What makes the CS standardized chemical pump so special?

  • High wear and diffusion reserves through thick-walled plastic casing
  • Latest hydraulic design and manufacturing methods for energy efficiency and minimized wear
  • Suitable for solids-carrying and hazardous fluids including high-temperature applications
  • Metal-free mechanical seal with diverse flushing options – perfectly matched to the process
  • Ease of maintenance and reduced spare parts inventory through standardized components, high availability and ease of field assembly without the need for any special skills

High-quality construction materials

MUNSCH CS chemical pumps are available in the following main materials: PP, PVDF and PTFE/ PFA for virtually universal fluid resistance


-20 …180°C

Universally applicable fluoropolymer; suitable for organic and inorganic fluids


-20 …120 °C

Versatile, partially fluorinated plastic; depending on the application, an economical alternative to PFA.


0 … 90 °C

Good resistance to many inorganic acids; offers excellent wear properties.

Tailor-made mechanical seal

Each MUNSCH shaft seal is matched to the specific application. Being the linchpin in the pump system, the mechanical seal must be right for you – and for your pumping task.

As MUNSCH pumps operate in demanding service environments, the seal as well must satisfy exacting demands. To ensure the highest standards of quality, we have developed a seal offering maximum reliability in tough service conditions while at the same time being individually configurable: the MUNSCH REA-F (S/V).

Its flexibility and adaptability notwithstanding, this metal-free seal comes with a high level of standardization: one seal size fits all the pumps of the CS series. In this way, MUNSCH helps you simplify spare parts inventory management and creates confidence on the part of your maintenance staff.

Subsequent conversion from a single to a double-acting mechanical seal or vice versa is feasible at any time with a minimum of effort. Flushing connections provided allow various flushing arrangements to be retrofitted without the need for any major modifications in the case of changed service conditions.
