A sinusoidal pump is a type of pump featuring a sine wave-shaped rotor that creates four moving chambers, which gently convey the duty fluid from the inlet port to the higher pressure discharge port. The pump’s patented design was developed by MasoSine, an engineering company that is part of the Watson-Marlow Fluid Technology Group.
The gate prevents any fluid passing back from the discharge side to the lower-pressure suction side of the pump. The MasoSine pump is a highly reliable and economical Positive Displacement Pump for sanitary and industrial applications. Our exclusive sinusoidal rotor overcomes the limitations of conventional rotary lobe pumps to produce powerful suction with low shear, low pulsation, and gentle handling…all with simple and fast maintenance and 3-A certification.
Sine Wave-shaped Rotor
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.
