General information
ATEX Introduction
The ATEX Directive 2014/34/EU specifies the minimum safety requirements for equipment intended for
use in potentially explosive atmospheres in European Union member states. ATEX is derived from the
French term ATmosphères EXplosives.
Hydraulic pump are designed for mobile and stationary applications. Some pump are used in related
applications, where locations are classified as hazardous areas.
The equipment intended for use in hazardous areas are divided into two groups:
Group I: Equipment intended for use in underground parts of mines (mining equipment).
Group II: Equipment intended for use in other places than mines (non-mining equipment).
The Danfoss hydraulic pump, type D1P are intended for use in Group II applications.
Explosive atmosphere
Explosion triangle
A “hazardous area” is defined as an area in which the atmosphere contains, or may contain in sufficient
quantities, flammable or explosive gases, dusts or vapours. In such an atmosphere a fire or explosion is
possible when three basic conditions are met. This is often referred to as the “hazardous area” or
“explosion” triangle.
An atmosphere with the potential to become an explosive atmosphere during operating conditions
and/or under the influence of the surroundings is defined as a potentially explosive atmosphere.
Products covered by directive 2014/34/EU are defined as intended for use in potentially explosive
atmospheres. Removing one of the elements eliminates all risk of explosion.
General zone classification
Directive 99/92/EC divides the Hazardous areas into zones and defines criteria by which products are
categorized within these zones; Zone 0 / 20 is the most restrictive and Zones 1 / 21 and 2 / 22 are less
restrictive. The following table describes the zones in an installation where there is a potential for
explosive atmospheres. The owner of the installation must analyze and assess the area in which the
explosive gas/dust mixture may occur, and if necessary must divide it into zones. This process of zoning
then allows the correct plant and equipment to be selected for use in the area.

Equipment category and zones
Mechanical components with potential ignition sources e.g. components containing non-conductive
materials or layers or components with hot surface are covered by the ATEX-directive.
Non-mining equipment for potentially explosive atmosphere is classified as:
Equipment Group II – this group comprises three categories according to the level of safety provided:
•
Category 1
•
Category 2
•
Category 3
Category 1 equipment has the highest degree of protection – see the following below.
These products have to fulfil all requirements in the ATEX directive, and have to be marked with the
required “Ex” marking.
Equipment located in zone specified areas must fulfil the following requirements (see also the following
figure):
Category 3 – approved equipment can be installed in hazardous areas zone 2 / 22 and outside zone
•
categorized areas.
Category 2 – approved equipment can be installed in hazardous areas zone 1 / 21, zone 2 / 22 and
•
outside zone categorized areas.

General information
Contents of marking
The rules for the marking of systems, equipment and components are uniformly defined in the standards
relating to the general technical requirements – EN 13463-1 for mechanical equipment.
A priority for all Ex equipment and protective systems is that the marking should show the areas of their
designated use. Components covered within the scope of the ATEX directive have to be CE-marked, and
marked with the specific “Ex”-sign.
Principle
The marking must indicate the following:
•
The manufacturer who has put the item of equipment on the market
•
Manufacturer’s type identification
•
Year in which the equipment was manufactured
•
A serial number
And further the ignition protection marking
•
Symbol of the equipment group and category (M1 or M2 for group I mining equipment, or 1 or 2 or 3
for Group II non-mining equipment).
Additionally for Group II equipment only:
1. The letter “G” where explosive atmospheres caused by gases, vapours or mists are concerned;
and/or
2. The letter “D” where explosive atmospheres caused by dusts are concerned.
•
Type of ignition protection system.
•
Where appropriate, symbol of explosion group of the equipment.
•
For Group II equipment, the symbol indicating the temperature class or the maximum surface
temperature in °C, or both.

Technical Information
ATEX certified D1P 130/145/193/260
Technical specifications
Ambient temperature
Maximum ambient temperature depends on the requested ATEX class needed.
In general the ambient temperature should lie between -30 °C [-22 °F] and +90 °C [+210 °F] to ensure that
the shaft seal retains its sealing capacity.
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.
Ratings and performance data are based on operating with hydraulic fluids containing oxidation, rust
and foam inhibitors. These fluids must possess good thermal and hydrolytic stability to prevent wear,
erosion and corrosion of pump components.
Mineral oils
For systems containing Danfoss hydraulic pumps, type D1P, mineral hydraulic oil with anti-wear
additives, type HLP [DIN 51524] or HM (ISO 11158) must be used. Mineral oils without anti-wear additives
or engine oils can also be used, provided operating conditions are suitable.
Warning
It is compulsory to use oils whose inflammable degree is at least 50K above the maximum surface
temperature of the pump. Maximum surface temperature for Group IIG and IID can be found under:
Viscosity and temperature for D1P pump on page 10.
Oil temperature
Maximum oil temperature depends on the requested ATEX class needed (in this case T3)..
Under normal operating conditions it is recommended to keep the temperature in the range of 30 °C [86
°F] and 60 °C [140 °F].
Fluid temperature affects the viscosity of the fluid and resulting lubricity and film thickness. High
temperatures can also limit seal life, at most non-metallic materials are adversely affected by use at
elevated temperatures.
Fluids may break down or oxidize at high temperature, reducing their lubricity and resulting in reduced
life of the unit. Oil life is greatly reduced if its temperature exceeds +60 °C [+140 °F]. As a general rule, oil
life is halved for each 8 °C [46 °F] its temperature exceeds +60 °C [+140 °F].
Viscosity
Maintain fluid viscosity within the recommended range for maximum efficiency and bearing life.
Minimum viscosity should only occur during brief occasions of maximum ambient temperature and
severe duty cycle operation. Maximum viscosity should only occur at cold start. Limit speeds until the
system warms up.
Fluid viscosity limits
Conditions mm2/s (cSt) SUS
Minimum 12 66
Continuous 20 - 80 98 - 370
Maximum 1500 6950
We recommend the use of an oil type having a viscosity of 35 mm2/s at the actual operating temperature.
