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, ushing ow must be provided
through port M14 located on the EDC, FNR and NFPE 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 lled with hydraulic uid.
Recommended mounting for a multiple pump stack is to arrange the highest
power ow towards the input source.
Consult Sauer-Danfoss for nonconformance to these guidelines.
Will be inlet pressure with internal charge pump. For reference see operating
parameter on next page. Will be case pressure with external charge supply.
Please verify mating pump shaft seal capability.

H1 Axial Piston Pump, Size 045/053, Single
Technical Information
General Technical Specications
Shaft Loads External radial shaft loads
H1 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 Sauer-Danfoss representative.
The maximum allowable radial load (Re) is based on the maximum external moment
(Me) and the distance (L) from the mounting ange to the load. It may be determined
using the following table and formula.
Re = Me / L

All external shaft loads aect bearing life. In applications with external shaft loads,
minimize the impact by positioning the load at 0° or 180° as shown in the gure.
Sauer-Danfoss recommends clamp-type couplings for applications with radial shaft
loads.
Contact your Sauer-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.

Electrical Displacement Control (EDC) Options A2 (12 V)/A3 (24 V)
Pump displacement vs. control current
EDC Principle
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. Dierential 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
H1 controls are available with optional control passage orices to assist in matching
the rate of swashplate response to the application requirements (e.g. in the event of
electrical failure). Software ramp or rate limiting should be used to control vehicle
response in normal operation. The time required for the pump output ow to change
from zero to full ow (acceleration) or full ow to zero (deceleration) is a net function of
spool porting, orices, 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 software and orice selection for the desired response.
H1 pumps are limited in mechanical oricing combinations. Software is envisioned
as the means to control the swashplate response in normal operating conditions.
Mechanical servo orices are to be used only for fail-safe return to neutral in the event of
an electrical failure.
Typical response times shown below at the following conditions:
∆p = 250 bar [3626 psi]
Viscosity and temperature = 30 mm2/s (50 °C) [141 SUS (122 °F)]
Charge pressure = 20 bar [290 psi]
Speed = 1800 min-1 (rpm)

General Technical Specications
Forward-Neutral-Reverse (FNR) Electric Control Options A9 (12 V)/B1 (24 V)
Pump displacement vs. electrical signal
The 3-Position (F-N-R) control uses an
electric input signal to switch the pump
to a full stroke position.
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.
