Mining flameproof submersible sand pump Introduction:
Especially suitable for the coal mine roadway and mining working face and other working environment containing methane or coal dust in the sites with explosive air mixture, the discharge of groundwater and water content have suspended pulverized coal and rock debris, the coal grain, sand, silt and solid particles and water.
Unit can dry face surface of shallow water, also can work into the water for a long time. Light and small electric pump compact structure, easy to move, without water, double sealed, durable, safe and reliable, wide applicability etc.

Mining flameproof submersible sand pump Structural features:
1 BQS trapping by the mining flameproof submersible electric pump structure, the upper part of motor, the central for mechanical seal, lower for the pump. Motor and pump mechanical seal and coaxial connection.
2 Electric pump impeller, volute, inlet section, outlet and other parts, impeller fixed by the nut fastening
3 For the three-phase ac motor flameproof dry-type squirrel-cage asynchronous motor. Stator winding use polyester, make motor life is greatly improved.
4 Cable adopts special seal structure, the water could not enter inside motor, adopt and double mechanical seal mechanical seal. In a sealed motor shaft, sealing indoor 15 or 20 machine oil filling, forbid to fill, should take a certain space, in order to avoid motor running fever, machine oil expansion seal damage.
