1" Gearbox 47 Series Triplex Plunger Pump 

The General Pump TS2021GR is a T Series 47 S triplex plunger pump equipped with a GPZGRS1000 (ZGRS1000) 1" Interpump gearbox.

The nickel plated forged brass manifold offers increased corrosion resistance compared to manifolds without the plating. This pump delivers a maximum flow rate of 4.5 GPM and endures a maximum pressure of 3500 PSI. Extensive engineering and hand-picked materials allow the triplex plunger pump to maximize its lifespan.
