Find the pump for your well.

Enter your pumping water level, pump setting, pipe and desired pressure.

Well & pressure

Depths are below the wellhead. Pumping water level is the water surface while pumping; pump setting is the intake depth.
Extra pipe, elevation & lossesDefaults are 0: desired pressure is at the wellhead after the drop pipe. Additional pipe uses the same size and type.
Use negative elevation for downhill delivery. Add actual check-valve losses; high-capacity curves exclude a check valve.

How these results are calculated

Estimated intersections of the supplied catalog's pump curves with the system head curve. System head = pumping water level + delivery elevation + 2.31 × (desired PSI + equipment loss PSI) + pipe friction + velocity head. Drop-pipe length equals pump setting depth.

Hazen-Williams friction uses actual inside diameter, C=150 for PVC and C=100 for steel. Existing pipe condition can change losses. GPM is interpolated from the original vector curves and rounded to 0.1 GPM. No extrapolation outside solid curve data or the manufacturer's operating arrows.

“Best efficiency” means within the catalog's shaded flow band, not an efficiency percentage. Points within 0.2 GPM of a band boundary are marked “Near band edge.” Models are stainless pump ends (PE), not complete motor assemblies. See the linked ordering page to select voltage, phase, motor and control.

Coverage: 3200, Series V and Tri-Seal well pumps, 4 and 6 inch, nominal 5–125 GPM. Effluent and cistern pumps are excluded.
