®
Special seals may require different auxiliary piping to that described above. Consult separate User Instructions and or Flowserve if unsure of correct method or arrangement.
For pumping hot liquids, to avoid seal damage, it is recommended that any external flush/cooling supply be continued after stopping the pump.
4.5.6 Final checks
Check the tightness of all bolts in the suction and discharge pipework. Check also the tightness of all foundation bolts.
4.6 Final shaft alignment check
After connecting piping to the pump, rotate the shaft several times by hand to ensure there is no binding and all parts are free.
Recheck the coupling alignment, as previously described, to ensure no pipe strain. If pipe strain exists, correct piping.
4.7 Electrical connections
Electrical connections must be made by a qualified Electrician in accordance with relevant local, national and international regulations.
It is important to be aware of the EUROPEAN DIRECTIVE on potentially explosive areas where compliance with
It is important to be aware of the EUROPEAN DIRECTIVE on electromagnetic compatibility when wiring up and installing equipment on site. Attention must be paid to ensure that the techniques used during wiring/installation do not increase electromagnetic emissions or decrease the electromagnetic immunity of the equipment, wiring or any connected devices. If in any doubt contact Flowserve for advice.
The motor must be wired up in accordance with the motor manufacturer's instructions (normally supplied within the terminal box) including any temperature, earth leakage, current and other protective devices as appropriate. The identification nameplate should be checked to ensure the power supply is appropriate.
A device to provide emergency stopping must be fitted.
If not supplied
For electrical details on pump sets with controllers see the separate wiring diagram.
See section 5.3, Direction of rotation before connecting the motor to the electrical supply.
4.8 Protection systems
The following protection systems are recommended particularly if the pump is installed in a potentially explosive area or is handling a hazardous liquid. If in doubt consult Flowserve.
If there is any possibility of the system allowing the pump to run against a closed valve or below minimum continuous safe flow a protection device should be installed to ensure the temperature of the liquid does not rise to an unsafe level.
If there are any circumstances in which the system can allow the pump to run dry, or start up empty, a power monitor should be fitted to stop the pump or prevent it from being started. This is particularly relevant if the pump is handling a flammable liquid.
If leakage of product from the pump or its associated sealing system can cause a hazard it is recommended that an appropriate leakage detection system is installed.
To prevent excessive surface temperatures at bearings it is recommended that temperature or vibration monitoring are carried out. See sections 5.7.4 and 5.7.5.
5COMMISSIONING, START-UP, OPERATION AND SHUTDOWN
These operations must be carried out by fully qualified personnel.
5.1 Pre-commissioning procedure
Pumps and electric motors are supplied
Other drivers and gearboxes, if appropriate, should be lubricated in accordance with their manuals.
