3. Product description
3.1 Purpose of use
The unit GMK-A is designed for the delivery of lube oils as of 150 mm²/s
or for the delivery of lube greases from NLGI class 000 up to NLGI class
2 exclusively.
Different viscosity classes are possible, but this requires careful verify-
cation. Therefore, please contact WOERNER if you wish to operate the
unit with lubricants other than those described above.
3.2 Limits of use
The application area of the pump unit’s components is restricted as follows:
Temperature range:
+
10 … +80 °C
The device can also be used at lower temperatures, but this requires careful verification in
combination with the desired medium. Therefore, please contact WOERNER if you wish to
operate the device in a temperature range other than that described above.
The lifetime is 50,000 strokes, regardless of the number of outlets used.
Depending on the version, these limits of use may be restricted further. Such further restric-
tions are dealt with in this operation manual later on.
Besides, the unit’s area of application is determined by the medium to be delivered. Hence,
when determining the area of application, you also need to refer to the technical data sheets
for the medium to be used.
3.3 Ambient conditions
Unit operation in an aggressive atmosphere (solvent vapours, acids,
lyes, salt water mist, etc.) may cause damage to or corrosion of compo-
nents and, thus, failure of the system and endangerment due to leaking
lubricant!
Ambient temperature range
Lower temperature limit:
+10 °C
Upper temperature limit:
+80 °C
Relative humidity:
max. 70%
Noise level:
<70 dB(A)
Physical environment
In heights as of 1.000 metres above sea level, the system should be operated after consul-
tation with the manufacturer only.
