Application
These pumps are suitable for pumping clear liquids from
tube well, open well, reservoirs and for sprinkler installations. These
are also suitable for handling boiler water fuel oil, condensate
and other liquids, containing gases.
Construction
The standard construction is horizontal foot mounted design
single or multistage radially split with intermediate casing clamped
together by external tie bolts and sealed with gaskets.
Suction and Delivery Nozzles
The standard design is vertical delivery and suction in
nozzle oval shape flanges for low head and low capacities and round
flanges for high head and higher capacities. The suction nozzle
is normally near the driving end.
Drive
The prime mover is directly connected to the pump through a flexible coupling
Speed
Maximum permissible speed is 2800 R.P.M.
Direction of Rotation
The direction of rotation is clockwise as viewed from the coupling.
Sealing Arrangement
Conventional soft graphited packed stuffing boxes are
incorporated. For special application special design for stuffing boxes
or mechanical seals can be fitted, if required.
Designs
These pumps are regenerative type. These are suitable for
liquids from a depth of 8 meters.These are available with hot water
construction suitable for operating 140% C.

What
are Boiler Feed Pumps?
As the name implies, Boiler feed pumps (also known as feed pumps) supply a boiler, a nuclear reactor or any other steam generator with feed water that is proportionate to the amount of steam generated.
Majority of the boiler feed pumps in use today are centrifugal pumps. Earlier, they were made of unalloyed steels, but today boiler feed pumps are made with steel that has a chrome content of 13-14%. Today, boiler feed pumps have a rotational speed even more than 6000 rpm, thanks to erosion and corrosion resistant materials like chrome steels that have anti-seizure properties and the advance in the technology of all pump components (including shaft seal, bearings and pump hydraulic system).
Why the Boiler Feed Pump matters in an Industrial Steam Boiler?
An industrial steam boiler is a highly pressurised tank. To avoid catastrophic failures, it’s essential that it always has the right amount of water. To ensure the correct water levels, the feed water pump must have a flow that is always higher than what’s required by the boiler for regular error-free operation.
Additionally, other factors like the vented-receiver, temperature all have an impact on the mechanical design & seal of the boiler feed pumps.
Steam boilers are used in various industries. They are available in a broad range of sizes, horsepower (100 to 1200) and design pressure (150 to 500 psig). ?
Additionally, it’s common practice to use more than one boiler parallel to one another in several industries.

Two Common Types of Feed-water pumping system designs are:
- Direct Feed – This is the most commonly used system. It’s easy to maintain, and you can switch out a pump without impacting the rest of the system.
- Booster Sets – In this type of system, there are no individual feed pumps. The boilers aren’t directly connected to supply Instead, there’s a booster set that provides water to a standard storage system. The water then moves from the common manifold to individual boilers with the help of a modulating feed water valve.
