Viscous Fluids - Recommended Suction Flow Velocity

Sponsored Links

Avoid high velocities in the suction pipes. Higher velocities increases the pressure loss in the pipe and there may be a chance that the pump start to cavitating. As a rule of thumb the suction velocity in front of a pump should be below:

These values depends a lot of the fluid pumped. More about viscosity and viscosities of different fluids can be read here:
