Boiler Feed Pump - an overview | ScienceDirect Topi

To ensure the safety of large pumps, e.g., boiler feed pump (BFP), condensate extraction pump (CEP), etc., it is essential to maintain a minimum flow through the pump at all modes of operation. This control valve is located on a separate line tapped from either the individual pump discharge or the common discharge header of pumps.

Two Aspects of Deciding Between A Ring-Section and A Barrel Pull-Out Pump Are Described Below1. The smaller the mass flow rate and the higher the pressure, the higher the material and manufacturing costs of barrel pull-out pumps. This doesTapping A Stage of A Boiler Feed Pump1. In the case of ring-section pumps, a partial flow at an intermediate pressure can easily be tapped through a tapping nozzle in one of the stageBalancing of Radial Forces on The Pump RotorRadial forces arise from the weight of the rotor, mechanical unbalance or hydraulic radial thrust. The radial forces are balanced by two oil-lubricWarming Up and Keeping WarmTransient or low flow operating conditions cause additional loads on boiler feed pumps. This leads to additional stresses and strains as well as to Boiler Feed. Grundfos’ thoroughly tested, variable frequency drive pumps optimize the boiler feed process. Customized with low NPSH, these solutions cater to systems with poor inlet conditions. This ensures cavitation-free operation even outside the pump´s normal duty range.
