  • Boiler and Feedwater Pump Efficiency Optimization

    The feedwater pump discharge pressures can vary between 875 and 1000 psi depending upon boiler demand. Differential pressure between the two points can be up to 200 psi, (or even higher in system upset conditions). This differential pressure must be accurately measured, without regard to the 800 psi and above changing boiler drum static pressure.Learn More

  • Calculate the total head of a boiler feed water pump

    Apr 23, 2020 · A boiler feedwater pump's capacity describes its flow rate. Calculate the minimum flow and maximum flow of your operation. Determining these factors can help you size your pump. Pump experts need to know how much flow rate and head are required for your operation.Learn More

  • Boiler feed pump | KSB

    For the example we have been using the calculation will look like this: 500 BHP X 34.5 ÷ 8.337 ÷ 60 X 1.5 = 52 gpm. Another quick rule of thumb is that 1/10 of a gallon is needed for every boiler horsepower. So a 500 HP boiler will need a pump capable of delivering 50 gpm. An 800 HP boiler will need an 80 gpm pump.Learn More

  • Axial thrust | KSB

    In the case of multistage pumps with diffusers (e. g. boiler feed pumps), the axial impeller force (F 1) is largely determined by the impeller's axial position in relation to the diffuser. In the case of open radial impellers with no shrouds on the suction side, the axial force (F s ) is much lower than on closed impellers, meaning that the Learn More
