Storage Upon Receipt and up to 3 Months:
Pump should stored indoors and out of the weather until ready for installation.
In construction environments where indoor storage is not available, store the pump on blocks or pallets, build a frame
around it and cover with tarpaulin.
o
Frame must be able to withstand snow and wind, anchored and built in a manner to last the entire time pump
is in storage. Shelter must be continuously maintained in a stable and leak free condition.
o
Ensure the tarpaulin does not touch the pump, since this can lead to condensation. Leave the bottom open
for ventilation. Minimum Tarp requirements: 610gsm (18oz) Vinyl, 0.5mm (20mil) thick, Water proof & UV
(ultraviolet) resistant
Storage Exceeding 3 Months
If pump is exposed to the weather at any time the frame requirements still stand.
The Wet End pump parts should be drained and isolated from reaction vessel gasses.
Check the rust inhibitor coatings on bare metal surfaces and renew exposed areas.
Check the painted surfaces for any signs of corrosion or breaks in the coatings and touch-up as needed.
Check that the threaded holes are protected with grease and plugged.
Oil lubricated bearing assemblies with GIW Blue Oil (requires shaft rotation):
o
GIW Blue Oil supplied with the pump should be added to the bearing housing until the level is halfway of the
Oil Sight Glass (642).
o
Pump shaft should be manually rotated approximately 5 turns each month to keep the bearings coated.
o
Vertical pumps should have the Lubrication Oil System running while the shaft is rotated 5 turns each month.
o
The oil should be replaced if shutdown duration exceeds 12 months.
Oil lubricated bearing assemblies with GIW Storage Oil (alternative to shaft rotation):
o
GIW Storage Oil should be added to the bearing housing until the level is halfway of the Oil Sight Glass (642)
and rotate the shaft several times. No further shaft rotation is needed
o
The bearing assembly must remain sealed in the factory assembled condition. The oil fill plug must be securely
replaced and no breather or other vent added to the bearing housing.
o
Vertical pumps should be stored horizontally and filled with Storage Oil to the center of the sight glass or
25mm (1 inch) below the largest diameter Inpro/Seal bearing isolator, whichever is lower.
o
The storage oil should be replaced if shutdown duration exceeds 12 months.
Grease lubricated bearing assemblies do not require monthly rotation.
If the pump is fitted with a mechanical seal, precautions may need to be taken before rotating the shaft. Refer to the
seal manufacturer’s maintenance manual for instructions.
Pumps with InPro/Seal® bearing isolators must be coated externally with white grease or petroleum jelly to seal the
gap between the rotor and stator. Units equipped with a vent kit must have the vents either removed and plugged, or
blocked to prevent air exchange.
Vertical pumps should be stored horizontally, and the blocking on the shaft should be left in place until the pump is
ready to be installed.
Storage Exceeding 12 Months (Long Term Storage)
The following information on long term storage pertains to GIW pump assemblies only and does NOT cover any auxiliary
equipment such as motors, gearboxes, lube oil systems, etc... Long term storage for auxiliary equipment must be included in
the contract and negotiated with sub-vendors at time of order.
At 12 months storage and again at 24 months of storage, the following additional actions should be taken:
Check the rust inhibitor coatings on bare metal surfaces and renew exposed areas.
Check the painted surfaces for any signs of corrosion or breaks in the coatings and touch-up as needed.
Replace the GIW Oil and/or Storage Oil, if applicable.
Installed Spares (Idle Pumps)
After being idle to 1 or more months, shafts must be rotated through five (5) or more revolutions, either manually or by
a short duration start-up. If regularly exposed to moisture (weather or process related), monthly oil analysis is
recommended since idle bearing assemblies are subject to breathing and internal condensation due to ambient
temperature fluctuations.
After being idle for 3 or more months, oil change or oil analysis is recommended for all pumps to ensure against
condensation.
After being idle for 12 months or more, the oil should be replaced.
