Professional High-Flow Water Pump
The Honda WB 20 is a robust and durable water pump specifically designed to handle large volumes of water, making it an essential tool for professionals. Whether dealing with floodwater clearance or managing water on construction sites, its high flow rate ensures the job is completed quickly and effectively. Powered by Honda’s renowned commercial-grade GX120 engine, this pump is built for reliability and tough working conditions.
Engineered for Durability and Performance
At the heart of the WB 20 is the powerful and efficient Honda GX120 4-stroke OHV engine. It features an automatic decompression system, which reduces the pull force required for starting, ensuring it’s easy to get running in any conditions. To protect this vital component, the pump is equipped with Honda’s Oil Alert™ system, which automatically shuts down the unit if the oil level drops below a safe operating threshold, preventing engine damage.
The pump’s construction is tailored for longevity, even when pumping abrasive materials. It features an abrasion-resistant cast iron volute and impeller, along with durable silicon carbide mechanical seals. This combination provides superior durability, allowing the pump to handle water containing silt, sand, and debris up to 6mm in size. A strainer is also included to prevent larger objects from entering the pump. The entire unit is mounted on straight engine rubber mounts to reduce vibration, minimising mechanical stress and wear.
Please note, a suitable hosepipe is not included and must be acquired separately.
