CTM Magnetic drive pumps

Overview

CTM pumps are used in most industries where liquids are pumped. The pumps handle many types of low and normal viscous clean liquids such as chemical aggressive and toxic.

Key components

CTM working principle.en

CTM is a close coupled compact pump ideal for service in little spaces like in OEM installations.
Non-metallic pumps
The wetted components are non-metallic injection moulded thermoplastics enabling excellent corrosion resistance.
The version in PP-GF (glass fibre reinforced polypropylene) provides great mechanical strength and allows liquid temperatures up to 70°C.
The PVDF (PolyVinylidine DiFluoride) version has the superior chemical resistance and allows temperatures up to 80°C. 

The reliable design without shaft

The impeller magnet assembly is designed with very powerful bushings where a conventional crack sensitive shaft is not needed. This results in a pump that has fewer parts and is very reliable in service.

Excellent performance with magnet cage system

Our magnets in NdFeB (Neodymium-iron-boron) with our patent pending magnet cage system have a superior strength also under demanding circumstances. The power from the drive is transmitted even at high temperatures and with high specific gravity liquids.

Working principle

CTM working principle.en

How they work

The power from the motor is transmitted to the centrifugal impeller by means of a magnetic coupling. A so called isolation shell between the drive magnet and the impeller magnet separate the liquid side from the drive.

Working principle
1) Drive magnet, connected to the motor
2) Isolation shell (rear housing) separating the liquid side from the atmosphere
3) Impeller magnet assembly, driven by the drive magnet

Certificates


fda

FDA §21 CFR 177 materials
FDA (U.S. Food and Drug Administration) §21 CFR 177 lists polymers, e.g. rubber and plastic materials approved for equipment in contact with food products.



EN 10204

EN 10204 material traceability
The EN 10204 norm gives you a checklist and traceability of materials used in the equipment. 2.1 is a general statement of compliance with material specifications, while 3.1 provides specific track records all the way to the steel mill batch (normally only on metals in contact with the product).
