10SP135/4A 10″ Borehole Pump 37kW – 110m Max Head

The 10SP135/4A is a 10" stainless steel multistage submersible borehole pump from the 10SP135 range (nominal flow around 135 m³/h), delivering heads of up to 110m and flows up to 180 m³/h. It runs on a three-phase supply (380V or 525V). Choose a complete set, or just the pump end if you are replacing a worn one.

At a glance: delivers about 90 m³/h (90 000 litres per hour) at 89m head. Best for large irrigation schemes, municipal water supply and mine dewatering from high-yield boreholes.

Available options:

• 380V set: pump + water-filled motor (no starter): 10SP135/4A pump end + 45kW 380V three-phase water-filled 8" motor (starter panel not included)
• 525V set: pump + water-filled motor (no starter): 10SP135/4A pump end + 45kW 525V three-phase water-filled 8" motor (starter panel/VSD not included)
• Pump end only (no motor): 10SP135/4A pump end (wet end) only – to replace a worn pump end on an existing 37kW 8" motor

• Motor power: 37kW
• Pump diameter: 10" – needs a borehole with an internal diameter of at least 250mm
• Motor size: 8" motor
• Stainless steel pump construction

Performance Table:

Choosing the right pump: add the depth to your borehole’s pumping water level, the height up to your tank or reservoir and about 10% for pipe friction – that’s your total head. Pick a pump whose head at the flow you need is higher than that total. Your borehole must also be able to deliver that flow – ask your driller for the yield-test result, otherwise the pump can run the borehole dry. Not sure which pump fits? Send us your borehole depth, water level, yield and how far/high you need to pump and we’ll recommend the right model before you order.

Oil-filled or water-filled motor? Both drive the pump in the same way. Oil-filled motors are sealed units (rated 25 bar). Water-filled motors (rated 35 bar) can usually be rewound if they burn out, which normally makes repairs cheaper on bigger motors.

Starter / controller: motors above 30kW need a soft starter, star-delta panel or VSD sized by your electrician – these are not included. Ask us for a quote on the complete installation. See all Borehole Controllers.

Not included: submersible cable, rope, delivery pipe and base plate. Large borehole pumps are often supplied to order – contact us to confirm stock and delivery time.
