Applications
Flexible Coupling
The pump is suitable for the pumping of thin, clean and
non-aggressive liquids without solid particles or fibres
in:
Standard version or a spacer coupling which allows the
motor to remain in place during the above mentioned
dismantling to avoid subsequent alignment.
If the pump housing, motor or the entire unit is moved,
alignment is always neccessary.
• District heating
• Water supply
• Airconditioning
Bearing Assembly with Shaft
• Cooling plants
The bearing assembly includes two sturdy antifriction
bearings lubricated for life. Oversize pumps with shaft
d5 = 55 mm however, have open bearings with grease
nipples.
• Industry
• Fire fighting
• Environment engineering
A thrower on the shaft prevents liquid from entering the
bearing housing.
Operating Conditions
In stuffing box versions the shaft is protected by a stainless steel sleeve at the shaft seal.
Flow
Max. 2000 m 3/h.
Head
Max. 150 m.
Liquid
Temperature
–40°C up to +160°C.
Operating
Pressure
Max. 10 or 16 bar.
Operating pressure = inlet pressure +
pressure against a closed valve (Q = 0).
Inlet
Pressure
Max. 9 bar.
Max. 7 bar for 400 mm impellers or bigger.
All the NK pumps according to DIN 24 255 are covered
by only four sizes of shaft, shaft seal and bearings, and
the oversizes by an additional three sizes.
Due to the ample sizes of the bearings and shaft the NK
pumps can be driven by a belt drive, belt variator or a
diesel engine, if required.
Pump
Shaft Seal
Non-self-priming single-stage centrifugal volute pump
with axial suction port, radial discharge port and horizontal shaft components.
The standard version is provided with a mechanical
Burgmann shaft seal according to DIN 24 960,
Grundfos type BAQE. Depending on pumped liquid and
operating conditions other types and stuffing boxes are
available.
The NK pumps have dimensions and nominal performances according to DIN 24 255 (10 bar) but are
designed for 16 bar operation wherever the shaft seal
type allows it. NKG pumps according to DIN 24 256 (16
bar) are described in a separate booklet.
Types outside of the official DIN-norm (NK 200 and up)
will be called "oversize". Dimensions can differ from
other suppliers.
The suction and discharge flanges are according to DIN
2501 PN 10 or 16. All pumps are dynamically balanced
according to ISO 1940 class 6.3 and impellers are
hydraulically balanced.
Pump and motor are mounted on a common baseplate
in accordance with DIN 24 259 in all-welded steel.
Oversizes have profile base frames.
Due to the pump design the complete bearing assembly
including impeller and shaft seal can be dismantled
without removing the volute casing from the pipe
system (back-pull-out system 3 ).
Back-to-back double mechanical shaft seals, and
"quench", are available for all variants on request.
Motor
The motor is a totally enclosed, fan-cooled squirrelcage Grundfos MMG motor dimensioned to IEC publication 72 and complying with IEC 34 and DIN 42 950.

The power required to achieve the requested duty point
can be found by means of the power chart below the
performance chart (see pages 35-106). Find the power
curve corresponding to the required QH-value (or interpolate between curves).
When deciding the motor size a safety margin acc. ISO
5199 must be added.
To decide the motor size select the P2 that is the
nearest higher than the required power, and choose the
motor size next to it.

(according to pump version).
(The service kit items will cover service for two
years of normal operation).
Ambient Temperature
–30°C to +40°C.
Due to the low density and consequent low cooling
effect of the air, operation at an ambient temperature
above 40°C or at an altitude exceeding 1000 m above
sea level requires a reduction of the rated motor load.

Oversizes
The DIN 24 255 describes only the standard types
mentioned in the table on page 18.
The NK range is extended with bigger models (oversizes) for higher flows and pressures.
As a consequence bracket sizes, flange dimensions
etc. for the oversize pumps can be different from other
suppliers.
