Magnetically Driven Centrifugal Pump

The CTM Magnetically Driven Centrifugal Pump range from Tapflo is ideal for handling low and normal viscous liquids. The sealless design feature of a magnetic drive pump ensures it is airtight, minimising the risk of fluid and vapour leakage from the pump.

Tech Info

Performance

Varying from the standard centrifugal pumping mechanism, Magnetically Driven Centrifugal Pumps are designed so that the motor is coupled to the pump by magnets, instead of a direct mechanical shaft. The drive magnet works the pump, ‘driving’ the pump rotor, which is magnetically coupled to the primary shaft driven by the motor. Magnetic Pumps are used in industries where leakage of the agent being pumped could cause damage, such as in the chemical or nuclear industries where hazardous fluids are typically present. The Centrifugal Pumps are Magnetical Driven End Suction, Close Coupled, Single Stage Centrifugal Pumps feature a Semi-Open or Closed Impeller and are manufactured from either Glass Fibre Reinforced Polypropylene or PVDF to offer high mechanical and corrosion resistance for a plethora of applications at competitive pricing.

The CTM Mag Drive Centrifugal Pump is a close-coupled compact pump ideal for service in little spaces like in OEM installations. Benefits include:

Reliable design
Efficient operating
No mechanical seal problems
Safe handling of hazardous fluids
Hermetic System

The wetted components are non-metallic injection moulded thermoplastics enabling excellent corrosion resistance.

Magnet Cage System

The magnets are totally encapsulated in their cage with a unique system that avoids the use of resins and glue. This grants a safe system with better performance at high temperatures. Furthermore, the impeller is injection moulded, resulting in excellent performance and no weak points.

Applications

The CTM Centrifugal Pumps range is perfectly suited for a wide variety of applications for clean & thin liquids like pure chemicals, acids & alkalis. It is especially useful for chemically corrosive and toxic liquids.
