scope:

This Technical Information Paper provides a set of guidelines developed for the horizonal end suction stock pump to supply the user and the pump and pump component manufacturer with important information to consider when designing the system and sizing, acquiring, or supplying a stock pump. Reliability, operating efficiency, operating costs, and maintenance costs are key factors in developing these guidelines.

The end suction centrifugal stock pump was developed to handle pulp and paper stock. This pump ranks between the ANSI horizontal end suction centrifugal pump for chemical processing and the demanding standards of an API pump. Along with the demand for higher flow rates, more flexibility in system design, a wider pH range of fluids and stock consistencies, there is also a need for a high quality yet cost-effective stock pump.

To further aid the reader, a list of beneficial pump and component construction, mechanical and hydraulic features is provided to augment the process of selection and specification of end suction centrifugal stock pumps. Considerations for pump installation and ongoing maintenance and operation are also briefly addressed to for the life cycle of the equipment.
