Highly robust pumps for slurry and solids
Series NPK Heavy-duty pumps made of highly wear-resistant casting material

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.

Spare parts

Our products deliver top performance for years, even under the most difficult conditions. But of course every component has to be renewed or replaced once after a very long load. Here, too, we are at your side as a reliable partner, because our products are still important to us even after delivery. Therefore, we would like to accompany and support you in the best possible way even after your purchase. Therefore, do not take any risks and trust exclusively in original spare parts and the decades of experience and high competence of Habermann Aurum Pumpen.
