6 Storage and disposal
6.1 Storage
CAUTION
If the pump is stored in temperatures close to, or below, 0 °C (32 °F), drain the cooling water from
the pump, or add a suitable anti-freeze to the pump.
6.1.1 Preparation
1. Shutdown the pump as described in Section 4.3.
2. If necessary, disconnect the electrical supply from the pump motor (refer to the Motor Manual
supplied with the RUVAC WA 40000 pump) or disconnect the drive and transmission system from
the pump drive shaft (refer to the manufacturer’s instructions supplied with the transmission
system and/or to Section 3.3.2 ).
3. If necessary, purge your system and the RUVAC WA 40000 pump with dry air, and disconnect the
pump from your system pipelines.
4. Disconnect the cooling water supply pipelines from the pump.
5. Place and secure protective covers over the pump inlet, outlet and services connections.
6. If required, use suitable lifting equipment to move the pump to its storage area: refer to
section
3.2 and section 3.3.1.
7. If the pump is stored for longer than six weeks, refer to the requirements in Section 6.1.2.
8. Store the pump in clean, dry conditions in a well ventilated place that is free from vibration or
shocks.
6.1.2 Long term storage
If the pump is to be stored for longer than six weeks:
1. Drain the oil from the drive end and non-drive end covers: refer to
Section 5.6.
2. Fill the drive end and non-drive end covers with a suitable protective oil (see Table 12): use the
method in Section 5.6.
3. Turn the pump drive shaft by hand through three or four revolutions, to turn the pump and prevent
seizure.
4. Spray a suitable protective oil (see Table 12) through the inlet and into the pump.
5. If required, spray a suitable protective oil (see Table 12) on the outer machined surfaces of the
pump e.g. inlet and outlet flanges, to inhibit corrosion.
During storage, every 14 days or less, turn the pump drive shaft by hand through a quarter of a
revolution, to turn the pump and prevent seizure or degradation of the bearings. Care should be
taken to ensure the shaft is left in a different position every time.
When required for use after storage:
1. Drain the protective oil from the drive end and non-drive end covers, then fill the end covers with
new oil: refer to Section 5.6 .
2. Use a suitable cleaning solution (such as alcohol or white spirit) to clean the rotors:

Moisten a suitable clean, lint free cloth with the cleaning solution.

Clean the rotors which are visible through the inlet port.

Turn the pump drive shaft as necessary to access the other rotors.
