The Model 3550 high-pressure plunger pump from Cat Pumps is rated to 10 gpm at 6,000 psi. It is suited for equipment operating in high-duty cycle applications in remote or mobile applications, such as hydroexcavating, jetting, blasting and hydrostatic testing. It can be direct-driven hydraulically or pulley-driven from a motor or engine. Its V-packings and low-pressure seals are completely lubricated and cooled, increasing service life. Hard-chrome-plated forged brass inlet/discharge block manifolds offer strength and fluid compatibility. The wet end is easily serviced without entering the crankcase. 763/780-5440; www.catpumps.com.
