  • Durability.

What is a Magnetic Drive?

The Magnetic Drives are used for non-contact transmission of torque.

Their advantage is that there is no material connection between the torque transmitting components. Vibrations on the drive side are dampened. At the same time Magnetic Drives represent a simple form of Overload protection for the power drive.

Under Ideal conditions they operate without any mechanical wear whatsoever, and they will enjoy virtually limitless life provided the operating condition and

design have been properly selected.

Why Sealless Magnetic Drive?

  • ›Intrinsically Safe Design by Complete elimination of Mechanical Seals and Gland Seals.
  • ›No Mechanical Seal Support System to monitor or maintain.
  • ›Complete Sealless design by the introduction of Hermetically sealed Isolation Shell. Process fluid remains where they belong inside the system.

›Reliable in Service and Simple to maintain.
