Submersible sewage pump flow range of 3-6000m3 / h, head is 7-100m, power is 0.25-315KW. WQ-type submersible sewage pump is one of more used, it is suitable for industrial and mining waste water discharges below 40 ° C, domestic sewage, manure or liquid containing fibers, paper and other non-corrosive solids. Liquid PH value in the range of 5-9, the solid particle diameter of less than 20mm. Is widely used in mine construction, municipal engineering and hospitals, hotels, restaurants sewage debris emissions, can also be used as oil recovery, water treatment and farmland irrigation. WQP stainless steel submersible pumps suitable for corrosive liquids, particularly good medium to determine when to make selection of manufacturers choose a suitable material. QWB-type explosion-proof submersible pump is also based on WQ row of submersible sewage pump above the motor with explosion-proof motor for chemical plants, coal, oil and other requirements of the explosion-proof environment. Figure 6-12 shows the structure of the WQ submersible sewage pump. The suction port is located at the bottom of the pump and the discharge port is set horizontally. Use vertical submersible motor and pump directly connected, overload protection device and water immersion protection device to ensure the safety of operation.
