Description

Overview

This 4kw 525v variable speed drive sets the speed of a 4 kW pump motor by changing the frequency it is fed. It is rated 4 kW (5 HP) on a 525 V three-phase supply and a 6.9 A current rating, and costs R 11,489 including VAT.

A VSD is essentially a frequency inverter. Raise or lower the frequency and the motor speed follows, so the pump delivers the duty the application needs at a given moment instead of running flat out all day.

Pick the drive to suit the motor: the motor’s rated power and supply voltage should sit within the figures on this page. Send us the motor plate details and we will confirm the fit before you order.

Where it works

A drive this size fits a borehole pump or farm pressure set on a Limpopo or North West farm, where it holds steady pressure to a tank or drip line instead of the pump switching on and off. It also suits small workshop and car-wash pumps in Gauteng and the Western Cape. The 525 V rating matches the supply found on many mines and large industrial sites.

Need a different rating? See the full pump controllers and VSDs range, or compare the 4 kW 380 V variable speed drive and the 3 kW 525 V variable speed drive.

Questions about this product

Which motor can a 4 kW 525 V drive run?

It is made for a three-phase pump motor rated up to 4 kW (5 HP) on a 525 V supply, with a full-load current within the 6.9 A rating. Check the motor plate for power, voltage and current before you order. If the motor is bigger than the drive, step up to the next size. Send us the plate details and we will confirm.

Do you deliver a variable speed drive to Mbombela?

Yes. Kamano delivers with its own trucks from Polokwane to all nine provinces in 1 to 3 days, Mbombela included. This drive ships at about 4.8 kg, so it falls in the up to 30 kg (R550) fee band. Orders of R20,000 or more (VAT incl.) are delivered free.

Should I choose the 380 V or 525 V drive?

Match the drive to the supply on your site, not to preference. Standard commercial and farm three-phase is usually 380 V, while many mines and large industrial plants run 525 V. Your electrician can confirm the supply voltage and the motor voltage on the plate. We list both voltages across the range.

What does a variable speed drive do for a pump?

It changes the frequency fed to the motor, so the pump speed rises or falls to give the duty needed at that moment. The pump no longer has to run at full speed all the time, and it can start gradually. The result is steadier operation and less wear compared with running flat out.
