3.9 Fill the pump with fluid
3.9.1 Safety of vapour pump fluids
Vapour pump fluids are not dangerous when used in a pump that is operated correctly. But if the pump
is operated incorrectly and is allowed to get to very high temperatures, the pump fluid can go through a
process of thermal breakdown. The breakdown products which result can be dangerous.
Table 13 gives more information about the thermal breakdown of the different vapour pump fluids.
Thermal breakdown is more likely to occur if the breakdown temperature is close to the operating
temperature of your pump.
Ensure that you comply with the following general safety recommendations when you handle or use
vapour pump fluids:
• Store pump fluids away from heat and naked flames.
• Keep fluid containers closed when not in use.
• Prevent spills and minimise operations that will contaminate the working areas and equipment.
• Use suitable absorbent materials to mop up small spills, and dispose of the materials as described
in Section 6.2.
• Keep eyewash bottles filled with water readily available. Use these bottles to immediately flush the
eyes if contaminated with pump fluid.
• Minimise exposure to the pump fluid. Wear suitable protective clothing, such as impervious gloves,
apron, boots and so on. Avoid prolonged and repeated contact with pump fluid.
• Do not put on heavily contaminated items of clothing or protective equipment until they have been
laundered or decontaminated.
• Wash your hands with soap and water before eating or smoking, before using toilet facilities and
before leaving work.
3.9.2 Recommended pump fluids
The thermal breakdown products of some fluids can be dangerous; details of the breakdown products
are given in Table 13. Choose the best fluid for your application.
Note that a cooling-fail thermal snap-switch accessory is available for all EO pumps, to prevent the pump
from overheating if the cooling-water supply fails (refer to Section 1.6).
WARNING
Do not use perfluoropolyether (PFPE) pump fluids in the EO pump. The thermal
breakdown temperature of PFPE fluids is near to the operating temperature of the pump.
The thermal breakdown products of PFPE fluids are very dangerous.
