Grundfos NB close-coupled
and NK long-coupled end-suction pumps
The Grundfos NB/NK end-suction pumps are designed and
built for industrial applications where large volumes of
water and other liquids need to be pumped from one place
to another –efficiently and reliably.
Grundfos pumps are renowned for their unmatched reliability,
and the NB and NK pumps are no exception. These
all-round workhorses have stood the test of numerous applications
under highly variable and demanding conditions all
over the world.
Standard end-suction pumps
The Grundfos NB and NK pumps are close- or long coupled
that meet the EN 733 and EN 22858 standards.
• The Grundfos NB models are close-coupled single-stage
centrifugal pumps with the motor and the pump part
built together to a compact unit.
• The Grundfos NK models are long-coupled single-stage
centrifugal pumps of a modular design comprising a
motor, a coupling, and a pump part, mounted on a base
frame.
A variety of applications
The standard models of NB and NK pumps are suitable for
a wide range of applications, however, for special requirements
a variety of customised solutions is available.
For larger loads, or where extra pumps are required for backup,
several pumps can be installed in parallel.

Wide range of applications
• Process - Pumping of large volumes of water or other liquids for industrial processes
• Cooling - Cooling plants for industrial processing and air-conditioning units
• Heating - Heating systems for commercial buildings and district heating
• Water supply - Water supply and pressure boosting for all lines of industry
• Cleaning - Water supply and pressure boosting for all kinds of industrial cleaning processes
• Fire systems - Stand-by systems for in-house fire protection. The pumps can be equipped
with combustion engines independent of electrical supply
