The Honda WB 20 is a high flow rate water pump. It pumps 600 litres a minute with 3.2 bar of pressure and a 2 hours 50 minutes running time. This is a 2" water pump.

These machines are made to shift the flood. Don't get washed away. For professionals up against it, Honda's high flow rate water pumps have commercial features for moving large amounts of water - fast.

Professional pumps
Water gets everywhere – there’s often no escape. Honda's 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 Honda's 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.

Designed with an abrasion-resistant cast iron volute and impeller, these 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.

Oil alert™
This is a useful function that prevents damage to your engine by automatically shutting the unit down if oil drops below a safe operating level.

OHV 4-stroke engine
Powerful and efficient with trusted reliability – it must be a Honda. You’ll get easy starting in all conditions, with automatic decompression to reduce the pull force required.

Cast iron volute and impeller
The cast-iron volute and impeller give you superior durability for long life performance, even when pumping abrasive silts.

Anti-vibration system
Vibration can contribute to wear and tear on your machine. We’ve added straight engine rubber mounts to reduce mechanical stress on the entire unit.
