DeepFlow SB-750 4" Submersible Borehole Pump

A 4-inch multistage submersible for deep abstraction — wells, boreholes, deep reservoirs and underground tanks. Where water sits more than about 8 m below the pump position, atmospheric pressure will not push it up a suction pipe no matter what you spend. A submersible sits in the water and pushes it up instead.

What it is good at

• Borehole and well abstraction on farms, nurseries and rural holdings.
• Filling header tanks and reservoirs from a deep source.
• Continuous seasonal duty where a surface pump would lose prime.

Important

This pump must stay submerged. Fit dry-run protection — running dry destroys the seals within minutes and is not covered by warranty. Water level dropping below the pump in a dry August is the single most common cause of failure we see.
