Frequently Asked Questions


Why does Shotcrete fibre cause so many problems in pumps?

Shotcrete fibre is a major cause of submersible pump failures underground. Once the fibres are trapped inside your pump, they wear away the urethane and the fibres are forced towards the mechanical seal area and internal casing for failures.

Why is metal better than polyurethane?

A full metal pump is more resilient to the wear from Shotcrete fibres and coarse fines which tear urethane parts to pieces. The JetGuard®, full metal pump has no urethane parts and we expect will save you 40% in repair costs.

How does the hydraulic curtain work on the JetGuard® pump?

The hydraulic curtain is operated by reusing the water already existing in the sump. It is pressurised within the pump and then fanned out on the outside causing a wave of pressure on the surface of the water and under water.

Does reducing the pressure on the mechanical seal area really make a difference?

Yes, reducing the pressure around the mechanical seal area reduces failures.


Is the performance of the Raptor® the same as other brands?

Yes, when comparing performance curves, the Raptor® pump curve is the same, and has the advantage of holding the curve for a longer period due to its lower wear rates.

Are the Raptor® parts interchangeable with other brands?

Yes, the Raptor® parts are 100% interchangeable with other brands. Some parts have been improved to increase reliability and longevity of parts which increases the life and effectiveness of the pump.

What size cable can I fit to the pump?

Most cable sizes can be fitted to our Raptor® from 2.5mm up to 241.1 cable.


What servicing schedule can I sign up for?

We can tailor make any servicing schedule to suit your site and reporting needs, from a low cost direct supply to site to a full priority capped service program.

How do I know I won’t be over serviced?

We guarantee not to over service you by capping your repair cost.

Does PumpEng® service and repair other submersible pump brands?
