The Model 3560 high-pressure water pump from Cat Pumps offers up to 20 gpm at 1,200 to 4,000 psi. This triplex pump has preset low-pressure seals that provide secondary protection against external leaks and require no packing adjustment. Special high-density, polished, concentric plungers provide a wear surface that extends seal life. The pump manifold wet-end is easily serviced without entering the pump crankcase. It can be driven by a direct-coupled hydraulic motor. Its oversized crankshaft bearings are designed for high loading capacity. 763/780-5440; www.catpumps.com.
