How to choose

Flow and head, not motor size alone

Flow in GPM tells how much water moves, while head in feet tells how high the pump can lift water. The VEVOR gives 37 GPM and 276 ft, the FLUMEXXON gives 34 GPM and 196 ft, and the Holdwell gives 28 GPM and 167 ft. Compare both figures with the well depth and the water demand, since a high flow with low head will not suit a deep well.

Casing size and discharge size

Casing size decides whether a pump fits the well, and discharge size decides the piping connection. The VEVOR fits 4 inch or larger casings with a 1-1/4 inch NPT discharge, the FLUMEXXON fits 4 inch or larger casings with a 1-1/4 inch FNPT outlet, and the Holdwell fits 4 inch or larger casings with a 1-1/4 inch NPT discharge. The Hallmark gives a 3.8 inch maximum outside diameter with a 1-1/4 inch NPT discharge, so check the casing against the pump diameter before choosing.

Filtration, check valves and protection

Filtration and check valves protect the pump and the water line. The VEVOR, FLUMEXXON and Holdwell each have a filtration mesh or screen, and the VEVOR and Holdwell each have a built-in check valve. The VEVOR motor has built-in overload protection, and the Holdwell motor has built-in overheat protection. For a new drilled well with excess sediment, a layer of gauze at the filtration inlet helps keep impurities out.
