This type of drain pump is mainly used in indoor unit of floor standing air conditioner and ceiling-mounted air conditioner. It can discharge condenser water produced by the evaporator in the process of refrigeration and dehumidification. It can work under two kinds of frequency (50/60 Hz). And it has many advantages: high efficiency, low noise, low libration, light weight, small size and energy saving, etc.The shaded-pole motor drives the centrifugal impeller from the pump part running. The liquid comes from the inlet and goes out of the outlet by the force of centrifugal strength of impeller and atmospheric pressure, and it can be discharged to a certain height.
