De-Watering Piston Pump

SAI Reciprocating Type Vacuum Piston Pump (Dewatering pump)

Cost of operation is one of the biggest concerns contractors have regarding their equipment.

The SAI piston pump for well pointing, extremely efficient and packed with user benefits, the SAI pumps are capable of operating for very long periods of time on a small amount of fuel. Plus, the pumps provide high air handling necessary on the toughest well point and sock applications.

The pump and motor are enclosed in the stackable frame, which protects the pump unit on working site. During transport the frames can be loaded 2 pieces above each other. The SAI PUMPS are self-priming, positive displacement piston pumps. Because of its efficient design, the pump is capable of operating with very low energy costs, dramatically reducing operational Costs. The pumps also are environmentally friendly, sporting a double sealing piston rod which prevents any oil from entering the environment.

Applications:

This high efficient pump system is used for well point dewatering, under drain sock dewatering,
Filtered water transfers and remediation and reclamation.
