The Cat Pumps Model 3560 is a high-pressure water pump with two performance ratings to meet application needs: 25 gpm to 3,000 psi and 20 gpm to 4,000 psi. It is ideal for equipment operating in high-duty cycle/remote applications, such as jetting and hydroexcavating. It can be direct-driven hydraulically or pulley driven from motor or engine. V-packings and low-pressure seals are completely lubricated and cooled, increasing pump life. No external oilers are required. The wet end is easily serviced without entering the crankcase. Its 316 stainless steel discharge manifold is optimal for pressure fluctuations in jetting and other high-duty cycle applications. 763/780-5440; www.catpumps.com.
