  • Robust and durable

    Our High flow rate pumps are powered by our commercial grade GX engine. Equipped with specially-designed professional features, including the ability to deal with silt and sand, they’re perfect for use on construction sites or for clearing floodwater.


    High volume water

    Designed with an abrasion-resistant cast iron volute and impeller, our High flow rate pumps have specially designed vanes for a larger discharge capacity. This means they can move up to 1100 litres a minute – that’s the capacity of an average-sized swimming pool in under an hour and a half.


    Dirty water

    As well as their solid iron parts, our High flow rate water pumps use durable silicon carbide mechanical seals. Both of these features provide extra durability for handling water containing debris up to 6mm in size. There’s even a strainer to ensure nothing bigger gets through.


    Sealed system

    What makes our High flow rate pumps so effective is the craftsmanship of the hose seals and O-rings – 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; they can go for up to 2 hours 50 minutes before you need to add more petrol.


    Tough build

    Our OHV 4-stroke engines won’t let you down. Our water pump engines are reliable and have low emissions – automatic decompression makes them so quick and easy to start. To keep everything in check, they also have Oil Alert™. This prevents engine damage by automatically shutting the unit down if the oil drops below a safe level.

    Frame protection

    Our water pumps’ heavy-duty full frame offers protection to the unit as well as a handy handle for transportation. Anti-vibration straight engine rubber mounts reduce mechanical stress on the unit, so it hums away nicely without juddering or making a racket.
