  • Page 16: Design Concept

    2.3 Design concept incorporates special features to induce flow into the pump suction and to remove air that is present in stock at higher consistencies. 2.3 Design concept There are two major obstacles in pumping paper stock at consistencies above 8% with a centrifugal pump: the formation of a fiber network that will not readily flow, and high air content which can cause air binding of a standard centrifugal pump.
  • Page 17 2.4 Construction details Impeller - The impeller is an open design with a full back shroud. It is designed for a matched close clearance with the suction sideplate to provide optimum efficiency. The impeller has balance holes to al- low air to pass through the back shroud. Remaining paper stock is returned to the casing volute via large pump-out vanes.
