Boiler​‍​‌‍​‍‌ Feed Pump Calculation

With our free online engineering calculator, figure out boiler feed pump capacity, total dynamic head (TDH), hydraulic power, motor power, brake horsepower, and NPSH in seconds.

Introduction

A correctly sized boiler feed pump is essential to keep the boiler running without any issues. The wrong pump will not only make you waste electricity but also wear out the equipment faster.

Boiler Feed Pump Calculation Tool: A very useful tool for engineers, technical workers, plant operatives, and students – to rapidly calculate most vital pump design parameters.

All you have to do is enter your system parameters – and in a moment, your boiler’s total dynamic head, the necessary pump hydraulic/horsepower, recommended motor size etc. will be computed by the calculator.

No software downloads, installations, or any kind of registration are necessary.

The Science Behind the Boilers Feed Pump Calculation

Total Dynamic Head (TDH)

TDH is the sum of the various pressures the pump has to overcome to get water to flow through the boiler system at a certain rate. It is equal to

• Static Head
• Friction loss from pipe
• Valve flow resistance
• Safety margin

Proper calculation of TDH is one of the key criteria used for successful choice of pump.

Hydraulic Power

Hydraulic energy or pumping energy is the power necessary to push water to flow through the system.

The following are factors on which hydraulic power depends:

• H2O flow rate
• Density of water
• Gravity factor
• Total head (TDH)

Pump Shaft Power

The power consumed by a pump is the amount of work performed by the pump to overcome the internal losses caused by inefficient moving parts.

Increased pump performance leads to lower power usage.

Motor Input Power

The motor has to supply all losses from the fluid flow together with the friction losses.

This is an important factor for motors selection.

Brake Horsepower (BHP)

BHP is commonly used in the selection of pumps and motors in industrial applications.

Our calculator can convert the power units for you from kilowatts to horsepower.

NPSH Margin

Net Positive Suction Head (NPSH) is critical in preventing cavitation.

Besides improving pump reliability, a positive NPSH margin prolongs the service life of equipment.

Frequently Asked Questions (FAQ)

What is the function of a boiler feed pump?

Boiler feed pumps are meant to deliver water to steam boilers at the right pressure and flow rate to generate steam safely and efficiently.

Explanation of Total Dynamic Head (TDH)

Total Dynamic Head (TDH) is the total resistance that a pump has to overcome. It includes, besides static head, the piping friction head, valve head and also any safety margin that is an additional head.

Why should we concern ourselves with pump efficiency?

More energy saving and operating cost reduction are the major advantages besides the extension of the pump and motor service life.

What is Brake Horsepower (BHP)?

Brake horsepower (BHP) is the pump shaft power before the motor efficiency is subtracted from it.

Elaborating the meaning of NPSH.

Net Positive Suction Head is the amount of pressure that is at the pump suction point measured in feet or meters of head. Keeping a good level of NPSH reduces the risk of cavitation and protects the pump from damage.
