Overview
The General Pump TSF2021 is a hi-flow, belt-drive plunger pump rated 8.5 GPM at 3600 PSI running 1750 RPM (7.0 GPM at 1450 RPM). It's built for continuous-duty work — the slower belt-drive pump speed, large-capacity oil-bath crankcase, and heavy-duty tapered roller bearings are what let it run all day on commercial pressure washer and jetter skids. The forged brass manifold carries General Pump's exclusive lifetime warranty, and solid ceramic plungers with lubricated packings handle the wear side. It mounts on a .945 in. (24 mm) shaft with a 1/2 in. inlet and 3/8 in. discharge, and is rated for fluid up to 165°F. Plan on an unloader plus a secondary safety relief valve — both are required on this pump.
