Close-coupled chemical pump NPC-B


Armoured horizontal pump with mechanical seal

The armoured close-coupled pumps of the NPC-B series are designed to meet chemical process industry standards and are ideally suited to pumping chemicals and solvents.

The MUNSCH REA mechanical seal, specifically developed for non-metallic pumps, ensures maximum operating reliability and a long service life while being easy to assembly and repair.


The chemical pumps are available in PP, PVDF as well as in corrosion-resistant PFA for universal fluid compatibility.
