ZPH pump is horizontal, multistage, single suction centrifugal pump, it is used for the clean water with no solid particles and the temperature lower than 80℃ or similar physical and chemical properties of liquid water. It is applicable for coal mine, factories and cities water supply and drainage engineering. It is suitable for delivering the clean water with solid particles less than 2% ( particle size not less than 1 mm ), medium solid concentration less than 5%wt, temperature ≤105℃ or the other liquid with similar physical and chemical properties.

A：impeller processing order
The rotating shaft of the coal mine submersible pump is driven by a motor to increase the energy of the liquid, and then the required liquid is continuously passed through the pump’s inlet section, impeller, guide vane, middle section, and horizontal section of the outlet section. Stage inlet section, reverse impeller, reverse guide vane, vertical exit of the outlet section.
Technical advancement of ZPH stainless steel coal mine submersible pump:
Pump adopts the symmetrical arrangement, to basically eliminate the axial force, the residual axial force is born by a back-to-back angular contact ball bearing.
Because there is no balance device, namely there are no various faults, such as no balance plate lose efficacy leading to wear of the pump balancing plate and balancing plate seat balance or rotor bite dead, greatly extend the pump service life.
safe pump body sealing design. Allow the pump single head up to 1.0Mpa(100m),outlet pressure can up to 20Mpa (total head 200m).And prevent the core covering parts composed of bearing and rotor from the influence of the temperature change, with outstanding thermal shock resistance.
- Diving operation, electro-mechanics new drainage equipment, made up of water filled high pressure submersible motor and multistage centrifugal pump, submerged operation (I protection level IP68). Low request of installation environment condition, vertical or horizontal use, can placed in appropriate drainage place According to local conditions.
2.High efficiency, low noise, low temperature rise.
