6.1 Safety information
WARNING:
Allow the pump to cool (so that it is at a safe temperature for skin contact) before
starting maintenance work. Make sure the pump is switched off in case the thermal
overload device restarts the pump.
WARNING:
Obey the safety instructions given below and take note of appropriate precautions.
Failure to do so can cause injury to people and damage to equipment.
▪
A suitably trained and supervised technician must maintain the pump. Obey your
local and national safety requirements.
▪
Ensure that the maintenance technician is familiar with the safety procedures
which relate to the pump-oil and the products processed by the pumping-system.
▪
Isolate the pump and other components in the pumping system from the electrical
supply so that they cannot be operated accidentally.
▪
After maintenance is completed, recheck the pump rotation direction if the
electrical supply has been disconnected.
▪
Do not reuse O-rings and seals if they are damaged.
▪
The pump and its fluid will be contaminated with the process chemicals that have
been pumped during operation. Ensure that the pump is decontaminated before
maintenance and that adequate precautions are taken to protect people from the
effects of dangerous substances if contamination has occurred.
▪
Do not touch or inhale the thermal breakdown products of fluorinated materials
which may be present if the pump has been heated to 260 °C (500 °F) and above.
These breakdown products are very dangerous. Fluorinated materials in the pump
may include oils, greases and seals. The pump may have overheated if it was
misused, if it malfunctioned or if it was in a fire. Our Material Safety Data Sheets
for fluorinated materials used in the pump are available on request: contact us or
your supplier.
▪
Leak-test the system after maintenance work is complete if any vacuum or exhaust
joints were connected or disconnected, seal any leaks found.
6.2 Maintenance plan
The plan shown in details the routine maintenance operations necessary to maintain the
pump in normal use. Instructions for each operation are given in the section shown.
More frequent maintenance may be required if the pump is used to process corrosive or
abrasive gases and vapours, in these circumstances, we recommend you to replace the
pump seals every year. If necessary, adjust the maintenance plan according to
experience.
