Flow rates
The tables below list the approximate water-flow rate per revolution for the 404D 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.
