The Model 3570 from Cat Pumps is rated to 30 gpm and 3,000 psi, a combination of high flow and high pressure that is a fit for hydroexcavating, jetting, hydrostatic testing and high-pressure cleaning. It is designed for demanding applications requiring dependable intermittent duty-cycle performance. It includes concentric, high-density polished solid plungers that provide a true wear surface and long seal life. The drive end consists of matched connecting rods and oversized bearings to provide thousands of hours of trouble-free service. V-packings and low-pressure seals are completely lubricated and cooled, increasing service life. The high-pressure manifold is easily serviced without entering the crankcase, reducing field service time. 763/780-5440; www.catpumps.com.
