The main applications for the metallic centrifugal pumps of the NPK series are cases with medium to high wear load.
By using selected material qualities, this type of pump can also be used for corrosive and abrasive medium with particles size of up to 100 mm.
Impeller, wear plates and pump housing are dimensioned according to the requirements and optimised to achieve the best possible service lives.
Even under the most difficult operating conditions, the NPK model series achieves the lowest lifecycle costs.
The NPK model series is comprised of single-stage centrifugal pumps with easily replaceable wear parts and adjustable suction gap. The pump housing and wear plates are braced across the case covers by means of tension rods.
The wear-resistant and corrosion-resistant HBN materials are a result of our continuous research and development activities.
- HBN 440 – wear-resistant casting, Ni-Hard IV follower
- HBN 450 – highly wear-resistant casting, hardness up to 650 HB
- HBN 480 – corrosion-resistant casting, hardness up to 650 HB
