3. Product decription
3.1 Purpose
The pump unit DLS-47x/-2C 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 verifycation. Therefore, please contact
DLS Schmiersysteme GmbH if you wish to operate the unit with lubricants other than those
described above.
3.2 Limitation of use
The range of use of the components of the pump unit is limited as follows:
Temperature range: -20 … +60 °C
Permitted discharge pressure: max. 70 bar
The device can also be used at lower temperatures, but this requires careful verication in combination
with the desired medium. Therefore, please contact DLS Schmiersysteme GmbH if you wish to operate
the device in a temperature range other than that described above.
Depending on the version, these limits of use may be restricted further. Such further restrictions 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 Environmental conditions
Unit operation in an aggressive atmosphere (solvent vapours, acids, lyes, saltwater mist, etc.)
may cause damage and/or corrosion of components and thus, failure of the installation as
well as hazards by escaping lubricant!
Ambient temperature range
lower limit temperature: - 20 °C
upper limit temperature: + 60 °C
relative humidity: max. 70%
Noise level: <70 dB(A)
Physical environment
Use of the installation above 1000 m sea level after consultation with the manufacturer only.
