100mm (4”) 316 Stainless Steel Motors – 230V Single Phase

100 mm (4") submersible borehole motors for domestic and small-holding boreholes with a single-phase supply. 6 sizes from 0.37 kW to 2.2 kW, 230 V single-phase, 2-pole 2 900 rpm. They fit any NEMA-standard 100 mm (4") pump end of the same kW.

Motor size100 mm (4")
Power0.37 – 2.2 kW, 2-pole, 2 900 rpm, 50 Hz
Supply230 V single-phase
Startingneeds a 230 V single-phase control box of the same kW (capacitor start)
Construction316 stainless steel, hermetically sealed encapsulated stator
CouplingNEMA standard – fits SVM, SS and other NEMA pump ends
Coolingwater must flow past the motor – fit a flow inducer sleeve if the borehole is much wider than the motor or the pump sits below the water inlet

How to choose: use a motor of the same kW as the pump end, the same size (4" or 6"), and the voltage of your supply. Single-phase motors need the matching control box; three-phase motors need a starter with overload protection.
