It features extra-strong bearings and heavy-duty mechanical seals and features an electric motor with an IEC flange connection. The pump and piping is made from high quality corrosion resistant stainless steel and features a transparent window on the inlet for condition monitoring. 

In a system with an Evac EasyVac unit, vacuum generation is controlled by a vacuum sensor and the PLC. Pumps can be combined from a single V16 up to three V26 pumps for a wide range of vacuum capacities, voltages available from 24V DC (f.ex. photovoltaic installations) to 690V 60Hz AC
