FP USER INSTRUCTIONS ENGLISH 71576286 - 07/06

It is the plant operator's responsibility to ensure that all maintenance, inspection and assembly work is carried out by authorized and qualified personnel who have adequately familiarized themselves with the subject matter by studying this manual in detail (see also section 1.6.2).

Any work on the machine must be performed when it is at a standstill. It is imperative that the procedure for shutting down the machine is followed, as described in section 5.6.

On completion of work all guards and safety devices must be re-installed and made operative again.

Before restarting the machine, the relevant instructions listed in section 5, Commissioning, start up, operation and shut down must be observed.

Oil and grease leaks may make the ground slippery. Machine maintenance must always begin and finish by cleaning the ground and the exterior of the machine.

If platforms, stairs and guardrails are required for maintenance, they must be placed for easy access to areas where maintenance and inspection are to be carried out. The positioning of these accessories must not limit access or hinder the lifting of the part to be serviced.

When air or compressed inert gas is used in the maintenance process, the operator and anyone in the vicinity must be careful and have the appropriate protection. DO NOT SPRAY air or compressed inert gas on skin. DO NOT DIRECT an air or gas jet towards other people. Never use air or compressed inert gas to clean clothes.

Before working on the pump, take measures to prevent an uncontrolled start. Put a warning board on the starting device with the words:

"Machine under repair: do not start".

With electric drive equipment, lock the main switch open and withdraw any fuses. Put a warning board on the fuse box or main switch with the words:

"Machine under repair: do not connect".

Never clean equipment with inflammable solvents or carbon tetrachloride. Protect yourself against toxic fumes when using cleaning agents.

6.2 Maintenance schedule

It is recommended that a maintenance plan and schedule is adopted, in line with these User Instructions. It should include the following:

a)The pump must be completely vented and drained and rendered inert before any disassembly operation.

b)Any auxiliary systems installed must be monitored, if necessary, to ensure they function correctly.

c)During cleaning of the pump ensure the compatibility between the cleaning products and the gaskets.

d)Verify the condition of the gaskets.

e)Gland packings must be adjusted correctly to give visible leakage and concentric alignment of the gland follower to prevent excessive temperature of the packing or follower. Mechanical seals should present no leakage.

f)Check for any leaks from gaskets and seals. The correct functioning of the shaft seal must be checked regularly.

g)Check bearing lubricant level, and if the hours run show a lubricant change is required.

h)Check that the duty condition is in the safe operating range for the pump.

i)Check vibration, noise level and surface temperature at the bearings to confirm satisfactory operation.

j)Check the tightness of the connections.

k)Check dirt and dust is removed from areas around close clearances, bearing housings and motors.

l)Check coupling alignment and re-align if necessary.

m)Verify the correct operation of the system.

The equipment used for maintenance and disassembly in an ATEX zone must be in conformity with the requirements zone.

Our specialist service personnel can help with preventative maintenance records and provide condition monitoring for temperature and vibration to identify the onset of potential problems.

If any problems are found the following sequence of actions should take place:

a)Refer to section 7, Faults; causes and remedies, for fault diagnosis.

b)Ensure equipment complies with the recommendations in this manual.

c)Contact Flowserve if the problem persists.

6.2.1 Standard maintenance

Roller bearing

The bearings fitted are prepacked with grease at the factory. When the regreasing period is reached it is necessary to remove as much of the old grease as possible with a clean lint free cloth and repack the bearings with fresh grease.
