Light Oil Suction Flow Velocity

Recommended suction flow velocity when pumping light oils

Capacity problems, cavitation and higher power consumption in pumps, are often the result of conditions on the suction sides of the pumps.

In general - as a rule of thumb - for light oils, keep the suction fluid flow speed below the following values:

Pipe boreLight Oil Velocity
inchesmmm/sft/s
1 25 0.5 1.5
2 50 0.5 1.5
3 75 0.5 1.6
4 100 0.55 1.8
6 150 0.6 2
8 200 0.7 2.3
10 250 0.9 3
12 300 0.9 3
