Flushed Manifold Pumps

Flushed Manifold Pumps

Industrial Duty Flushed Manifold Pumps for Low Lubricity and High Temperature Applications


Model 1051C Flush Pump

 

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).
 

Benefits of flushed manifold pumps include:

  • Greatly increases seal life when used with low lubricity fluids such as deionized (Di) water
  • Cools seals, which extends seal life in applications with elevated pumped liquid temperatures
  • Reduces thermal load on ceramic plungers, reducing likelihood of cracking or pitting
