FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06
Avoid mechanical, hydraulic or electrical overload by using motor overload trips or a power monitor and make routine vibration monitoring.
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 shall be fitted.
Carry out the ground connections according to the current local regulations.
To avoid any risk of jamming, the direction of rotation will be checked after priming of the pump (§ 5.3.1, 5.3.2) and before the first start (§ 5.4.2).
4.7 Final shaft alignment check
a)Check the alignment
b)Check by hand that the pump turns freely. A binding indicates a distortion of the pump, which is due to excessive pipes strains. If necessary the pipework design must be
c)If it provided, connect auxiliary pipe systems (hydraulic, pneumatic, sealing system).
d)Control tightness and functionality of auxiliary piping.
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 5.5.4 and 5.5.5.
If a defect of cooling can lead to temperature higher than those acceptable a system of cooling surveillance must be installed.
Except when explicitly required by the customer in the specifications, when a possibility of reverse rotation exists the customer must install a reverse rotation protection device.
The customer must install all equipment required to avoid water hammer.
5COMMISSIONING, START-UP, OPERATION AND SHUTDOWN
These operations must be carried out by fully qualified personnel.
5.1 Direction of rotation
Starting or operating pumps with the wrong direction of rotation can be harmful to the pumps. Ensure that the pump rotation is the same as the arrow on the pump casing. It is preferable to check the direction of rotation before installing the coupling. If not, the pump must be filled in with the liquid before
If maintenance work has been carried out to the site's electricity supply, the direction of rotation should be
5.2 Guarding
Guarding is supplied fitted to the pump set.
If this has been removed or disturbed ensure that all the protective guards around the pump coupling and exposed parts of the shaft are securely fixed.
