1)
The maximum permissable values of your pump unit can be found in chapter 11.5.
2)
The volume flow is dependend on the viscosity of the lubricant, operating pressure and
pump rotation.
Besides, the pump 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
Pump unit operation in an aggressive atmosphere (solvent vapours,
acids, lyes, salt water mist, etc.) may cause damage to or corrosion of
components and, thus, failure of the system and endangerment due to
leaking lubricant!
