QD series submersible electric pump consists of three parts: water pump, seal and motor. The motor is a single (three) phase asynchronous motor. The water pump is a closed impeller located below the motor, and the QD type impeller is located above the motor. Double-end mechanical seals are used between the water pump and the motor, and "O"-shaped oil-resistant rubber seals are used as static seals at the fixed seals. Due to its small size and light weight, this series of electric pumps are especially suitable for underground water pumping in vast rural areas, irrigation and drainage of farmland, garden irrigation and household domestic water.
product advantages:
1. The impeller of the hydraulic part of the machine adopts full-lift design, light-load design, and low heat generation of the motor.
2. The pump shaft in contact with water has been hardened and polished, anti-rust and wear-resistant, and a graphite mechanical seal ring is used. The pump shaft has a long service life and the motor has a low probability of water ingress;
3 High temperature resistant enamelled copper wire, high temperature insulating material and high temperature lead-out wire, wide voltage low temperature and full head design, the insulation level meets the national standard, and is safe to use.
