5.4
Connecting the Piping
WARNING
Danger of life when toxic or hot media are handled.
CAUTION
Never use the pump itself as an anchorage point for the piping.
Permissible forces and moments must not be exceeded (see to section 4.7).
Refer to your drawing for spool piece recommendation to ease maintenance.
Thermal expansions of the pipelines must be compensated by appropriate measures so as not to impose any extra
loads on the pump exceeding the permissible pipeline forces and moments.
An excessive, impermissible increase in the pipeline forces may cause leaks on the pump where the medium handled
can escape into the atmosphere.
The flange covers on the pump suction and discharge nozzles must be removed prior to installation in the piping.
5.4.1
Auxiliary Connections
CAUTION
These connections are required for proper functioning of the pump and are therefore of vital importance!
The dimensions and locations of the auxiliary connections (cooling, heating, sealing liquid, flushing liquid, etc.)
are indicated on the installation plan or piping layout.
5.5
Safety Guards
WARNING
In compliance with the accident prevention regulations the pump must not be operated without coupling and
drive guards. If the customer specifically requests not to include guards in our delivery, then the operator must
supply them.
5.6
Oil Temperature Monitoring
RTD (Resistance Temperature Detector) units are usually shipped separately along with the fittings needed to install them. Care
should be taken during assembly. Any fittings should be assembled and installed in the bearing housing before installing the
RTD units. Use an oil compatible sealer on the threads during installation. Be sure to tighten fittings so that any oil drain plug is
facing in the down position. After all fittings are installed, install the RTD unit. Take care not to drop or damage the RTD unit
during installation. After the entire assembly is complete, the bearing assembly can be put back into service. The assembly
should be inspected for leaks.
5.7
Final Check
Verify the alignment as described in Section 5.3.1. It must be easy to rotate the shaft 360° by hand at the coupling. For elastomer
lined pump assemblies this step should be completed after final installation of the piping. If resistance to hand rotation is observed
the nose gap may need to be reset per Section 10.4 "Setting the Nose Gap".
5.8
Connection to Power Supply
WARNING
A trained electrician must make the connection to the power supply. Check available main voltage
against the data on the motor rating plate and select the appropriate start-up method. The use of a
motor protection device is strongly recommended.
An emergency shut off switch should be installed to prevent damage to the personnel and environment
in the event of hazardous pump operation.
