Magnet Gear Pumps
Magnetic gear pumps
The magnetic gear pump from WITTE is a particularly reliable gear pump that is frequently used in chemical applications.
- Magnetic gear pumps of the CHEM series are extremely flexible in design and can be offered in various variants and configurations thanks to a modular system.
- Magnetic gear pump for differential pressures up to 120 bar, suction pressures vacuum up to 15 bar
- Magnetic gear pump for temperatures up to max. 500 °C in combination with a magnetic coupling.
- Magnetic gear pump for viscosities up to 1,000,000 mPas or higher.
In contrast to conventional magnetic couplings, this magnetic gear pump has a separate rotor bearing. The type of bearing minimizes wear and relieves the rotor. The magnetically coupled pumps are hermetically sealed and meet the requirements of TA-Luft.
Our magnetic gear pumps for the chemical industry:
- Magnetic drive pumps
- Magnetically coupled chemical pumps
- Hermetically sealed pumps with magnetic coupling
