DESCRIPTION

A professional water pump that has a high flow rate, especially designed to deal with large volumes of water.

Water has a habit of getting everywhere — and when it does, you need equipment that can deal with it fast. Our high-flow pumps are specifically engineered to handle large volumes quickly, helping you resolve flooding, drainage, or site water issues with minimal downtime.

Robust, durable, and powered by a commercial-grade GX engine, these pumps are designed for demanding environments. With the ability to handle silt and sand, they’re ideal for construction sites, floodwater removal, and other heavy-duty applications.

Engineered for Heavy-Duty Performance

Built with an abrasion-resistant cast-iron volute and impeller, these pumps feature specially designed vanes that maximise discharge capacity. The result is exceptional pumping performance — moving up to 1,100 litres per minute. That’s roughly the volume of an average swimming pool cleared in under an hour and a half.

Durability is further enhanced with silicon carbide mechanical seals and solid iron components, allowing the pump to safely process water containing debris up to 6mm in size. A built-in strainer provides extra protection by preventing larger materials from entering the system.

Please note: Hosepipe not included.

Key Features

Oil Alert System
Protects the engine by automatically shutting the unit down if oil levels drop below a safe operating level.

Cast Iron Volute Impeller
Heavy-duty construction provides outstanding durability and long service life, even when pumping abrasive or sediment-laden water.

OHV 4-Stroke Engine
Delivers reliable, fuel-efficient performance with easy starting in all conditions thanks to automatic decompression. Powered by a commercial-grade Honda GX engine.

Anti-Vibration System
Straight engine rubber mounts reduce vibration, helping minimise mechanical stress and extending the overall lifespan of the unit.
