NSQ 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 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 inle t 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.
Structural Property
1.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 are effectively prevented from entering inner cavity of the motor.
2.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.
3.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.
4.The motor is submerged in water, is not limited by suction stroke, and has high sludge suction rate and thorough desilting.
5.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.
6.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.
Use Conditions
1 The power source is 50Hz/380V three-phase alternating-current supply, and the capacity of the substation transformator is two to three times of the rated capacity of the motor.
2 The temperature of the medium cannot exceed 60íµ, and the medium does not contain inflammable or explosive gases.
3 The maximum weight concentration of the solid particles in the medium: the maximum weight concentration of the ash is 45% and the maximum weight concentration of the slag is 60%.
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.
Weight is 210KG.

Hydroman Electric Submersible Slurry Pump in Stainless Steel for Acid Mine also known as stainless steel submersible slurry pump are designed to provide the mining and industrial processing markets with unparalleled resistance to corrosion and abrasion, polluted water in the sea or the rivers also requires these stainless steel submersible pumps. Hydroman submersible stainless steel slurry pump is an extremely durable, top-discharge slurry submersible pump with a mechanical agitator and wide clearances. This submersible slurry pump uses the pumped liquid to cool the motor. The pumping components of the submersible sea water sand pump, notably the agitator, impeller and wear plate are constructed of stainless steel, meaning the submersible sand slurry pump is designed to be a solid workhorse in any condition. Hydroman Electric Submersible Slurry Pump in Stainless Steel for Acid Mine Features Best structure design of submersible sand pump, has a dry motor, IP68, double mechanical seals, equipped with an auto-cut protection, pump casting, outer cover is stainless steel, and acid-resistant silicon carbide seals. The stainless series submersible agitator slurry pump is suitable for all light acid, corrosive and/or sea water application fluid in pH values between 4 to 10pH. For strong acidity and alkalinity applications, please use the specified chemical vertical submerged pump. Investment Casting Precision casting with the use of an advanced stainless investment casting method that produces the highest quality with a smooth surface finish. Viton O-rings are used throughout the stainless steel submersible slurry agitator pump to give better pump life in corrosive acid and aggressive media. Austenitic Stainless Steel SS316 water application of light acid-base.
Hydroman Hydraulic Submersible Slurry Pump is protected by a mechanical seal, which can effectively prevent high-pressure water and impurities. In addition to the main impeller, there is also an agitating impeller for the submersible slurry pump, which can agitate the slag deposited on the bottom of the water. Plus, the mixing impeller and other main flow parts are made of advanced materials, which are wear-resistant, corrosion-resistant, non-clogging, strong in sewage, and can effectively pass larger solid particles.The slag suction efficiency is high, and the dredging is more thorough. The motor of submersible slurry pumps dives into the water, without the need to construct complex ground protection and fixing devices, and the management is easier, thus to ensure high and reliable performance.
OGEM YZ Submersible slurry pump is centrifugal pump. It is usually used to pump drilling fluid with larger particle. So it can be treated as shale shaker feeding pump. It is vertical type save much space. Furthermore, it also can be decanter centrifuge feeding pump. YZ Submersible slurry pump impeller is semi opening type this provides high efficiency. The impeller material is carbide alloy make pump more durable decrease maintenance cost. OGEM Equipment is professional manufacturer on submersible slurry pump with high quality and economical cost. Benefits 1.Request less space 2.High efficient and effect 3.Durable enough 4.Low maintenance cost 5.Better for transferring drilling fluid
