NPP Paper Pulp Pump

The product line offers a wide range of hydraulic sizes to guarantee minimum power consumption. Pump hydraulics, casings and impellers are designed to optimize fluid handling capabilities. Stocks are pumped like water. Particles in sludges do not accumulate in the pump, or slurries are effectively channeled so as not to cause wear.

The back vanes of the impeller keep the area between the impeller and the casing cover clean, and reduce the axial load on the bearings.Balance holes in the impeller are used to stabilize the pressure in the seal chamber. The balance holes can be plugged to optimize the shaft seal environment, should the application demand it.

The impeller hub design ensures a smooth flow and helps to avoid spinning and plugging.The reverse sides of same size impellers on the APP, NPP and WPP pumps are of equal dimensions. It is possible, therefore, to use the same casing covers for all impellers. This reduces the number of spare parts required.
