Onga IMH750K Intellimaster 0.75kW Variable Speed Domestic Home Pressure Pump with 8L Pressure Tank 

The Onga IMH750K Intellimaster is a compact, energy-efficient variable speed multistage pressure pump designed for domestic water supply, garden irrigation, and light-duty pressure boosting applications. Its intelligent Variable Speed Drive (VSD) technology automatically adjusts motor speed to meet changing water demands, delivering consistent pressure while significantly reducing power consumption compared to traditional fixed-speed pumps. This not only lowers energy bills but also minimises wear and noise for a longer-lasting, quieter pump.

Part of Onga’s ECO SELECT® product line, the IMH750K is one of the most environmentally friendly and resource-efficient pumps available. The durable 304 stainless steel pump body, impellers, and diffuser ensure corrosion resistance and long service life, while the large LCD display allows easy adjustment of the pressure set point and real-time monitoring of performance. Supplied as a complete package with an 8L pressure tank, stainless steel five-way tee, and built-in non-return valve, it’s ready for fast and reliable installation.
