Bomba de água Metabo HWW 3500/25 G

The Metabo HWW 3500/25 G water pump is designed for drainage, garden irrigation and water supply tasks that require reliable continuous operation. Equipped with a 900 W motor, the pump provides a maximum flow rate of 3500 l/h and generates up to 4.5 bar of pressure, making it suitable for moving large volumes of water over short to moderate distances. The pump features a stainless steel drive shaft for improved corrosion resistance and an IPX4 splash-protection rating that helps protect the unit during typical outdoor and damp-environment use. Its compact footprint with dimensions of 470 mm width, 270 mm depth and 575 mm height allows for straightforward installation and storage.

Advantages

The Metabo HWW 3500/25 G combines a high-power 900 W motor with a robust hydraulic performance that achieves 3500 l/h flow and 4.5 bar maximum pressure, delivering steady throughput for domestic and light-commercial needs. A stainless steel drive shaft increases component longevity in contact with water while the IPX4 rating reduces risk from splashing. The pump’s form factor and moderate weight make handling and positioning easier, and its specification covers a range of common water-moving tasks without the need for specialist auxiliary equipment.

Suitable for

• Garden irrigation and sprinkler supply
• Basement or floor-level drainage of rain or accumulated water
• Domestic water transfer between tanks or cisterns
• Small-scale pressure boosting for outdoor taps and irrigation lines

How to use

Place the pump on a stable, level surface close to the water source and ensure suction and discharge connections are securely attached using compatible hoses or pipes. Connect the electrical supply according to local regulations and the pump’s rating, ensuring the power is switched off while making connections. Prime the pump if required by filling the suction line and pump housing with water to remove air pockets before starting. Start the pump and monitor pressure and flow to confirm correct operation; stop the pump immediately if unusual noise, vibration or overheating occurs and inspect for obstructions or incorrect fittings.

Recommendations

Use filtered or screened water where possible to reduce debris entering the pump and prolong service intervals. Avoid running the pump dry; ensure the suction line remains submerged or primed. For outdoor installations, protect electrical connections from direct exposure to rain and provide stable mounting to minimise vibration. Follow local electrical codes for earthing and circuit protection, and consult the Metabo user manual for maintenance intervals, impeller inspection and replacement procedures.
