Introduction
Use this conversion guide to find the right CM pump
type when a CH, CHN or CHI pump is to be replaced.
Recommended selection of pump
material version
Three material versions of the CM pump are available,
see the table below:

Adapter base plate
Since the CM pumps have been designed with
compactness in focus, they require significantly less
space than the CH(N) and CHI(E) pumps. Furthermore,
the distance between suction and discharge ports has
been changed. Therefore, it may be necessary to use
an adapter base plate (fig. 1) when an existing CH(N)
or CHI(E) pump is to be replaced by a CM pump.

Selection of shaft seal
The table below contains the available shaft seal types
for CH- and CM-pump types. In the table it is possible
to see a recommended selection of shaft seal when
replacing an existing CH, CHN or CHI pump with a

Result
• If a lower head is acceptable, choose a CM 5-2-A
pump, i.e. duty point B.
• A CM 3-5-A pump is an almost exact match, i.e.
duty point F.
• If a higher head is acceptable, choose a CM 5-3-A
pump, i.e. duty point C.
• If a lower head is acceptable, choose a CM 5-4-A

How to read the curve charts
Guidelines to performance curves
The guidelines below apply to the curves shown on the
following pages:
• Tolerances to ISO 9906, Annex A.
• The motors used for measurements of the CM pumps
are the specifically designed motors for CM pumps.
The motors are based on Grundfos standard motors
(MG).
• Measurements have been made with airless water at
a temperature of +20 °C.
• The curves apply to the following kinematic viscosity:
υ = 1 mm2/s (1 cSt).
• The QH for CM pump curves apply to rated motor
speeds of approximately 2900 min-1 (50 Hz) and
approximately 3400 min-1 (60 Hz). All CM curves are
based on current motor speeds.
Note: Please refer to WebCAPS for more precise
curves. In WebCAPS, it is also possible to adjust the
curves depending on the density and viscosity.
• When the motor is running at the lowest or highest
rated voltage, the pump performance will usually
vary by ± 0.5 - 1.0 m at a given duty point.
• All curves are based on pumps fitted with a threephase motor.
• The conversion between head H (m) and pressure p
(kPa) applies to a water density of ρ = 1000 kg/m3.
• Due to the risk of overheating, the CM pumps should
not be used at a flow below the minimum flow rate.
The curve in fig. 5 shows the minimum flow rate as a
percentage of the rated flow rate in relation to the
liquid temperature.
