8. Enclosure protection IP 68

Definition According to EN 60529, the conditions for meeting the requirements of

enclosure protection IP 68 are to be agreed between manufacturer and
user.
AUMA gearboxes in enclosure protection IP 68 fulfil the following require

-

ments in compliance with AUMA definitions:

.

Head of water max. 6 m.

If submersed in other media, additional measures for corrosion protection
ma

y be necessary; please consult AUMA. Submersion in aggressive media,

e.g. acids or alkaline solutions, is not permitted.

Inspection AUMA gearboxes in enclosure protection IP 68 undergo a routine testing for

tightness in the factory.

After submersion

.

Check gearbox.

.

In case of ingress of water, dry actuator correctly and check for proper
function.

Notes

.

The enclosure protection IP 68 refers to the interior of the gearbox.

.

If the gearboxes are likely to be repeatedly submersed, a higher corrosion
protection KS or KX is required.

.

We strongly recommend to select the higher corrosion protection KS or
KX for gearboxes for buried service.

.

Use suitable sealing material between valve flange and gearbox.

.

Stem protection tubes and telescopic protection tubes should not be used
during submersion, instead use a screw plug made of aluminium.

.

When using output drive types A and AF (stem nut), it cannot be
prevented that during submersion water enters the bore of the hollow shaft
along the thread of the valve stem. This leads to corrosion. The water also
enters the thrust bearings of output drive type A, causing corrosion and
damage of the bearings. The output drive types A and AF should therefore
not be used for gearboxes in enclosure protection IP 68.

.

For submersion in water, AUMA recommends to use grease suitable for
use in drinking water.

.

For continuous submersion, the seals should be changed at shorter inter­vals.

Spur gearboxes GST 10.1 – GST 40.1 Operation instructions

9. Maintenance

9.1 General references After commissioning, check gearbox for damage to paint finish.

Do a thorough touch-up to prevent corrosion.
Original paint in small quantities can be supplied by AUMA.

AUMA gearboxes require only very little maintenance.
To ensure that the gearbox is always ready to operate, we recommend –
provided that on an average not more than 10 operations are performed per
year – the following measures:

.

Approximately six months after commissioning and then every year check
screws between multi-turn actuator, gearbox, and valve for tightness. If
required, tighten applying the torques given in table 2 (page 8).

.

Perform a test run as well as a visual inspection for grease leakage every
six months.

.

Carry out a detailed functional test for each gearbox every 5 years.
Record the results for future reference.

.

For gearboxes permanently exposed to ambient temperatures above
40 °C, maintenance must be performed at shorter intervals.

.

For gearboxes with output drive type A: at intervals of approx. six months
from commissioning, press in Lithium soap EP multi-purpose grease on
mineral oil base at the grease nipple with grease gun (for quantity, refer to
table 3, page 10).

Seals:

The seals m

ust be changed when changing the grease.

Seal kits may be obtained from AUMA.

Grease:

A grease and seal change is recommended after the following operation
times:

.

if operated seldom, after 10 – 12 years

.

if operated frequently, after 6 – 8 years

.

Only original AUMA grease must be used.

.

For the grease type, refer to the name plate: Standard F1

.

Lubricants should not be mixed.

The removed lubricant and the cleaning agent used must be
disposed of accor

ding to the relevant regulations.

For safe operation of explosion-proof products, the gear
housing has to be lubricated in compliance with the
manuacturer specifications. In the event of lubricant loss,
repair measures habe to be initiated without delay.

10. Disposal and recycling

AUMA gearboxes have an extremely long lifetime. However, they have to be
replaced at one point in time.
Our gearboxes have a modular design and may therefore easily be disas

-

sembled, separated and sorted according to materials, i.e.:

.

various metals

.

plastics

.

greases and oils

The following generally applies:

.

Collect greases and oils during disassembly. As a rule, these substances
are hazardous to water and must not be released into the environment.

.

Arrange for controlled waste disposal of the disassembled material or for
separate recycling according to materials.

.

Observe the national regulations for waste disposal.

11. Service AUMA offers extensive services such as maintenance and inspection for

gearboxes. Addresses of AUMA offices and representatives can be found on
page 22 and on the Internet (www.auma.com).
