Mechanical seals

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

MUNSCH REA F single mechanical seal:

Stationary and rotating seal rings fabricated from silicon carbide; the spring is encapsulated in fluoroplastics.

MUNSCH REA F/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:

Fluoroplastics-coated stainless steel.
