Metabo HWW 4000/25 Inox Garden Pump (600982000) – 1100 W, 4000 l/h, Stainless Steel

The Metabo HWW 4000/25 Inox is a robust domestic waterworks unit engineered for reliable automatic water supply in and around the home. Its powerful 1100 W induction motor delivers a maximum flow rate of 4000 litres per hour, efficiently drawing water from wells, cisterns, or tanks and boosting pressure for garden irrigation, domestic use, or rainwater harvesting. The stainless steel pump casing and drive shaft ensure long-term corrosion resistance and durability, making it ideal for continuous operation in demanding environments.

Advantages

This pump features a 24-litre stainless steel pressure tank that reduces pump cycling and maintains consistent water pressure. The automatic pressure switch starts and stops the pump based on demand, saving energy and extending service life. With a maximum delivery head of 48 metres and a maximum pressure of 4.8 bar, it can supply water to higher floors or distant outlets. The IPX4 splash-proof rating and 1.5-metre power cable offer flexible installation options, while the 1-inch internal threads on both suction and pressure connections simplify plumbing.

Suitable for

• Automatic domestic water supply from wells, cisterns, or rainwater tanks
• Garden irrigation and lawn sprinkler systems

Recommendations

For optimal performance, install the pump on a stable, vibration-damped surface and ensure the suction line is airtight and fitted with a foot valve. Regularly check the pre-charge pressure in the tank and protect the unit from frost. Use a suction hose with a minimum diameter of 1 inch and keep the suction height below 8 metres for best results.
