Performance data

Applications

The type NPC MUNSCH Mammut pump is specifically designed to handle acids, alkalis or chemically contaminated fluids with or without solids loads. Typical applications include the chemical and metallurgical industries, the metal finishing industry, steel and stainless steel pickling lines, evaporation and regeneration units, flue gas cleaning systems downstream of waste incinerators as well as exhaust gas scrubbing and scrubber effluent treatment.

Construction

Horizontal centrifugal pump with split volute casing and single-entry, single-stage radial impeller. Meets the technical requirement for Class II centrifugal pumps as per EN ISO 5199.

Mechanical seal

Single mechanical seal - direction of rotation-independent, metal-free MUNSCH REA-IV mechanical seal, insensitive to solids.

Double mechanical seal - Shaft sealing solution for fluids posing an environmental hazard.

Shaft sleeve:

Fluoroplastics-coated stainless steel.
