The Cat Pumps Model 56 is ideal for portable trailer-mount and smaller hydroexcavating equipment. At 1,760 rpm, this industrial-grade pump delivers 8 gpm at up to 2,500 psi. It can be hydraulically driven in a direct-drive configuration, and is built around a mechanical drive end to provide reliable long-life service. The discharge manifold is constructed from high-tensile forged brass for high strength and durability. Preset low-pressure seals provide secondary protection against external leaks. Durable dual V-packings are lubricated and cooled by the pumped liquid for long seal life. Concentric, high-density, polished, solid ceramic plungers provide a true wear surface and extended seal life. 763/780-5440; www.catpumps.com.
