Submersible Slurry Heavy Duty Sewage Sand Suction Dredge Submersible Slurry Pump

Submersible Slurry Heavy Duty Sewage Sand Suction Dredge Submersible Slurry PumpProduct DescriptionZJQ submersible sludge pump is hydraulic machinery, the motor and the pump of which are coaxially submerged in medium to work. The overflowing parts of the pump are made from high alloy wear-resistant material, 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 over sea 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 project the reliability of the mechanical seal to the maximum extent. The motor adopts various protective such as overheat protection, water inlet detecting projection, 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 whole machine is dry submersible pump, and the motor adopts oil chamber seal mode and is provided with mechanical seal inside, so that high pressure water and impurities and are effectively prevented from entering inner cavity of the motor.1.Besides the main impeller, there is the agitation impeller which can agitate the sludge deposited on the water bottom into turbulent flow and pump the sludge out.2.The trans-flux parts such as the impeller and the agitation impeller are made from high-hardness high chromium cast steel, have wear resistance, corrosion resistance and strong drainage capacity, and allow big solid particles to pass.3.The motor is submerged in water, is not limited by suction stroke, and has high   sludge suction rate and thorough desilting.4.The integral device is simplified, needs no auxiliary stirrer device or ejector device, and has simple and convenient operation and low total investment of the unit.5.The agitation impeller directly approaches the depositional surface, and controls the concentration through submerged depth. Under the condition of large medium proportion, an auxiliary device can be arranged to increase the concentration of the medium. Detailed Photos Product ParametersFlow50m3/h-2000m3/hHead10m-60mSpeed980rpm-1460rpmPower3kw-315kwDischarge distance200m-600mDredging depthwithin35mMax.flow particle dia.allowed10-56mm NO.
