The utility model relates to a case type booster pump station, comprising a water inlet main pipe, a regulating water tank, a water outlet pipe, a booster water pump, an electromagnetic valve, an electric contact pressure gage and a control cabinet. The water inlet main pipe is connected with the water outlet pipe through a gate valve and a check valve. A surge tank is installed at the end of the water outlet pipe on which a pressure sensing device is installed. The water inlet pipe and the regulating water tank are connected by an inlet/outlet pipe. The water inlet pipe at the front end of the inlet/outlet pipe is also provided with a current feeding pipe. A by-pass pipe is arranged on a main pipe between the inlet/outlet pipe of the regulating water tank and a main pipe check valve. The by-pass pipe is connected with the booster water pump through the gate valve. The output end of the booster water pump is connected with the water outlet pipe. The regulating water tank is provided with an electromagnetic valve which eliminates negative pressure, the electric contact pressure gage, etc. The case type booster pump station of the utility model not only makes use of excess pressure of municipal tap water pipe network but also avoids negative pressure and does not snatch water and does not affect water supply to nearby water users. The structure of the device is compact and the pipeline is simple and the control is intellectualized.
