MasoSine positive displacement pumps have full steam-in-place and clean-in-place compliance and can be stripped down in less than 10 minutes. This technology provides gentle and low shear product handling capability. The pumps feature a sinusoidal rotor that delivers a smooth, wave-like action. The single rotor design offers very low propulsion, while large pumping chambers help preserve and maintain product integrity. When used in confectionary applications, substances are pumped from the inlet port to the higher-pressure discharge port. The rotor is powered by a single motor shaft. The scraper gate prevents any liquid flowing back from the discharge side to the lower pressure suction side of the pump. Since the chamber volume does not change, the system is suited for pumping liquids containing soft solids or viscous media, such as chocolate spread. The unit's ability to operate under high vacuum virtually eliminates shaft seal problems.
