3.2 Storage
Pumps or pump units that are stored for a long time before use must be protected against moisture,
vibrations and dirt (e.g. by wrapping in oil paper or plastic sheeting). Pumps must basically be
stored in a place where they are protected from the weather, e.g. under cover. During this time, all
suction and discharge branches and all other intakes and outlets must be closed with dummy
flanges or plugs.
4. Assembly, Operation
4.1 Preparing for Installation
• Before installing the pump the opening in the shaft cover must be checked according to the
dimensions contained in the Installation Diagram (No. M 473 in the Appendix).
• The seat for the base plate (Position 380 in the sectional drawing) must be horizontal.
• The shaft must be at least 100 mm deeper than the installation length of the pump (from the
plate seat to the lower surface of the pump).
4.2 Assembling and Installing the Pump
Make sure that there is sufficient space for service and maintenance work to be
carried out, especially for changing the drive motor or the whole pump unit.
The motor ventilator must be able to take in sufficient cooling air.
There must be at least 10 cm distance between the suction grid and a wall etc.
Pumps with an installation length of more than 1,900 mm are delivered in two parts which must
be fitted together as follows before being installed in the shaft.
The part of the pump which has the lower rod mounted is laid on top of the shaft cover by means
of pipe support clamps over the port. After the wooden wedges and fork have been removed the
unit's drive part can be put in place.
In addition, the shaft coupling 340
must be slipped onto the shaft
324/U, enabling the rod bearing
screws or pressure pipe screws to be
tightened. Then raise the shaft
324/U with the two screwdrivers by
the two lower bore holes of the rod
pipe 305/U lying opposite each
other (see illustration), until the two
shaft screws S4 can be screwed in
the shaft groove provided through
the two upper bore holes. Both shaft
screws must be secured with either
