heavy-duty auger mated to a rotor and stator for the most difficult pumping applications available today. Flow rates of 2.02 GPM per 100 Revolutions (5 GPM to 9 GPM) at up to 225 PSI are standard through the range of the series.
The LJ4 progressive cavity pump parts are direct aftermarket replacements that dimensionally interchange with the Moyno® J4 Series, and the Tarby® TJ4 Series.*
The large 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.
The modular design of the LJ4 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.
Rotors and Stators for the LJ4 Justice 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.
