The principle of the TM pump magnet drive is the driving force of the pole-to-pole alignment of 2 magnets. The driven magnet is attached to the pump shaft within the pump, while the driving magnet is attached to the motor shaft and closely located to the driven magnet. By means of magnetic attraction, the pump rotates in response to motor shaft rotation.
The TM 300-400 Magnet Drive Rotary Vane Pump housing is AISI 303 stainless steel with carbon graphite internal components. The pumps can be equipped with an optional built-in relief/bypass valve. Inlet and outlet ports have ½” NPT female threads. All models are available with NBR, Viton, or EPDM static seals. Compared to conventional coupling, the magnet drive has several advantages:
- Immediate decoupling upon overload
- Longer service life
- Higher efficiency
- No leaks or contamination
- Noiseless operation
