Flush Pumps
Flush pumps are used for low lubricity liquids (Deionized water) and liquids with elevated temperatures. 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.
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
