Maximum operating reliability and a long service life hinge on a powerful mechanical seal. The MUNSCH REA mechanical seal, specifically developed for non-metallic pumps, answers to all operator needs.  

Applications:
The NP-B pump series is excellently suited to pumping tasks in the chemical industry, electroplating plants, steel and stainless steel pickling lines, evaporation and regeneration units, wet flue gas cleaning systems downstream of waste incinerators as well as in exhaust air scrubbing and industrial waste water treatment.

Construction:
Horizontal centrifugal pump with volute casing;
casing and fitting dimensions to EN 22858/ISO 2858;
complemented by Size 40 25 125 and 40 25 160 pumps.

The chemical pumps are available in PP, PE-UHMW as well as PVDF.

Mechanical seals 

All silicon carbide components are fabricated from  EKasic® C known for its unsurpassed wear and corrosion resistance properties.

MUNSCH‑REA‑C single mechanical seal:

Stationary and rotating seal rings fabricated from EKasic® C; the spring is encapsulated in fluoroplastics.
Shaft sleeve

Fluoroplastics-coated stainless steel.

A new generation, thought through to the minute detail and a safe solution for every application – the uncompromising answer to what EPC contractors and plant operators expect from chemical pumps with mechanical seal.

Applications:
NPC chemical pumps are the solution of choice for pumping fluids posing an environmental or health hazard such as acids and alkalis or solvents in the presence or in the absence of solids.
Typical applications include the chemical and pharmaceutical industries, electrolysis plants, electroplating plants and metal finishing processes.   

Construction:
NPC standardized chemical pump with dimensions to EN 22858/ISO 2858/ISO 5199; complemented by Size 40 25 125 and 40 25 160 pumps.
