Caution
The handling brackets are not rated for any duty other than lifting the pump and the factory supplied
wires and sensors. The brackets are not rated to lift any hoses or pipes that may be attached to the pump
during installation. Handling brackets on the endcap must not be removed under any circumstance.
If the pump needs to be temporarily stored outside the application or the provided packaging, we
recommend resting the pump vertically (shaft pointing downwards) on the SAE C flange. Stable spacers
are required to avoid contact with the input shaft. It is also possible to rest the pump horizontally, using
cast features of the pump as supports. Suitable spacers must be used to avoid any contact with the coils,
sensors and wiring harnesses of the pump.

Caution
Ensure no load is applied to coils, sensors, or wiring when placing the pump on a surface for storage as
these may become damaged.
The packaging supplied with the pump provides a stable storage method with the shaft pointing
downwards and held in place by the box's lid to avoid any movement during transport. The controller
and other accessories provided will be in a different compartment of the box. All elements will be
protected against corrosion and reasonable handling shocks. This packaging is suitable for storage.
The storage area must be free from corrosive materials and gasses. The storage area must be dry (5-60%
relative humidity, non-condensing). The ideal temperature for storage is between 5°C and 40°C.
After removing a pump from storage, check over the unit for visible damage to any of the wiring or
sensors.
If the pump must be stored for long periods or in a humid environment (relative humidity > 60%), seal
the parts in airtight bags with desiccant sachets and use VCI materials to protect the hydraulic items.
Store the controller in an antistatic bag, ideally in the same packaging as shipped.
The installation locations and position of the pump must be as described in this document. Adhere to all
limits specified in the DDP096 pump specifications section regarding pressure, temperature, viscosity
and cleanliness of the hydraulic fluid. Other configurations are possible; please contact your Danfoss
representative for direction.
Pump arrangement
It is recommended to install the pump in a below-oil level and horizontal or near-horizontal shaft
position. This is the location the pump is installed outside of the tank and below the minimum level of
fluid in the tank or inside the tank with sufficient fluid above. Other arrangements are possible, for which
care must be taken to bleed the pump case.

reversals increasing the risk of fretting corrosion at the input shaft interface. It is required to take great
care in shaft coupling interface to increase operating life.
Flooded input shaft installation provides good corrosion protection. For dry shaft installation, a greased
clamped coupling is recommended. If clamped coupling is not possible, care must be taken to reduce the
risk of shaft interface damage. Application of specific anti-corrosion grease is required in this case and
should be regularly maintained. For information on lubrication of spline shafts, refer to
