Magnetically Coupled Gear Pumps

Doug Robinson31 Jul, 2021Business

Traditional external gear pumps utilize a motor shaft which is directly coupled to a driving gear within the pump. To make this coupling, the shaft must pass through a sliding seal. The typical life-limiting component in a direct drive pump is the seal. Regardless of seal type and quality, the seal will wear and eventually leak. Magnetically coupled gear pumps avoid the life-limiting seal by using a magnetic coupling to transfer torque into the pump. This establishes a hermetic seal while still coupling the motor to the driving gear.
