FPS SS636 – Stainless Steel Submersible Borehole Pump Ends
The FPS SS636 is a multistage 304 stainless steel submersible borehole pump end (145 mm diameter) for irrigation and larger water schemes. It is designed for 24 – 51 m³/h (400 – 850 l/min) and gives heads from 46 m up to 331 m with motors from 4 kW to 30 kW. Each model is supplied for a 100 mm (4") or a 150 mm (6") motor. This is the pump end only – add a submersible motor of the same kW and a starter or control panel.

How to choose: use the flow your borehole can safely deliver, then pick the SS636 model whose head at that flow covers your total head – pumping water level plus the height to the tank plus pipe friction. The number after the slash is the number of stages. Choose the 4" or 6" motor version to match the motor you have or need. Each product page has the full performance table.
