Mining Dewatering Pumps For Salty Water & Harsh Conditions

Grant Kemp is the Mining – General Foreman for Mining SXO Underground Operations at Minjar Gold Pty Ltd which is part of their Southern Cross Operations. In this interview, he discusses using PumpEng Raptor and MetalVest submersible pumps for their underground mine dewatering where managing water volume and extreme salinity were a challenge.

Large Water Volume

How do you describe your operation?

Salty Water Dewatering Pump For Mining

Ours is a small underground operation with a lot of water issues. There are huge volumes of water we have to pump out from underground.

Old Pumps Not Coping with Capacity

What were the problems you were having with your old pumps?

They couldn’t handle the capacity of the water coming in. Due to the nature of the water, we were always having maintenance issues with them. Since changing over to PumpEng, we get good service.

Service From PumpEng

Why did you decide to try PumpEng pumps?

The contractor we were using was using them. We could see that they were getting a really good service from PumpEng. That is the reason we changed. We actually took over the contract, and the service has been extraordinary. If we strike a large volume of water unexpectedly we can ring them and get pumps to us. They offer a really good service.

How many pumps do you currently have?

I think it’s about 18, a combination of Raptor and MetalVest. These are all used underground for dewatering.

Efficient Turnaround

How would you describe PumpEng customer service?

They offer a great service, in particular the turnaround. Due to the nature of the water here, it’s very harsh. It’s a couple of hundred times saltier than seawater. It is extremely tough on any pumping equipment. For that reason, we need someone who can repair these pumps and turn them around efficiently. That turnaround is exactly the service that we get from PumpEng.

Reliable Pumps

What sort of feedback are you getting from your crew?

The only feedback I hear is about the reliability of the pumps. Very occasionally, we might have to use another supplier.  PumpEng doesn’t have something available. Due to the nature of the conditions and the water we’re pumping, those other pumps just don’t last. That just reinforces that the PumpEng pumps do a good job.
