CM standardized chemical pump

Maximum safety in highly corrosive service environments

CM standardized chemical pump

The MUNSCH CM standardized chemical pump series stands for maximum operating safety, reliability and flexibility. The magnetically-coupled configuration means built-in hermetic containment of the fluid pumped. With all liquid-contacted parts made of PFA, the CM is the solution of choice for high-temperature and highly corrosive service environments. A wide variety of safety features offers the right solution for every application.

What makes the CM standardized pump so special?

  • Suitable for handling solids-carrying and hazardous fluids, for high-temperature applications and also for unproblematic pumping tasks
  • Reduced evaporation or plugging risk through hermetically sealed design
  • Energy-efficient and minimized wear through perfect hydraulics and the latest manufacturing methods
  • Additional wear reserves through thick-walled, high-end engineered plastics
  • Many safety options available for easy and cost-effective retrofit
  • 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 CM-series chemical pumps are available in the following main materials: PP, PVDF and PTFE/ PFA for virtually universal fluid resistance.

PFA

-20 …190°C

Universally applicable fluoropolymer; suitable for organic and inorganic fluids.

PVDF

-20 …120 °C

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

PP

0 … 90 °C

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

Spacer can for hermetic containment

The CM standardized chemical pump uses a vacuum-resistant, metal-free spacer can to isolate the liquid chamber from the atmosphere. This unique MUNSCH design offers unbeatable advantages in sensitive applications:

• No eddy currents and hence no heat transfer to the fluid pumped

• No energy losses and hence guaranteed high efficiency

• The spacer can is protected from mechanical contact with the outer magnet assembly.

• An optional monitoring system provides additional protection of the pump and the process.

Wear-protected plain bearing

MUNSCH’s material of choice for the plain bearing is silicon carbide. This advanced ceramic material features unsurpassed corrosion and wear resistance. The plain bearing tolerates short-term lubricant shortage even in its standard design.

Maximum flexibility

Two pump series, one hydraulic design: the ten pump sizes of our CM series are identical in hydraulic design with the mechanical seal pumps of the CS series. Your advantage:
MUNSCH offers you maximum flexibility with regard to the sealing concept. Together with you, we select the optimum solution for your specific pumping task.
