7. Commissioning and
operations
All connections must be checked before the pump is
placed into operation. You must make sure that the
suction and pressure side of the pump is open.
The pump must run easily and smoothly. To inspect
it, remove the fan guard and turn the pump shaft a
few turns by hand on the fan wheel. Then mount the
fan guard again.
When you start the pump up, check the rotational
direction. It must match the direction of the arrow on
the pressure housing.
The reservoir must be filled with fluid up to the level
specified in "Positioning".
The pump must not be allowed to run
dry. The pump can be damaged if the
rotational direction is incorrect or if the
pump is allowed to run dry.
You must also make sure that there is no dirt in the
reservoir or pipeline system and that the upstream
filters are working properly.
PSR
Place the pump into operation as follows:
•
If there is a shut*off valve on the pressure side,
open it completely. Otherwise, make sure that
the pressure*side connection is clear.
•
Switch the pump on and check the rotational
direction. It must match the direction of the
arrow on the motor fan guard.
•
Let the pump run until a stable delivery state is
achieved, i.e. when there are no more air
bubbles in the conveyed medium.
•
You can now set the required delivery rate using
the shut*off valve on the pressure side.
These pumps should be used in continuous
operation wherever possible. If this is not possible for
technical reasons relating to the process at hand, the
constant delivery rate of the pump can be controlled
by means of a control valve, for example.
If the pump is operated in intermittent mode with
short intervals, please ask your supplier for advice.
