Metallic centrifugal heavy duty slurry pumps of NPK series
-
Slurry, Dredge, Sand Pumps
- Horizontal
The pumps of NPK series are metallic centrifugal heavy duty slurry pumps.
The main fields of application of the metallic type of NPK centrifugal pumps are those involving high levels of wear.
Through careful selection of the best materials, NPK are also used for corrosive and abrasive media with grain sizes of up to 100 mm.
The exceptional wall thicknesses and core hardness of the main wear parts, such as impellers, casings, wear plates, provide durable performances. Thereby the NPK slurry pumps have an excellent service life and can withstand the most severe pumping conditions.
The NPK series contains single-stage centrifugal pumps with easily replaceable wear parts and re-adjustable suction gap. The tie rods assembly system (across the casing covers) helps to optimize the thread-free casing, its hardening and service life.
