The Honda WH15 is a compact, high-pressure petrol water pump designed for irrigation, sprinkler systems, washdown and general water-transfer applications.

Powered by a reliable Honda GX120 four-stroke petrol engine, the WH15 provides a maximum flow rate of 370 litres per minute, up to 4 bar pressure and a maximum total head of 40 metres. Its combination of pressure, flow and portability makes it suitable for moving water over longer distances or supplying equipment where more pressure is required than a standard transfer pump can provide.

The pump features an aluminium body, BUNA seals, a cast-iron volute and impeller and a durable silicon carbide mechanical seal. A baseplate and integrated carry handle make it easy to transport and position on site.

The Honda WH15 is supplied with port couplings and a suction filter, ready for connection to suitable 1½-inch suction and delivery hoses.

Technical Specifications

Suitable Applications

The Honda WH15 is suitable for:

• Agricultural irrigation
• Horticultural watering
• Sprinkler systems
• Water transfer over longer distances
• Filling and emptying water tanks
• Construction-site water supply
• General washdown work
• Clean and lightly contaminated water
• Pumping water to elevated locations

Understanding Pump Performance

The stated 4 bar maximum pressure is measured at or near zero flow. The actual flow and pressure available at the hose outlet will depend on several factors, including:

• Delivery hose length and internal diameter
• Vertical elevation
• Suction hose arrangement
• Number of bends and restrictions
• Nozzle or sprinkler size
• Condition of the pump and engine

Using correctly sized hose will help minimise pressure loss, particularly over longer distances.

Supplied Equipment

• Honda WH15 petrol water pump
• Baseplate with integrated carry handle
• Inlet and outlet port couplings
• Suction filter

Important Sales and Export Notice

The updated Honda WH15 is approved for sale only within the EU and must not be exported to North America. Please contact Flowjet before ordering if the pump will be used or shipped outside its approved market.

The pump must be filled with water before starting and must never be operated dry. It is intended for fresh water and lightly contaminated water containing suspended particles no larger than 3 mm.
