The pneumatic ejector pumps have been created with special They can do so in a wide range of capacities and delivery Pneumatic ejectors’ĭesigns allow smooth pumping of municipal waste in a pressure sewage system, Itĭoes not require any constant operation by technicians. Grinder and chopper pumps: These pumps are used in apartments or residential homes which often require low-pressure sewer system pump stations.Įjectors Over Other Types Of Sewage PumpsĪ pneumatic ejector pump is complete and fully automated.Vertical turbine pumps: Used in wastewater treatment plants where the controller and motor are located above-ground.Variations include built together, shaft driven and close coupled. Dry pit pumps: Unlike submersible pumps, dry pit pumps are located in below-ground dry environments.This became popular in the early 1960s, when a guide rail system was developed to lift the submersible pump out of the pump station for repair, and ended the dirty and sometimes dangerous task of sending people into the sewage or wet pit. Submersible pumps: These pumps are submerged in wastewater and they are mostly used in lift stations. Small-scale sewage pumping is normally done by a submersible pump.Split case pumps: Used in booster and water treatment stations.These pumps are best applied in lift stations to prevent solid materials from clogging the sewer system.Īpart from pneumatic ejector pumps, there are other types of

To ensure that the pneumatic ejector in your pump works effectively, you need to perform routine repairs and maintenance to avoid spillage. Pneumatic ejectors using either mechanical or electrical control systems. Is designed to operate with a one-minute cycle consisting of two phases, i.e.įilling the tank and discharging the contents. The sewage ejection function is initiated by a float whichĪscends when the fluid level in the tank rises to a certain level. This pumping mechanism is unique because no mechanical parts Sewage reaches a predetermined level in the tank, the contents are ejected byĬompressed air. Pneumatic ejector pump includes a tank for holding fluid sewage. Ejectors are extremely simple yet reliable mechanisms.
