1.6.6 Pump maintenance
Pump maintenance work must be done when the pump is at a standstill.
Before removing the casings of mobile parts, make sure that the motor cannot be
started again before restoring safety conditions.
The pump must not be under pressure and must be cooled.
Pumps or units which feed substances affecting people's health must be
decontaminated.
Should a pump be disassembled to pump any hazardous fluid, the maintenance
operator must wear all DPI prescribed for handling such a substance.
Shortly after finishing maintenance work, all safety and protection devices must be
applied and set to work again.
Setting the pump to function again after maintenance work must be carried out following
the instructions set out in sect. 7.
1.6.7 Non-compliance with the instructions included in this manual
If the instructions included in this manual are not complied with, this may affect people's
health, the environment and the machine.
Such non-compliance may result in:
•
inability to perform any key functions of the pump and/or plant;
•
damage to the pump and/or plant;
•
electric, mechanical and chemical dangers for people;
•
danger for the environment due to leakage of hazardous substances.
1.7 Start-up, operation and maintenance
The plant in which the progressing cavity pump will be applied is not an integrating part
of the supply; therefore, the user must choose the pump which may best fit his needs, as
well as all the accessories needed to ensure the plant safety.
1.8 Safety warning for maintenance, inspection and assembly
The user must make sure that any maintenance, inspection and assembly of
progressing cavity pumps should be carried out by expert technicians. Before starting
work, the staff must have read this manual very carefully.
1.9 Alteration and discretionary production of spare parts
Any alteration or modification of the pump, within the extent of extraordinary maintenance,
are allowed subject to the manufacturer's agreement.
As for ordinary maintenance, original spare parts or any parts deemed to be suitable by
NOVA ROTORS™ S.r.l. must be used.
The use of non-original spare parts leads to the earlier termination of warranty.
