With a dry weight of 21 kg, the Honda WB20 measures 455 mm (length) x 365 mm (width) x 420 mm (height). Its fuel and oil tank capacities are 2 litres and 0.6 litres respectively. This gives it an operating time of roughly 1 hour 42 minutes before you need to refuel it.
The WB20 has a total head of 32 metres, suction head of 7.5 metres, and 3.2 bar pressure. The inlet/ outlet diameter thread type is 50 mm (2 inches) PF.
Quiet compared to other heavy duty water pumps, it has a guaranteed sound power level of 102 dB(A), with a sound pressure level at the workstation of 88 dB(A).
Serious Professional Capabilities
The Honda WB20 Petrol Water Pump has some serious professional capabilities, including the ability to deal with sand and silt. This makes it one of the best water pumps to use on building sites or for pumping floodwater.
A Durable Water Pump
This dirty water pump features an abrasion resistant cast iron volute and impeller. It also includes specially designed vanes for a greater discharge capacity.
The Honda WB20 uses durable silicon carbide mechanical seals too, which give it the capability to handle water that contains debris up to 6 mm in size. It even comes with a strainer to keep out larger particles.
Exceptionally Reliable Starting
Thanks to its high-quality, commercial-grade Honda engine and automatic decompression, this garden water pump will start reliably, in any conditions, with minimal pull force required.
The Optimised Impeller
This premium professional drain pump is designed with Honda’s uniquely optimised impeller, which includes computational fluid dynamics to minimise energy loss within the pump and increase its pumping performance.
Anti-Vibration System
Honda has added straight engine rubber mounts to this petrol water pump, reducing vibrations and lowering mechanical stress on the machine. This has the result of further extending the water drain pump’s lifespan.
Oil Alert
Designed to prevent damage to the machine, this Honda water pump’s oil alert system shuts down the engine if oil drops below a safe operating level.
The Honda Warranty
Honda is an internationally recognised brand, with an outstanding reputation for producing very high quality machinery. This makes it a name you can trust if you’re buying a commercial water pump.
For your added peace of mind, the Honda WB20 Petrol Water Pump is supplied with an excellent 2-year manufacturer’s warranty for domestic use (or a 1-year warranty when used commercially).
