Product Description

NSQ series Submersible Sand Pump



Product Introduction


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 medium 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,. The unique mechnical 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 condition.

Technical data



Features and advantages


 1. The whole machine is dry submersible pump and the motor adopts oil chamber seal mode and 

        is provided with mechanical seal inside, so  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 overflowing parts such as the impeller and the agitation impeller are made from high-hard-

       ness high chromium cast steel, have wear resistance, corrosion resistance,  strong drainage 

       capacity and allow big solid particles to pass.


4.  The motor is submerged in water and is not limited by suction stroke. It has high sludge suction 

      rate and thorough desilting .
