The SP46-24 (VP48A-24) is a 6" stainless steel multistage submersible borehole pump from the SP46 range (nominal flow around 46 m³/h), delivering heads of up to 322m and flows up to 66 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 36 m³/h (36 000 litres per hour) at 240m head. Best for large-scale irrigation, farms, community and municipal water schemes and mining, where the borehole can deliver high volumes.
Available options:
- 380V set: pump + water-filled motor (no starter): SP46-24 pump end + 37kW 380V three-phase water-filled 6" motor (starter panel not included)
- 525V set: pump + water-filled motor (no starter): SP46-24 pump end + 37kW 525V three-phase water-filled 6" motor (starter panel/VSD not included)
- Pump end only (no motor): SP46-24 pump end (wet end) only – to replace a worn pump end on an existing 37kW 6" motor
- Motor power: 37kW
- Pump diameter: 6" – needs a borehole with an internal diameter of at least 150mm
- Stainless steel pump construction

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.
