The Zenith 9000MD Series System

The 9000MD offers a static seal alternative to traditional mechanical and compression type dynamic seals. A permanent magnetic coupling transmits torque by magnetic forces between the internal and external rotors, through a statically sealed barrier. The barrier is constructed from stainless steel, nickel alloy or other corrosion resistant material and is not contacted by either the inner or outer rotor.

The 9000MD eliminates shaft leakage of hazardous fluids, increases plant safety, and reduces VOC emissions. The magnetic coupling also reduces downtime due to excessive mechanical seal failures and eliminates the need for buffer fluids. Zenith’s magnetically coupled pump designs include the B-9000 and C-9000 models.
