6 Storage and disposal
6.1 Storage
Note: If you will store the pump in an environment with an ambient temperature below -14 °C (7 °F), you must
also drain the oil from the pump: use the procedure in Section 5.7, then refit the oil drain-plug to the pump
before you store it.
Store the pump as follows:
1. Ensure that the pump has been shut down as described in Section 4.4, then disconnect the pump from the
electrical supply.
2. Refer to Figure 1. Place a suitable container under the cooling-water connections (2, 7), 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 (22). 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 clean dry conditions until required.
7. When required for use, prepare and install the pump as described in Section 3 of this manual.
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.
Take particular care with the following:
Fluoroelastomers which may have decomposed as the result of being subjected to high temperatures.
Components and oil which have been contaminated with dangerous process substances.
Ensure that you wear the appropriate Personal Protective Equipment (PPE) when you handle
contaminated oils or contaminated components.
