CDR Pompe Lined Magnetic Drive Centrifugal Pumps

Pumps lined with Plastic and Fluorine-plastic are used to cover the total chemical compatibility with corrosives and aggressive fluids – acids or bases – from the chemical, petrochemical and pharmaceutical industries.

Those plastic magnetic drive pumps have a simple design and a small amount of spare parts to guarantee very easy maintenance. The impeller doesn’t come in contact with the shaft, so the fluids’ leakage is impossible to occur. Fluids never disperse in the environment.

We do produce two models:

  • ETN EVO: a lined magnetic drive pump equipped with spare parts lined in ETFE or polypropylene. These plastic-lined pumps are suitable for chemical, petrochemical and pharmaceutical industries.
  • UTN-L / UTN-BL: a magnetic drive-lined process pump (ISO 2858), recommended to work H24 with corrosive, aggressive and dangerous fluids where high safety standards are compulsory. The materials available for this kind of pump are PP (Polypropylene), PVDF (Polyvinyl Fluoride), PFA (Perfluoroalkoxy).

Magnetic Drive Concept

The synchronous drive configuration is based on an outer magnet ring assembly built magnetically coupled with an inner magnet ring assembly.

These two magnet rings are locked together by the flux of attracting magnet poles flowing through the containment isolation shell.

Versatility

the ETN EVO offers a wide range of materials for the wetted parts:

  • PP (Polypropylene)
  • ETFE (Ethylene tetrafluoroethylene)

Reliability

New internal circulation path for top reliability, even under stress conditions

Design

Made with a reliable quality as the UTN, but designed for smaller applications (low duty)

Features:

Casing:

ETN EVO casing

  • The ductile cast iron armor protects the fluoroplastic peripheral surfaces of the pump from pipe strain, vibration, external shocks and during the handling; moreover, it allows the casing to be Vacuum resistant.

Magnetic Drive Concept

The synchronous drive configuration is based on an outer magnet ring assembly built to magnetically coupled with an inner magnet ring assembly.

These two magnet rings are locked together by the flux of attracting magnet poles flowing through the containment isolation shell.

Versatility:

suitable for handling corrosive, aggressive and hazardous liquids (low viscosity, clean or slightly contaminated) in the chemical, petrochemical and Pharma industries, where the need of high safety standards is the first requirement

Reliability:

The pump is equipped with a reliable oil-lubricated bearing bracket, especially developed to be suitable even under heavy-duty service.

Design:

UTN range shares the same hydraulic design with the UCL series (mechanical seal pumps) which have been developed focusing on the needs of the chemical industry.

Features:

Casing:
