Cat Pumps presents another new direct-drive Plunger pump for the portable cleaning industry. The 3SP30G1I gas model delivers 3.0 gpm at 3,000 psi while the 3SP35GEI electric model delivers 3.5 gpm at 2,500 psi. Both models are a direct-mount, flange style pump with a new streamline ribbed crankcase. The flange-mount design permits easy mounting to most gas engines or electric motors, increasing flexibility and compactness. Other special features of the 3SP Pump include specially formulated V-Packing Seals, solid ceramic plungers, a shaft key with a set screw and a compact pressure regulating unloader with an adjustment handle, a by-pass hose and a fixed chemical injector.
