safety: to order original spare parts, contact M PUMPS PROCESS referring to the model of the pump,
employee number, description of the component and the quantity needed.
When you see elements with rust, cracks, etc, you must perform all replacements/repairs necessary to
re-establish the conditions of the pump safe working. In any case you should always ask an opinion M
PUMPS PROCESS before any intervention.

The
periodic
MAINTENANCE"
To allow a smooth running for a long time is necessary to make the required maintenance.
Operators should make frequent visual inspections to check that the pump is running smoothly without
noise or vibration, and that the discharge pressure is holding steady, without fluctuation, at the correct
figure. Over-heating of the pump or motor bearings is cause for alarm. The bearing housing should not
be more than 50°C above ambient temperature, nor should it exceed 80°C (too hot to touch) in any
event. If the bearings overheat, shut the pump down immediately, investigate the cause, and take
corrective action.
Pump disassembling
22.1.
If the pump has pumped hot liquids, make sure that it has been cooled before disassembly. The pump
may have pumped liquid hazardous to health is therefore necessary to wear personal protective
equipment.
Before to proceed with disassembling, follow carefully the decommissioning instructions, at paragraph
20.2.
The activities of disassembly and maintenance of the pump should be conducted in full compliance with
current health and safety regulations. Some spare parts may have potential health risk to the operators:
DANGER
Refer to Safety paragraph of the present manual prior to start any maintenance
activity.
CAUTION
M PUMPS PROCESS disclaims any liability for damage to property and people and
will invalidate the warranty if you install non original.
Please refer to following cross section for part numbers and relative identification.
Before to disassemble the pump assembly, the pump must be isolated from the system closing suction
and discharge plant valves, drained of liquid and cooled, if pump is handling hot liquid.
Before attempting any maintenance work on pumps in vacuum service, the pumps must be isolated from
suction and discharge system then carefully vented balance pressure in pump casing to atmospheric
pressure.
Remove the pipe plug(s) from the top of the bearing housing(s) and check to see that oil rings are riding
free on the pump shaft and are not hung up.
CAUTION
Failure to observe this caution could result in damage to or destruction of
