CAT Flush Pumps

Product Description

Like all standard plunger pumps, a flushed manifold pump is configured with an inlet and outlet port. However, on a flushed manifold pump, the manifold is also designed with an inlet and outlet flushing port to circulate liquid between the high pressure and low pressure seals to extend seal life and reduce pump maintenance. Cat Pumps offers a broad performance range of flushed manifold pumps from 3.0 to 240.0 gpm (15 to 908 lpm) and up to 10,000 psi (689 bar).
