The Model 3570 from Cat Pumps is a positive displacement triplex plunger pump that combines high flow and high pressure, rated to 30 gpm and 3,000 psi. It has concentric, high-density, polished solid plungers that provide a true wear surface resulting in long seal life. Oversized crankshaft bearings with greater loading capacity provide long bearing life. V-packings and low-pressure seals are completely lubricated and cooled, reducing stress on seals while increasing service life. The chrome-plated brass discharge manifold is easily serviced without entering the crankcase, reducing field service time. 763/780-5440; www.catpumps.com.
