Description
Overview
The 4-inch 7.5 kW 380 V borehole motor is an oil-filled submersible motor that turns your pump end from inside the borehole. It is wound for 380 to 415 V three-phase mains and works as a replacement motor for a Vega 4SD or 4ST pump end of the same power rating. The oil-filled body is rated for 20 bar, and the 2 m lead-out cable leaves you room to splice and extend on site. Protect it with a Y1 digital protection controller from our borehole controller range.
Always match motor power and voltage to your pump end and your supply. Not sure what you need? Send us the pump model and we will check it with you.
Key features
- 7.5 kW output on a 380 to 415 V three-phase supply

Where it works
Deeper irrigation boreholes and municipal top-up supply in Gauteng, North West and the Mpumalanga coal belt. The 7.5 kW size is a good match when your pump end calls for exactly this power rating, so check the pump data plate before you order.
Browse the rest of the borehole pumps and motors range, or compare the 5.5 kW 380 V motor and the 7.5 kW 525 V motor.

Questions about this product
Which pump ends does the 7.5 kW 4-inch motor fit?
It fits Vega 4SD and 4ST pump ends of the same 7.5 kW power rating. Always check the data plate on your pump end before ordering, and send us the pump model if you are unsure so we can confirm the match with you.
Do I need a protection controller for this motor?
A protection controller is strongly recommended. A Y1 digital protection controller from our borehole controller range guards the three-phase motor against dry running and overload, which are the usual causes of early motor failure on boreholes.
Do you deliver a 7.5 kW borehole motor to Johannesburg?
Yes. We deliver with our own trucks from Polokwane to Johannesburg, Pietermaritzburg and the rest of the nine provinces in 1 to 3 days. At 24 kg this motor falls in the up to 30 kg delivery band at R550, and orders of R20,000 or more (VAT incl.) are delivered free.
Is the lead cable long enough for my borehole?
The motor comes with a 2 m lead-out cable. That is the motor lead only, so you will need to join it to a suitable supply cable that runs the full depth of the borehole to the surface. Tell us your setting depth and we will advise on the cable.
