6 STORAGE AND DISPOSAL
6.1 Storage
If the pump is stored in an environment with an ambient temperature below -6°F (14°C), drain the oil from the pump:
use the procedures in
Section 5.7 and 5.8 , then refit the oil drain-plug to the pump before you store it.
Use the following procedure to store the pump:
1. Ensure that the pump has been purged and shut down as described in Section 4.4 . Disconnect the pump from the
electrical supply.
2. Refer to Figure 1 . Place a suitable container under the cooling-water connections (2 and 32), then remove your
cooling-water supply and return pipelines from the connections and allow the cooling-water to drain from the
pump.
3. Disconnect the shaft-seals purge air or nitrogen supply from the shaft-seals purge inlet (31). If fitted, disconnect
the gas-ballast nitrogen supply from the gas-ballast system.
4. Disconnect the pump inlet (6) and outlet (13) from your process and exhaust pipelines.
5. Fit blanking-plates to the pump-inlet (6) and pump-outlet (13). Place protective covers over the pump services
connection points.
6. Store the pump in cool dry conditions until it is required for use. When required, prepare and install the pump as
described in Section 3 "Installation". If the pump will be subjected to temperatures below freezing then the
water jacket must either be drained or have anti-freeze added to it.
6.2 Disposal
Dispose of the pump, cleaning solution, deposits removed from the pump, used pump oil, grease and any components
safely in accordance with all local and national safety and environmental requirements.
WARNING
Care must be taken to disassemble a pump or to dispose of used components. In particular, care
should be taken with fluoro-elastomer products (e.g. seals) which may have decomposed as the
result of being subjected to high temperatures and components and oil which have been
contaminated with dangerous process substances.
