Standardized chemical pump CS


Armoured horizontal pump with mechanical seal

The armoured pumps of the NPC series are designed to meet chemical process industry standards and are ideally suited to pumping chemicals and solvents manufactured in back pull-out design.

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


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

Mechanical seals

The main construction material of the mechanical seal is silicon carbide. No other material offers better corrosion and wear resistance.

MUNSCH REA FS single mechanical seal:

The slide and counter ring is made of silicon carbide; the spring is covered with fluoroplastic.

MUNSCH REA FS/D double mechanical seal:

Product-side stationary and rotating seal rings fabricated from silicon carbide, atmosphere-side stationary seal ring made of carbon; stainless steel spring.

Shaft sleeve:

Silicon carbide
