Flow rates
The tables below list the approximate water-flow rate per revolution for the 400D pumpheads. The flow rate
will depend on the duty fluid (viscosity, density etc.), pressure, temperature, speed, tubing and the installation.
For accurate flow rates and repeatability calibrate the pump for your application.
