Professional pumps

Water gets everywhere – there’s often no escape. Our powerful High flow rate pumps are designed to deal with large volumes of it: problem quickly solved.

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.

Water in its vanes

Specially made to process lots more water.

The strainer ensures only debris 6mm and smaller passes through the machine.

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.

A sealed system

An effective pump must create a partial vacuum.

'Total head' (A) is the maximum height the pump can lift water – from the suction head (B) to to discharge head (C).

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.

Pushing power

Also known as ‘total head’, it’s the maximum height the pump can force water suction head to discharge head. Our High flow rate pumps can push it up to 32m – that’s around the length of three buses parked end to end.

The silicon carbide mechanical seal (A), specially-engineered impeller and volute clearance (B), as well as sealed aluminium casing (C), ensure a proper vacuum. This all helps maintain top performance.

Tough build

Come rain or shine, our OHV 4-stroke engines won’t let you down. But especially come rain.

As you’d expect from a Honda, 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.

Low vibration

Rubber mounts reduce stress on the machine.

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.

Machines that last

In 1958, we made the Super Cub – the best selling bike ever made.

The reason for its popularity? It was one of the most economical and dependable bikes around. But Mr. Honda wasn't finished there. Not by a long way. And so nowadays Honda's heritage of engineering is put to good use in lots of other things – lawn mowers, generators, and water pumps.

Not reliable = not useful

We've used our experience in building dependable motor vehicles to design our water pumps. They're built to handle some of the toughest conditions out there, and they're very good at it. But their performance is nothing without the reliability that sits snugly at their core. It's what makes a Honda, a Honda.

A watertight warranty

Like our water pumps, a Honda warranty is the best you can get.

We work constantly to make the most reliable and effective water pumps out there. They’re driven by powerful and efficient 4-stroke engines, and with mechanical seals and cast iron volutes and impellers, they’re built to last.

Made to match

Our water pumps just keep on going. That’s why we can offer one of the most comprehensive warranties out there, too. It maintains the same value throughout the warranty period – meaning the last day of cover is exactly the same as the first.
