Vacuum priming device for medium and large pumps: replaces foot valves, 0.45–10 m³/min, DN 25–100, simple, standard or fully automatic versions, 12 sizes.
A vacuum priming unit fills large centrifugal pumps before start-up by evacuating the air from the suction line. It replaces the traditional foot valve at the suction inlet, which reduces suction losses and improves the suction performance of the main pump.
Choose the simple, standard or enhanced version depending on the level of automation you need – from manual start to fully automatic priming integrated into the pump-station control.
Twelve sizes cover suction capacities from 0.45 to 10 m³/min and connections from DN 25 to DN 100. For larger volumes we design a dedicated unit.
Water plants, power plants, paper mills, petrochemical sites and any station where large pumps draw from a lower level, as well as applications where a liquid level has to be raised.
Foot valves create suction losses and can leak or jam. A vacuum priming unit avoids both and improves the main pump's NPSH margin.
Typically 5–10 minutes, depending on the suction-line volume.
Flow rate, head or vacuum level, the liquid or gas and its temperature, required materials, motor voltage and frequency, and any standard or ATEX zone. A data sheet or the nameplate of an existing pump is ideal.
