The Multi HWA / INOX multi-stage surface pumps are designed for the water supply of single- and multi-family houses, as well as farms. They are also used on recreational plots of land and in gardens. The pumps are self-priming pumps designed for pumping clean and cold water. The pump is available with a choice of NORYL (HWA MODEL) or stainless steel INOX (HWA/INOX MODEL) impellers. We also recommend the Multi INOX pump.

HWA pumps have been in production for 20 years. They are among the most popular models in Omnigena's product range. They are known for their versatility, which opens the way to a variety of applications. To date, they have been used in single and multi-family homes, gardens and in agri-tourism, agriculture or process applications. For 2023, the pumps have been given a new - refreshed - design. The new stainless steel housing is significantly slimmer. In addition, the impellers and diffusers have been modernised. All components are made of the highest quality components. The changes have resulted in increased motor power, increased overall pump efficiency and improved hydraulic performance. The pump continues to have very low noise emissions - only 75 dB.  From 2023 onwards, all models are also fitted with solid brass filling plugs.
