Honda WB20 High-Flow Petrol Water Pump
When there’s a large volume of water to shift, the Honda WB20 Petrol Water Pump offers the performance needed to get the job done efficiently. Capable of moving up to 620 litres per minute, it’s a powerful solution for draining flooded areas, transferring water and tackling demanding construction or site work.
The WB20 is driven by Honda’s proven commercial-grade GX 4-stroke engine, delivering reliable performance with easy starting and efficient operation.
Built to cope with tougher pumping conditions, the pump uses an abrasion-resistant cast-iron volute and impeller. This heavy-duty construction makes it capable of handling water containing sand, silt and small particles without compromising durability.
Debris measuring up to 6mm can pass through the system, while the supplied strainer prevents larger objects from entering and potentially damaging the pump.
Long-term reliability is further supported by durable silicon-carbide mechanical seals, while rubber engine mounts help isolate vibration and reduce stress on the machine during extended periods of operation.
For added engine protection, Honda’s Oil Alert technology monitors the oil level and automatically shuts the engine down if it becomes too low.
