The General Pump TS1621 is a pump engineered for pressure washing applications and features the preferred frame of the industry. The forged brass manifold is coated with nickel-plating for superior corrosion resistance to increase its longevity. Over-sized connecting rods, solid ceramic plungers, and heavy-duty tapered roller bearings are used because of their increased longevity. Packings are lubricated by the fluid being pumped extending the life of these components by preventing unnecessary wear.
