An immersion pump non-negative pressure water supply equipment, comprising a water inlet pipe 18, a non-negative pressure steady flow regulator 20, a negative pressure eliminator 6, a negative pressure detector 5, a pressure detection device 11, a pressure stabilizing tank 10, and a control cabinet 4 , the incoming water flows through the water inlet pipe 18, the bypass valve 17, and the direct water outlet check valve 16 to the equipment outlet pipe 15, and the water also flows into the non-negative pressure steady flow regulator 20 through the water inlet valve 13 at the same time. The upper part of the flow regulator is provided with an immersion water pump 7, the motor of the immersion water pump 7 and the water outlet of the immersion water pump 7 are outside the non-negative pressure steady flow regulator 20, and the water-absorbing part is immersed in the non-negative pressure steady flow regulator 20, The outlet of the submerged water pump 7 is connected to the connecting pipe 12 through the check valve 8 and the valve 9, and the other end of the connecting pipe 12 is connected to the outlet pipe 15. A drain valve 19 is provided at the bottom of the pressure stabilizing flow regulator 20 .
