Robust and Rugged

The DryMax is an incredibly robust site pump which can be left to run dry without risking damage. A 5.4 litre fuel tank allows for approximately 6 hours continuous use so once it is in place the DryMax can keep on running.

Handles what other pumps can't

The DryMax is adept at pumping thicker site fluids such as sewage, mud, dirty floodwater and any fluids containing solid particles up to 40mm in diameter.


The integrated two-wheel site trolley with large folding handle allows for easy transportation around site

Hoses also available

The DryMax2 connects to 2" layflat hose out and 2" spiral hose in. The DryMax3 connects to 3" layflat hose out and 3" spiral hose in. These can be purchased as optional extras on the dropwdown menus.
