The Model 3570 from Cat Pumps is the ideal combination of high-flow and high-pressure, rated to 30 gpm and 3,000 psi. Higher flow rates are desirable to get more work done in less time. Chrome-plated brass manifolds provide added strength and corrosion resistance. Concentric, high-density polished solid plungers provide a true wear surface that results in long seal life. The drive-end uses matched connecting rods and oversized bearings to provide many hours of trouble-free service. 763/780-5440; www.catpumps.com
