Thank you for you interest in our pumps, follow is brief introduction of this prodcut,welcome to contact us for any other technical information or latest price.
1. Brief introduction of City Clean Water Transfering Pump
DG type wearable centrifugal mine water pump is used to transport the clear water and the neutral liquid of pit water with solid grain ≤1.5%. Granularity < 0.5mm. The temperature of the liquid is not over 80oC. The pumps are suitable for water supply and drainage in mines, factories and cities. Note: When the situation is in the coal mine, explosion proof type motor shall be used.
2. Structural characteristics of City Clean Water Transfering Pump
DG series multi stage centrifugal pump is multistage segment type, its suction mouth is located in the water inlet, into the horizontal direction, the outlet of the water in the vertical upward, the head can be used according to the need to increase or decrease the pump series. The pump assembly is good or not, a great impact on the performance, especially the export and import guide wing center, which will make a slight deviation of pump head decreases flow reduction, poor efficiency, so be sure to pay attention in the maintenance assembly. The main parts of D series multi stage centrifugal pump are: inlet section, middle section, outlet section, impeller, guide vane baffle, water outlet guide wing, shaft, sealing ring, balance ring, shaft sleeve, tail cover and bearing body.
