Munsch CS-B Standardised Chemcial Pump

Armoured horizontal close-coupled pump with mechanical seal

The armoured close-coupled pumps of the Munsch CS-B series are 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 in the presence or absence of solids. The CS-B series has been specifically developed for applications in which the use of magnetically coupled pumps is not advisable or undesirable because of the tough service environment.

Typical applications include the chemical and pharmaceutical industries, electrolysis plants, electroplating plants and metal finishing industries

The CS-B 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.

Ceramic components and a variety of flushing options make the pumps suitable for applications involving high solid loads.


Close-coupled chemical pump design with dimensions to EN 22858/ISO 2858.

The CS-B Series pumps meet the requirements of EU Directive 2014/24/EU for use in explosion hazard zones.
