Heavy duty-flap valve pumps are the ideal solution for abrasive slurries, non-suspended and line-size solids requirements. These solids handling pumps are workhorses in markets like meat and poultry because of their unique ability to pass large solids that would commonly clog other pumps.
Compared to AODD ball valve pumps and other rotating pump technologies, heavy-duty flap valve pumps are optimized to enhance performance and efficiency.
It is the attraction of the drive magnet and the impeller magnet which allows the full torque of the motor to be passed onto the impeller. As the shaft of the motor does not extend into the interior of the pump, there is no need for a shaft seal. As the impeller is not fixed to the motor shaft, the impeller floats inside the pump housings. The impeller spins, at the same speed as the motor, supported by a stationary shaft. The only moving part which touches the liquid is the impeller.
Without a shaft seal, the danger of leakage commonly associated with a shaft seal is eliminated. Furthermore, the maintenance cost is reduced because no time or money is spent on maintaining or replacing the shaft seal.
