Pump Tips

Suction Lift

Maximum theoretical suction lift for self-priming pumps is 25 feet sea level.

Hose Size

1. Best to use a hose that matches the pump size.

2. Larger suction hose will tend to overload engine but increase capacity.

3. Larger discharge reduces friction loss; no effect on pump.

4. Length of hose depends on vertical rise and hose size-generally limit to 500 ft. or 50 ft. for diaphragm pumps.

Pressure:

1 psi=2.31 of head. A pump that has a maximum head capacity of 100 ft. will develop 43 psi (100'=43.3 psi divided by 2.31)

Based on 10 ft. suction lift; higher suction lift substantially reduces performance.
