Evac OnlineVac

The Evac OnlineVac is a durable, low-maintenance online vacuum generation unit that macerates sewage and generates the vacuum required for the discharge process.

It features extra-strong bearings, heavy-duty mechanical seals, and an electric motor with an IEC flange connection. The vacuum is generated and sewage pumped by means of a special liquid-ring screw pump, manufactured – along with the pump casings – from high-quality, corrosion-resistant stainless steel. Vacuum generation is controlled via the vacuum sensor and PLC, with easy inspection of the inlet thanks to its transparent cover.

Multiple pumps can be connected to the sewage system. Evac OnlineVac units can be customized according to your specific water treatment needs, and are available in two different capacities (V16 and V26) and as a retrofit version. Our Evac OnlineVac 32 and Evac Online 52 systems comprise two V16 pumps and two V26 pumps respectively.
