Upgrading boiler feed pumps to increase productivity at varying capacities can reduce the longevity of the pump if certain technical points are not considered. Pump manufacturers can preserve heavy-duty applications by accurately balancing axial thrusts, maintaining net positive suction head, and executing pump protection and control.
Feed pumps that use demineralized water are designed to operate in high-temperature and high-pressure conditions. Also known as boiler feed pumps, these units can be found in applications that produce steam using treated water. These pumps require uninterrupted operation and low inlet pressures. If the required feed water is not appropriately controlled, the demand from these pumps can result in cavitation.
