Overview
The TSP1821 is a General Pump heavy-duty belt-drive pressure washer pump rated 5.5 GPM at 1450 RPM with a 5100 PSI maximum discharge pressure. Turning at a slow 1450 RPM, it's built for continuous-duty work: a forged brass manifold backed by General Pump's lifetime warranty, a large-capacity anodized aluminum oil-bath crankcase, over-sized connecting rods, tapered roller bearings, and solid ceramic plungers with lubricated packings. Ports are 1/2-inch inlet and 3/8-inch discharge on a .945 in. (24 mm) shaft, with a 165°F maximum fluid temperature. It's the right replacement for belt-drive machines where long pump life matters. Note: every installation requires a primary regulating device (unloader) plus a secondary safety relief valve.
