Testimonial

domeshelter

We have been dealing with Liquimech since they started out, and they have never let us down. With both our companies being Australian owned and operated, our values align perfectly, we pride ourselves in manufacturing high quality Australian Made products. I highly recommend Liquimech and wouldn’t think to go anywhere else, appreciate all you have done and look forward to what is to come!

The standpipe is working well, going good. The pump allows for fast truck fill, all comes down to the size of the pump.
Francis
Director - Doolee Construction
Italia Stone Group Logomark

It’s exceeded our expectations. High quality, we don’t need any counter weights and it’s easy to set up. It’s been in operation for 6 months now with no hassles, we’ve got quite a substantial pump driving water to the standpipe and we haven’t any issues. Overall quality & reliability supplied by Liquimech has been very impressive.

I’ve been dealing with Liquimech for some time now and can’t speak highly enough of what they do. With top-notch service and products, great lead times, and very competitive pricing, they really cover all the bases. I couldn’t recommend Liquimech highly enough for anyone that wants all three sides of good, fast, and cheap.
