SP17-16 (VP18A-16) 6″ Borehole Pump 9.3kW – 176m Max Head

The SP17-16 (VP18A-16) is a 6" stainless steel multistage submersible borehole pump from the SP17 range (nominal flow around 17 m³/h), delivering heads of up to 176m and flows up to 24 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 12 m³/h (12 000 litres per hour) at 156m head. Best for farms, irrigation, game lodges, small community water schemes and large properties with a strong borehole.

Available options:

• 380V set + oil-filled motor + 30Y controller: SP17-16 pump end + 9.2kW 380V three-phase oil-filled 6" motor + 30Y intelligent pump controller
• 380V set + water-filled motor + 30Y controller: SP17-16 pump end + 9.2kW 380V three-phase water-filled 6" motor + 30Y intelligent pump controller
• 525V set: pump + oil-filled motor (no starter): SP17-16 pump end + 9.2kW 525V three-phase oil-filled 6" motor (starter panel/VSD not included)
• Pump end only (no motor): SP17-16 pump end (wet end) only – to replace a worn pump end on an existing 9.3kW 6" motor

• Motor power: 9.3kW
• Pump diameter: 6" – needs a borehole with an internal diameter of at least 150mm
• 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.

Which controller? 380V sets up to 15kW come with the 30Y intelligent pump controller; 18.5–30kW sets come with the heavier 30A controller. 525V sets are supplied without a starter – your electrician must fit a suitable starter panel or VSD. 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.
