Description

Overview

The 4SD3/52 is a 4-inch stainless steel multistage submersible borehole pump with a 4 kW motor rating, a shut-off head of 372 m and a flow of up to 80 L/min. It comes from the Vega 4SD3 range, which has a nominal flow of around 3 m³/h, and it fits boreholes with an internal diameter of 100 mm or more.

On the performance curve it still delivers 40 L/min at 308 m, and 10 L/min at 364 m at the lighter end. It is aimed at very deep boreholes and high-lift supply to distant reservoirs, the kind of job where a light pump simply runs out of head.

Key features

Stainless steel pump body and shaft for long life in borehole water
Shut-off head of 372 m, with 40 L/min at 308 m at the middle of the curve
Y1 digital protection controller supplied with the three-phase sets
Pump end sold separately to fit an existing 4 kW motor

Options

Prices are VAT incl.

380V three-phase set with Y1 controller, R 9,928: pump end, 4 kW 380 V three-phase motor and Y1 protection controller.
525V three-phase set with VSD, R 22,360: pump end, 4 kW 525 V three-phase motor and variable speed drive.
Pump end only, R 2,640: wet end only, to replace a worn pump end on an existing 4 kW motor.

Where it works

Typical jobs include deep Northern Cape and Karoo boreholes, mine water supply and large farms feeding reservoirs far from the pump. Browse more in our borehole pumps range, or compare the 4SD4/10 borehole pump (0.75 kW) and the 4SD4/21 borehole pump (2.2 kW).

To size it, add your water level depth, the height up to your tank and about 10% for pipe friction. The pump head at your flow must beat that total.

Questions about this product

Which 4SD3/52 option should I buy?

Choose the 380 V set if you have three-phase power, with the Y1 digital protection controller included. The 525 V set with VSD suits sites that want variable speed control. If you are replacing a worn pump end on an existing 4 kW motor, buy the pump end only.

Does the price include cable and delivery pipe?

No. The sets cover the pump end, motor and controller only. Submersible cable, rope, delivery pipe and the base plate are not included, so allow for those when you plan the installation. We can help you work out the lengths if you send us your borehole depth.

Will the 4SD3/52 fit my borehole?

Yes, if the internal diameter is 100 mm or more. It is a 4-inch pump. Check the casing size and the water level first, then add the height to your tank and about 10% for friction, and compare that total head with the curve of 372 m at shut-off.

How much is delivery to Pietermaritzburg?

We deliver to Pietermaritzburg from Polokwane in 1 to 3 days. The heaviest option ships at about 54 kg, so it falls in the R950 delivery band. Fees go by total order weight: up to 30 kg R550, 30 to 60 kg R950, 60 to 100 kg R1,450, over 100 kg on quotation. Orders of R20,000 or more ship free.
