Wilo Actun FIRST SPU 4” Submersible Pump Ends

This category holds Wilo Actun FIRST SPU4 stainless steel and Noryl 4-inch multistage submersible pump ends (hydraulics only) for 100 mm and larger boreholes. The first number is the nominal flow in m³/h, the second the stage count: more stages give more head at the same flow.

Select the range by the flow your borehole can yield, then the model by total head from the performance table. Each pump end needs a NEMA 4” motor of the listed kW and a matching control box – the 0.37 and 0.55 kW models are also sold as complete kits. Clearance stock: once a model is sold out it is gone.
