3.
Install the pump with counter flanges. For pumps
with non-standardised connections, counter
flanges are delivered separately.
4.
It is advised to install a valve on the supply and
on the delivery connection of the pump.
5.
To avoid medium flowing back through the
pump, when idle, make sure a non-return valve
is installed.
6.
Make sure that the inlet of the pump is never
clogged.
7.1.1
Indicators
The arrow (A) on the pump foot indicates the flow
direction of the liquid. The arrow (B) on the top
bracket indicates the rotating direction of the motor.
7.1.2
Install bypass
Install a bypass if the pump operates against a closed
valve. The required capacity of the bypass is at least
10% of the optimum volume flow. At high operating
temperatures a higher volume flow is required. Refer
to the table "Minimum volume flows" in the paragraph
"Working range".
7.2
Mounting a motor on the
pump
ATTENTION
It is advised to use a specially designed
KSB motor. Before installing an other
brand/standard IEC-norm motor, KSB
has to be consulted to verify the
applicability.
The motor has to conform to the following conditions:
•
Reinforced bearing at driven end (to withstand
the axial force)
•
Axially fixed rotor (to minimize the axial play of
the pumps hydraulic)
•
Smooth shaft, no key lock (to improve the
coupling grip and to improve the motor balance)
The advised bearings per motor type are:
Table 15: Minimum required motor Driven-end
bearing
Or use a thrust bearing housing.
