The armoured magnetically-coupled pumps of the CM series are designed to meet chemical process industry standards. Their hermetically sealed design makes them a safe pumping solution for problematic chemicals and solvents 


Materials
The chemical pumps are available in PP, PVDF as well as in corrosion-resistant PFA for universal fluid compatibility.


Performance data
Pump capacity:
up to 180 m³/h
Total differential head:
up to 65 m
Operating temperature [t]:
-20°C up to +150 °C
Operating pressure [p]:
up to 16 bar
Diameter of discharge nozzle:
DN 25 up to DN 65
Drive rating [P]:
up to 30 kW


Applications
The CM-series pumps are used for the safe pumping of fluids posing an environmental or health hazard such as acids, alkalis, solvents and chemically contaminated fluids in the presence or in the absence of solids. Their hermetically sealed design makes them excellently suited to sensitive applications involving major hazards to humans and the environment.

Construction
Horizontal centrifugal pump, process pump design
Casing dimensions, fitting dimensions and design to EN 22858/ISO 2858/ISO 5199;
Complemented by size 40-25-125 and 40-25-160


Spacer can
The spacer can is designed as a metal-free double-wall unit consisting of an outer shell and a separate spacer can liner. Essentially, this offers the following advantages:
- No eddy currents and hence, no heat transfer to the fluid pumped.
- No energy losses and hence, no efficiency losses.
- Spacer can protected from mechanical contact with the outer magnet assembly; proximity monitor available as an option.


Plain bearing
The standard construction material for the plain bearing is silicon carbide. This advanced plastic features unsurpassed corrosion and wear resistance. Even our standard bearing model can tolerate temporary dry running or lubricant shortage.
