Pump installation position is discretionary, however the recommended control position is on the top or at the side
with the top position preferred. If the pump is installed with the control at the bottom, flushing flow must be
provided through port M14 located on the EDC or MDC control.
Vertical input shaft installation is acceptable. If input shaft is at the top 1 bar case pressure must be maintained
during operation.
The housing must always be filled with hydraulic fluid. Recommended mounting for a multiple pump stack is to
arrange the highest power flow towards the input source.
Consult Danfoss Power Solutions for nonconformance to these guidelines.
Will be inlet pressure with internal charge pump, see Operating parameters T1P 069/089 on page 5.
Will be case pressure with external charge supply. Please verify mating pump shaft seal capability.

External radial shaft loads
The pumps are designed with bearings that can accept some external radial loads. The external radial
shaft load limits are a function of the load position and orientation, and the operating conditions of the
unit. External radial shaft loads impact lifetime. For lifetime calculations please contact Danfoss Power
Solutions representative.
The maximum allowable radial load (Re) is based on the maximum external moment (Me) and the
distance (L) from the mounting flange to the load. It may be determined using the following formula:
Radial load position
22/18/13
β
= 75 (β10 ≥ 10)
15-20
β
= 75 (β10 ≥ 2)
35-45
100 – 125 µm
Me = shaft moment
L = flange distance
Re = external force to the shaft
Thrust loads should be avoided. Contact factory in the event thrust loads are anticipated.

All external shaft loads affect bearing life. In applications with external shaft loads, minimize the impact
by positioning the load at 0° or 180° as shown in the figure. Danfoss recommends clamp-type couplings
for applications with radial shaft loads.
Contact your Danfoss representative for an evaluation of unit bearing life if you have continuously
applied external loads exceeding 25 % of the maximum allowable radial load (Re) or the pump
swashplate is positioned on one side of center all or most of the time.

Control options
Electrical Displacement Control (EDC)
The Electrical Displacement Control (EDC) consists of a pair of proportional solenoids on each side of a
three-position, four-way porting spool. The proportional solenoid applies a force input to the spool,
which ports hydraulic pressure to either side of a double acting servo piston. Differential pressure across
the servo piston rotates the swashplate, changing the pump‘s displacement from full displacement in
one direction to full displacement in the opposite direction.
Under some circumstances, such as contamination, the control spool could stick and cause the pump to
stay at some displacement. A serviceable 125 μm screen is located in the supply line immediately before
the control porting spool.

Control response
Controls are available with optional control passage orifices to assist in matching the rate of swashplate
response to the application requirements (e.g. in the event of electrical failure). The time required for the
pump output flow to change from zero to full flow (acceleration) or full flow to zero (deceleration) is a net
function of spool porting, orifices, and charge pressure. A swashplate response table is available for each
frame indicating available swashplate response times. Testing should be conducted to verify the proper
orifice selection for the desired response.
T1 pumps are limited in mechanical orificing combinations. Mechanical servo orifices are to be used only
for fail-safe return to neutral in the event of an electrical failure.

Manual Displacement Control (MDC)
MDC principle
An MDC is a Manual proportional Displacement Control (MDC). The MDC consists of a handle on top of a
rotary input shaft. The shaft provides an eccentric connection to a feedback link. This link is connected on
its one end with a porting spool. On its other end the link is connected the pumps swashplate.
This design provides a travel feedback without spring. When turning the shaft the spool moves thus
providing hydraulic pressure to either side of a double acting servo piston of the pump.
Differential pressure across the servo piston rotates the swash plate, changing the pump’s displacement.
Simultaneously the swashplate movement is fed back to the control spool providing proportionality
between shaft rotation on the control and swashplate rotation.
The MDC changes the pump displacement between no flow and full flow into opposite directions. Under
some circumstances, such as contamination, the control spool could stick and cause the pump to stay at
some displacement.
A serviceable 125 μm screen is located in the supply line immediately before the control porting spool.
The MDC is sealed by means of a static O-ring between the actuation system and the control block. Its
shaft is sealed by means of a special O-ring which is applied for low friction. The special O-ring is
protected from dust, water and aggressive liquids or gases by means of a special lip seal.
