WNP series pump’s main characteristic is the S tube. Transport cylinder connect the discharging nozzle to insure the medium to be pumped continuously in the condition of carrying without valve. Some material with diameter reach the 80% of discharging nozzle can also be pumped easily.

     In some special situation like the transport pressure is very high, when the S tube transform, few backflow will happen. However the backflow is less than the 5% of the stroke volume. In this situation, we advise adopt buffering system to prevent backflow.

     WNP pump’s structure make the medium flow freely. So even for the material hard to deliver.

Simple structure design and few mobile parts make the abrading few. So it has long life and suit for 3 shift work.

     WNP pump is suit to deliver the material of high viscosity and high solid cotent and even for the bigger diameter of material.

     WNP pump is sturdy and durable. Even in some time the large material block the pump, it will not be broken down.

     WNP sludge pump can meet the strict needs of delivery for some medium. It is apply for the following areas:

         Dewatered sludge of high solid content.

           The sludge containing other sundries.

           Greasy filth containing other sundries.

           Compounds and organic matter containing high solid content and high viscosity.

     In order to meet the special appliance, WNP/MNP can change specific components and fuction such as:

        Enhance the Stube and S piston shear a foreign body.

          When deliver in high pressure, S tube match “ear” to deliver quietly.

          The pump function automatically can prevent and eliminate congestion.

          Add the mixing propeller to deliver the medium homogeneously in the process of feeding material.

          Add agitator to the pump hopper, to solve the nonuniform medium.

          To deal with the medium corrosion,different parts adopt different material.

          Absorb material end adopt different type of feeding device.

          Buffer

          Absorption section inlet hopper pipe flange can match the agitator.
