Submersible water pumps for mining, deep well pump, centrifugal pump, stainless steel pump Model:200QJ20-30/2 Flow: 20m3/h Head: 30m Power: 3kw Material:Cast iron/stainless steel Impeller material:Cast Iron/stainless steel Pressure:Low Pressure Warranty:12 Months Color:Blue Place of Origin: ,China (Mainland) Deep well submersible water pump Overview: deep well submersible water pump is widely used in various kinds of water conservancy facilities such as farm irrigation, sprinkler irrigation with water, the supply and drainage system of civil building and, industrial and draining water from the hills and mountainous area, the diversion in low-lying areas, water supply and drainage in urban and rural industrial and mining enterprises etc. http://www.dragonpump.com/products/qj-deep-well-submersible-pump/ Deep well submersible water pump structure&model meaning 1. Submersible electric pump is composed of five parts: water pump, submersible motor, water line, waterproof cable and control switch. Water pump belongs to single suction multistage vertical centrifugal pump. 2. Submersible motor adopts water-filled wet structure, internal chamber was filled with water for cooling the motor and lubricating the bearing. In the operation, due to the changes of temperature, the pressure of the filled water in the internal chamber also changes, it can be automatically regulated by pressure-regulating unit in the lower part of motor. 3. For preventing the sand getting into the motor, the sand-preventing unit including sand and skeleton oil-sealed was installed in the upper part of motor, the whole motor was sealed tightly. 4. There are water injection hole and exhaust hole in the upper part of the motor and discharge hole in the lower part. 5. There are thrust bearing and thrust collar, mainly for sustaining remnant axial force of pump and the empty weight of motor's rotor. http://www.dragonpump.com/products/qj-deep-well-submersible-pump/ Deep well submersible water pump spare parts &features: Deep well submersible water pump motor and pump assembled into one.

Qj submersible deep well pumps, submersible pumps, multistage submersible pump Product description: Qj submersible pump is directly connected with motor, which applies to groundwater extraction from deep wells. It can also be used in rivers, reservoirs, canals and other water projects. The pump is mainly used for irrigation and the mountain plateau drinking water and also for the cities, factories, railways, mines, construction sites for drainage and water supply. Main features: 1.Motor, pump are put into operation in the water, so the safety and reliability are ensured. 2. There is no special requirement for the materials of the tube and pipe.
