Vacuum Pump

Enables suction lift (pulling water from below the pump level) because the vacuum pump evacuates air/air-liquid mix and allows the main pump to draw fluid. For example, suction lifts up to 28 ft (or more in some cases) when using the priming system.

Fully automatic priming/re-priming: Once set up, the system can prime and re-prime without manual intervention.

Handles air/liquid mixtures and some solids: this is useful in dewatering, slurry, dredging or similar messy jobs. 

Environmentally safe priming: The float box plus diaphragm vacuum pump means no water carry-over and reduced contamination risk.

Better hydraulic efficiency thanks to oversize suction design: less friction loss, higher flows.
