ATEX technical specifications
The technical specifications in this chapter are supplemental for ATEX systems only. For comprehensive
technical specifications, including maximum pressure rating, maximum flow, etc. please refer to the
standard D1P Technical Information document.
Danfoss does not claim responsibility for the use of the pump in operating conditions not allowed
according to the information shown in this document and the standard D1P Technical Information
document.
Painting or coating can be an electric insulator if a thickness greater than 200 um is applied. The
thickness of the paining of original DPS paint is less than 200 um.

To ensure that the surface temperature will not exceed the allowed value according to the used
temperature class, it is recommended to attach a temperature sensor to the pump in the shown area on
one of the side surfaces near the maximum displacement limiter at the bottom side of the pump.

Oil types / Operating fluids
In a hydraulic system the most important task of the oil is to transfer energy. At the same time the oil
must lubricate moving parts in hydraulic components, protect them from corrosion, and transport dirt
particles and heat out of the system. To ensure that hydraulic components operate without problems
and have long operating life it is therefore vital to select the correct oil type with the necessary additives.
