Velocity for a suction hose on a self priming pump

Velocity for a suction hose on a self priming pump

Velocity for a suction hose on a self priming pump

(OP)
This is a general question understanding that elevation will play a role and actual suction lift, but these types of pumps are diesel driven and end up in a variety of applications.

I have heard everything from 11 f/s to 23 f/s as maximum velocities.

I have attempted to calculate by taking the suction lift, subtract from 33.9 (assuming sea level), and then use Hazen Williams to calculate the flow.  These numbers, however, seem to be high.  Any help is appreciated.

RE: Velocity for a suction hose on a self priming pump

Suction piping on pumps piping should be a maximum velocity of 4 to 6 ft/sec.

If your suction hose is ribbed, you should use less velocity that the above.
