Following properties should be considered during motor selection.
- Maximum power of pump (in all operation ranges)
- Operational revolution of pump shaft
- Necessary power supply
- Motor Type
- Motor connection type (footed, flanged, horizontal, vertical etc.)
Coupling (clutch) setup is obtained by pump and motor having identical axis. All parts
of pumps mainly pump and motor bearings may have damage because of vibration
caused by unadjusted coupling.
Before start to pump installation
- Protecting parts in discharge and suction flanges should be removed and cleaned
well.
- Pump should be installed in a places which does not have freezing or explosion risk
and have well air conditioning.
- There should be enough space around pump for accessing pump easily and for
maintenance operations and there should be sufficient height and space for lifting
pump if necessary.
- Pump suction pipe should be as short as possible.
- You should be carefully work at pump installation ground preparation and
installation of pump group into its place. Incorrect and careless installation causes
early wearing of pump parts and failures.
- Pump ground should be so heavy to absorb vibrations and sturdy to prevent bends
and adjustments defects. Ground concrete should completely be solidified,
completed its plug time and proper stud bolts are placed in pump frame fixing holes
and proper fixing lugs should be placed for using in making connections with welding.
Concrete and plate upper surface should be horizontal and very smooth.
Installation
Installation of pump group to ground by anchoring stud bolts:
- Pump group is placed to center the stud bolt slots which are opened in ground
concrete.
- Anchoring stud bolts are inserted through fixing holes over pump frame fixing holes
and places into their slots.
- Pump group is placed over base concrete. Liquid balance is placed over pump
discharge flange and horizontality of pump is controlled. If there is a horizontal
imbalance in pumps position, steel wedges are put under frame and balance of pump
group is obtained.
