Description

Overview

The 4SD4/21 is a 4-inch stainless steel multistage submersible borehole pump with a 2.2 kW motor rating, a shut-off head of 157 m and a flow of up to 100 L/min. It comes from the Vega 4SD4 range, which has a nominal flow of around 4 m³/h, and it fits boreholes with an internal diameter of 100 mm or more.

On the performance curve it still delivers 50 L/min at 136 m, and 10 L/min at 152 m at the lighter end. It is built for deeper boreholes, long uphill pipe runs and farm supply lines that need real lift behind them.

Key features

Stainless steel pump body and shaft for long life in borehole water
Shut-off head of 157 m, with 50 L/min at 136 m at the middle of the curve
20Y intelligent controller option adds dry-run protection for low-yield boreholes
Pump end sold separately to fit an existing 2.2 kW motor

Where it works

Typical jobs include Free State and North West farms, Western Cape vineyards and KZN estates with deep boreholes and long supply lines. Browse more in our borehole pumps range, or compare the 4SD4/18 borehole pump (1.5 kW) and the 4SD3/62 borehole pump (5.5 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 4SD4/21 option should I buy?

Choose the 220 V set if you only have single-phase power. The analogue box is the basic starter, and the 20Y controller adds dry-run protection, which is worth having on a low-yield borehole. The 380 V set suits three-phase supply and comes with the Y1 controller. If you are replacing a worn pump end on an existing 2.2 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 4SD4/21 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 157 m at shut-off.

How much is delivery to Polokwane?

We deliver to Polokwane in 1 to 3 days. The heaviest option ships at about 31 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.
