Sewage Vacuum Pumpout Systems

With the increasing number of boats using our waterways, pump out service is becoming a necessary customer service. Boat owners and marina owners appreciate our pumps because they are clean, odourless, efficient and easy to use. Waubaushene Pump Out Systems replace outdated rotary and diaphragm pumps that are difficult to prime and jam easily.

Phase A

The cycle tank is evacuated, a rotary vane air pump keeps the vacuum in the range of 24" Hg (mercury). With opening the valve in the suction hose the ambient air pressure (atmosphere) presses the effluent into the cycle tank. The foul air coming out of the tank is pumped directly into the discharge line and into the sewer. No odour!

Electronic level controls, timers, motorized ball valves for the effluent and actuated air valves controlled by the electronic master board make the pump switching from Phase A to Phase B and back to Phase A as necessary. No moving part (except air) is in contact with the effluent.

Phase B

The compression side of the air pump is connected with the cycle tank and pressurizes it. The effluent flows from the cycle tank into the sewer.
