In-line pumps – slim and efficient

Heating, air-conditioning and ventilation systems are largely responsible for the interior climate in buildings. The in-line pumps installed for this purpose have got a major impact on our well-being. A good reason to opt for state-of-the-art pump technology from KSB. Our extended range of high-efficiency in-line pumps perfectly covers all applications in the fields of heating, ventilation and air conditioning. When you combine these with KSB’s comprehensive service portfolio and extras for an even higher energy efficiency, you will find that KSB offers a matching solution for every requirement.

Benefits of a KSB in-line pump

  • High performing in many building services applications
  • Constant output also in tight spaces due to compact design
  • Suitable for a large number of applications with horizontal or vertical installation options
  • Also for complex building structures such as high-rise buildings requiring large pump heads

This is how in-line-pumps work

In-line pumps are centrifugal pumps whose pump discharge and pump suction nozzles lie in a straight line of piping. In-line pumps are designed with the suction nozzle and discharge nozzle on the same axis, with the same nominal diameter. This special type of centrifugal pump can be installed directly in the piping system. Due to the above characteristics in-line pumps have become well-established, especially in building services applications. 
Like other pumps, in-line pumps are available as glanded (dry rotor) pumps and glandless (wet rotor) pumps. The selection depends on the application and the fluid to be pumped.
Glanded pumps achieve markedly higher efficiencies, which is why they are especially used for high output requirements and very large flow rates. As the motors of this design are not in contact with the fluid handled, this type of in-line pump is particularly suitable for aggressive fluids.
In glandless pumps, the rotor rotates in a can, which is filled with the fluid to be handled. Since glandless pumps are much more quiet to operate, they are particularly suitable for areas where noise is to be kept down, for example in living quarters. They are also a good choice for low output requirements and when the fluid has to be completely sealed to atmosphere.

KSB in-line pumps: variants and applications

In-line pumps are used in many building services applications, such as heating systems, air-conditioning systems, cooling circuits, service water supply systems, swimming pool systems, industrial recirculation systems and water supply.
Popular types of in-line pumps:
  • In-line pump with screwed connections (also called screw-ended pump)
  • In-line pump with flange connections (also called flanged pump)
  • In-line pump with welded connections (also called welded-in pump)
Some models are available as single pumps or twin pumps. Depending on the application and the discharge head to be generated, in-line pumps can be selected in single-stage or multistage design.
