Submersible Dredge Pump

1.The power supply is 50Hz/380V three-phase alternating-current.
2.The temperature of the medium cannot exceed 60, and the medium does not contain inflammable or explosive gases.
3.The maximum concentration of the solid particles is 30%,max density is 1200kg/m3.
4.The submerged depth of the unit is not more than 20 meters, and the minimum submerged depth takes submerging of the motor as reference.

5.The unit works in the medium vertically, and the working status is continuous.

Use Conditions

NSQ submersible dredge pump is hydraulic machinery, the motor and the pump of which are coaxially working submerged in medium . The wetted parts of the pump are made of high chromium wearable alloy , so the pump has good wear resistance and large flowing passage. It is applicable for conveying media such as sludge, ore slurry, coal slurry, sandstones containing big solid particles. The product is designed and manufactured by domestic and oversea advanced technologies. Besides the main impeller, the bottom of the pump is additionally provided with a set of agitation impeller which can spray the deposited sludge into turbulent flow, and therefore the pump realizes high-concentration conveying under the condition of no auxiliary device. The unique seal device can effectively balance the pressure inside and outside the oil chamber, so as to protect the reliability of the mechanical seal to the maximum extent. The motor adopts various protective measures such as overheat protection, water inlet detecting protection, and can operate safely for a long term in harsh working conditions.

The pump is applicable for pumping sand for building, silty sand, silt, tailing slurry, ore, iron sand ore, sediment in sewage treatment works, etc.

The pump is mainly for metallurgy,coal mine ,Coal-fired Power Plants,sewage treatment project pumping sand , silty sand, silt,
