A sewage pump is used to transfer sewage liquids and solids from one place to another. Usually, in residential applications, sewage includes soft solids up to 2″ in diameter is pumped from a sewage basin to a sewer system or a septic tank. A sewage pump is installed at the lowest point of the sewage basin. Since the pump is submerged most of the time, it is also referred to as a submersible sewage pump. Sewage pump can be automatic, manual or dual mode. A dual mode pump contains a piggyback plug, which allows the pump to be used as either manual, wherein the pump bypasses the switch and is plugged in directly into the socket or as automatic, wherein the pump is plugged in through the floating switch and works only when the switch is activated. Due to a possibility of sewage overflow, it is generally not advised to use a manual sewage pump inside of a sewage basin. Sewage pumps are centrifugal pumps, with special design enabling solids to pass without clogging the pump. When the pump is turned on, the motor starts to rotate the impeller, creating the pressure that pushes water into the impeller and goes into the discharge pipe. The sewage pump is powered through a 10-25 ft. electric cord. Depending on the model, the voltage can be 115, 230, 460, or 575 volts. The pump housing, which contains a motor and an impeller, is made with cast iron and is built for long term use. Want to know more about drainage pumps Vietnam.
