Roto’s range of heavy-duty semi-hygienic progressing cavity pumps is designed for handling food and beverage products. All wetted parts are engineered using smooth finish stainless steel, ensuring high sanitary characteristics. Also called food pumps, these hygienic units are provided with metal bonded aseptic food-grade stator that is resistant to oil and fats. The Roto food pumps are available in close-coupled and bare shaft configurations and may be further customised for highly viscous and non-flowable liquids.

ROTO’s PCP pump comprises a precision-machined single external helix metallic rotor that rotates inside an internal double helix elastomer stator. The special construction and material of this pump allow it to create a sealing line along the axis of the rotor that is maintained in both static and dynamic conditions. As the rotor turns within the stator and fluid enters the pump, cavities are formed and progress as fluid is moved from the suction to the discharge side.
