Also known as ‘total head’, it’s the maximum height the pump can force water suction head to discharge head. The WT20 can push it up to 30m – that’s around the length of three buses parked end to end.

Stomach of Iron

The ultimate choice for contractors, farmers, or rental, our trash pumps have been specially designed to take on the most demanding jobs. They allow gravel and other debris to flow through the pump without clogging or causing damage – all whilst pushing out professional water pumping performance. So there’s no need to worry about the water quality – just about getting the job done.

A Sealed System
A Sealed System
What makes our trash pumps so effective is the craftsmanship of their seals – they ensure air can't be drawn in, which causes the all-important vacuum to be lost. The impeller-to-volute clearance has also been designed in this way. It all means they not only have an impressive flow rate and pressure – but they can keep it up; the WT20 can go for up to 2 and a half hours before you need to add more petrol.

Maintaining Your Trash Pump is Easy

Dealing with tough water conditions, occasionally our trash pumps may become clogged – it can happen from time to time. To solve this problem, we designed a removable inspection cover that makes clearing debris quick and simple. If the pump becomes blocked, simply use the provided tool to loosen the quick-release bolts, and lift open the inspection cover to remove any debris. Once it’s done, it’s back to work.
