NPK Series Highly Wear Resistant
Heavy-duty pumps made of highly wear-resistant casting material. The main areas of application for the metallic centrifugal pumps of the NPK series are applications with medium to high wear and tear.
Characteristics
By using selected material qualities, this type of pump can also be used with corrosive/abrasive media with a particle size of up to 100 mm.
Impeller, wear plates and housing are dimensioned according to the requirements and optimized to achieve the best possible service life.
Even under the toughest operating conditions, the NPK series achieves the lowest life cycle costs.
The NPK series is a single-stage centrifugal pump with easily replaceable wearing parts and the possibility of adjusting the suction gap. The housing and the wear plates are braced via the two housing covers using tie rods.
The wear and corrosion resistant HBN materials are a result of our continuous research and development work.
