Red Rhino RGP25-4 1" Petrol Water Pump - 4-Stroke

The Red Rhino RGP25-4 is a 1" self-priming petrol water pump fitted with a 4-stroke engine for smoother, more fuel-efficient running than a 2-stroke equivalent. It is suitable for homeowners, smallholders and contractors who need portable water transfer with a 20m maximum head, making it a practical choice for irrigation and general water transfer where mains power is not available.

• Application: Suitable for garden irrigation, water transfer and general-purpose pumping away from mains power.
• Key specification: 20m max head, 7m max suction depth.
• Connection size: 25mm (1") inlet and outlet.
• Engine: 4-stroke petrol — no fuel/oil mixing required.

Key Features

• 4-stroke engine: Runs on straight petrol (no oil mix), with generally lower noise and emissions than a 2-stroke.
• Self-priming design: Draws water up from below pump level once primed, provided the suction line is sealed.
• Recoil start: Starts by pull cord — no battery or electrical connection required.
• Compact 25mm ports: Compatible with standard 1" hose and camlock fittings.

Typical Applications

• Garden and smallholding irrigation
• Transferring water between tanks or from a dam/river to a tank
• General water transfer where electricity is not available
• Light dewatering of low-lying areas

Installation & Compatibility Notes

Suitable for clean to moderately clean water only — grit and debris can damage the impeller and seals. Suction and delivery hoses, camlock fittings, foot valve and fuel are not included and must be sized to match the 25mm ports. Confirm your required flow rate and head against the 20m max head and 7m max suction before ordering. Check the engine oil level before first use, as most 4-stroke engines are shipped without oil.
