A composite, reinforced hose is enclosed within a casing that is flanged at both ends. The flanges are connected to the suction and discharge lines of the system. Within the casing is a rotor with two pressing shoes at opposite points about its centre line and mounted on a shaft with two bearings. As the rotor rotates, the hose is totally compressed by the shoes and the product within the hose is pushed forward. At the front of the pump is a removable cover with inspection window and level indicator. The pump casing is filled to approx. half way level with a specially compounded (food grade) lubricant which functions as a coolant as well. The patented hose is constructed from rubber laminations with an internal reinforcement which ensures that compression forces are evenly applied across its full width.
