Operating instructions
•
Before connecting up to pump: remove protective coverings from suction and discharge
branches.
•
To protect the shaft sealing (especially mechanical seals) against foreign bodies, it is
recommended that a sieve, 800 micron, is installed in the suction/intake pipe when the motor is
being started up.
•
Before starting up, the pipe system, fittings and equipment must be cleaned to remove weld
spatter, scale etc.. Any pollutants are to be completely removed from pump units that are directly
or indirectly connected to drinking water systems before being installed and taken into use.
•
If the pipe system is tested with the pump installed,
do not exceed the maximum permitted casing pressure of the pump and/or shaft sealing (see
Data Sheet).
•
When emptying the pipe after the pressure test, make sure that the pump is treated properly
(danger of rust and problems when starting up).
•
In the case of pumps with stuffing boxes, replace packing after pressure test (packing may be
over-compressed and thus no longer suitable for use).
Auxiliary pipes
Any sealing, flushing or cooling pipe connections must be installed. Please consult the Data Sheet
to see which pipes, pressures and quantities are necessary. The position and size of connections to
the pump are given in the Appendix, „Summary of Screwed Connections“.
The relevant detail drawing of the shaft sealing contains a diagrammatic proposal for the pipework
and fittings. This proposal does not take into account the safety requirements for each specific
pump unit.
Point 1.4, „Sealing, flushing, cooling“ must be observed as regards regulation and
monitoring.
It is recommended that a pipeline is installed to take off any leakage from the shaft seal. For
connection, see Appendix, „Summary of Screwed Connections“.
4.4 Electrical connection
Electrical connection work may only be carried out by an authorised professional.
The rules and regulations valid for electrical technology, especially those concerned
with safety measures, must be observed. The regulations of the national power
supply companies operating in that area must also be observed.
Before starting work, check that the information on the motor rating plate is the same as the local
mains network. The power supply cable of the coupled drive motor must be connected up in
accordance with the wiring diagram produced by the motor manufacturer.
A protective motor switch is to be provided.
The direction of rotation should only be checked when the pump is full. Dry
running will cause damage to the pump.
