 About us                                                                                                                   

 

 

 

    1. We are 20years leading professional submersible dredge pump manufacturer in China.

 

    2. Top quality of raw material castings.

 

    3. Advanced equipment with mature experiences engineers. 

 

    4. Large size factory with strictly quality control system.

 

 

 

    

 

 

 

 Submersible dredge pump overview                                                                          

 

 

 

    1. NSQ submersible dredge pump is hydraulic machinery, the motor and the pump of which are

 

        coaxially working submerged in medium.

 

    2. The wetted parts of the pump are made of high chromium wearable alloy, so the pump has good wear

 

        resistance and large flowing passage.

 

    3. Submersible dredge pump is applicable for conveying medium such as sludge, ore slurry, coal slurry, 

 

       sandstones containing big solid particles.

 

    4. The product is designed and manufactured by domestic and oversea advanced technologies.

 

    5. 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.

 

    6. 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.

 

    7. 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.

 Submersible dredge pump features                                                                           

 

 

 

    1. The unique double- impeller structure , which has a main impeller together with a mixing impeller.

 

        It can sink to the bottom of the sludge stirred into turbulence after extracted.

 

    2. The whole structure of the dry pump motor . Motor mechanical seal protection, effective to prevent the

 

        pressurized water and impurities from entering the motor cavity.
    3. The impeller, mixing impellers and other major flow components manufactured with high wear-resistant

 

        material. This special material has high wear resistance, corrosion resistance, non- clogging sewage

 

        capacity, can effectively by the larger solid particles.
    4. No suction limitation with high efficiency slag suction dredging more thoroughly.
    5. No auxiliary pumps with investment more affordable.
    6. No mixing or spraying hit with auxiliary devices easier to use.
    7. Motors submerged , without building complex ground protection and fixtures, will manage more easily.
    8. Stirring impeller direct contact with the deposition surface, dive depth by controlling the concentration,
        the concentration of control more easily.

 

    9.Triple protection: oil chamber flooding detection alarm , the motor compartment flooding detection alarm.
