8 Storage, preservation
This section provides information about the correct storage and preservation of
internal gear pumps for long-term storage.
8.1 Storage
The packaging is only intended for shipment and short-term storage.
Please note the following in the event of long-term storage:
•
Store the internal gear pumps in dry, frost-free rooms with minimum temperature
uctuations. The relative humidity must be a maximum of 70%.
•
Store pumps on suitable shelves with sufcient space for checks and followup
treatment (for example, anticorrosion agents).
•
Check metallic blank parts (drive shafts, ange seal surfaces) every six weeks for
corrosion, if necessary, treat with anticorrosion agents (e.g. “Tectyl 511”).
• After 18 months of storage, the pump must be checked by a trained expert or by
Voith Turbo H + L Hydraulic before installation (aging process of the valve seals).
8.2 Preservation
Specify the storage time on the pump purchase order!
The following storage times are possible.
Storage up to one year
Series internal gear pumps can be stored for up to one year after delivery without
requiring any special measures.
Prerequisite: The pressure and suction ports of the pump must be sealed with
sealing plugs.
Storage up to two years
The pump is sprayed with Tectyl, and then shrink-wrapped in a plastic sleeve after
adding drying agents (e.g. kieselgur padding or similar). This protection lasts for two
years.
Storage up to four years
The item is also rinsed with a low-viscosity hydraulic oil, for example ISO VG 22,
before being sprayed and shrinkwrapped in plastic.
