Armoured horizontal pump with mechanical seal
The Munsch NPC series has been specifically developed for applications in abrasive and aggressive service conditions. Designed to meet chemical process industry standards and are ideally suited to the safe pumping of fluids posing an environmental or health hazard such as acids, alkalis, solvents and chemically contaminated fluids with and without solids.
Typical applications include the chemical and pharmaceutical industries, electrolysis & electroplating plants, metal refining and general industry.
The NPC range includes the metal free Munsch REA Mechanical seal, specifically developed for non-metallic pumps to ensures maximum operating reliability and a long service life while being easy to assemble and repair. Models are available with either a single or double seal and offer easy conversion.
The armoured volute casing has a 10mm minimum thickness with no weak weld points.
Horizontal centrifugal pump, process pump design; casing and fitting dimensions to EN 22858/ISO 2858; complemented by size 40-25-160 and 40-25-160
The NPC Series pumps meet the requirements of EU Directive No 94/9/EG for use in explosion hazard zones.
