6 STORAGE AND DISPOSAL
6.1 Storage
Use the following procedure to store the pump.
1. Place protective covers over the main inlet, side inlet, outlet, interstage (Hi variants only) and vent
ports.
2. Place the pump in its packing materials. For fastest pump-down when the pump is put back into
service, seal the pump inside a plastic bag together with a suitable desiccant.
3. Store the pump in cool, dry conditions until required for use. When required, prepare and install
the pump as described in Section 3.
4. Keep the pump upright at all times to prevent the drainage of oil from the bearing reservoir.
5. Avoid long-term storage if possible. When long-term storage is necessary, the pump should be set
up and run for at least eight hours every six months.
6.2 Disposal
Dispose of the EXT Split Flow Pump and any components and accessories safely in accordance with all
local and national safety and environmental requirements.
Particular care must be taken with any components which have been contaminated with dangerous
process substances.
Take appropriate action to avoid inhalation of any particulates which may be present in the pump. Do
not incinerate the pump. The pump contains phenolic and fluorosilicone materials which can decompose
to very dangerous substances when heated to high temperatures.
WARNING
In the unlikely event of a failure of the pump rotor, dust can be generated from the carbon
fibre reinforced components.
In this event, use appropriate Personal Protective Equipment when handling and disposing
of the pump, and ensure that all pump inlets and outlets are capped off before disposal.
