Flush Pumps
Industrial Duty Flushed Manifold Pumps for Low Lubricity and High Temperature Applications
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. Cat pumps flush-style pump models are indicated with the letter “C” or “K” at the end of the model number (i.e., 781K).
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
