Performance Ranges NK
Curve Conditions
Selection of Pumps
The guidelines below apply to the curves shown in the
performance charts on pages 35 - 106.
• Tolerances according to:
ISO 2548, Class C, annex B.
• The curves show pump performance with different
impeller diameters at the nominal speed.
• The bold part of the curves show the recommen-
ded operating range.
• The thin parts show the possible operating range
but the lower efficiency here might suggest the se-
lection of a smaller/larger pump type.
• Due to the risk of overheating, a flow rate equal to
10% of the flow rate at maximum efficiency is nee-
ded at all times.
• The curves apply to the pumping of water at a tem-
perature of +20°C and a kinematic viscosity of
1 mm²/s (1 cSt).
• ETA: The dashed lines show values of the hydraulic
efficiency of the pump.
• NPSH: The curves show average values measured
under the same conditions as the performance cur-
ves.
• When dimensioning the pump, add a safety margin
of at least 0.5 m.
Performance Tests
The requested duty point for every pump is tested
according to ISO 2548, class C, annex B and without
certification.
In case of pumps ordered with impeller diameter only
(no requested duty point), the pump will be tested at a
duty point which is 2/3 of the maximum flow of the
published performance curve which is related to the
ordered impeller diameter (according to ISO 2548,
class C, annex B).
If the customer requires either more points on the curve
to be checked or certain minimum performances or
certificates, individual measurements must be made.
Certificates
Certificates have to be confirmed for every order and
are available on request as follows:
According to EN 10204
• Certificate for compliance
with the order EN 10204 - 2.1
• Pump certificate EN 10204 - 2.2
• Works certificate EN 10204 - 2.3
• Inspection certificate EN 10204 - 3.1 B
• Inspection certificate EN 10204 - 3.1 C
According to ISO 2548, Class C, annex B
• Certificate A
• Certificate A with approval of official inspector.
