Recommended
installation position
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.
Auxiliary cavity pressure
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.

Technical Information
General Technical Specications
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
Me= Shaft moment
L= Flange distance
Re = External force to the shaft
Radial load position

Loads
All external shaft loads aect 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.

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. Dierential 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 orices 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

H1 controls are available with optional control passage orices to assist in matching

Non Feedback
Proportional Electric
Control (NFPE)
Options A8 (12 V) /
B8 (24 V)
The Non Feedback Proportional Electric
(NFPE) control is an electrical automotive
control in which an electrical input
signal activates one of two proportional
solenoids that port charge pressure to
either side of the pump servo cylinder.
The NFPE control has no mechanical
feedback mechanism.
The pump displacement is proportional
to the solenoid signal current, but it also
depends upon pump input speed and
system pressure. This characteristic also
provides a power limiting function by
reducing the pump swashplate angle
as system pressure increases. A typical
response characteristic is shown in the
accompanying graph.
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.

All controls are available with a Manual Over Ride (MOR) either standard or as an option
for temporary actuation of the control to aid in diagnostics.
Forward-Neutral-Reverse (FNR) and Non Feedback Proportional Electric (NFPE) controls
are always supplied with MOR functionality.
Unintended MOR operation will cause the pump to go into stroke. The vehicle or device
must always be in a „safe“ condition (i.e. vehicle lifted o the ground) when using the
MOR function. The MOR plunger has a 4 mm diameter and must be manually depressed
to be engaged. Depressing the plunger mechanically moves the control spool which
allows the pump to go on stroke. The MOR should be engaged anticipating a full stroke
response from the pump.
Warning
An o-ring seal is used to seal the MOR plunger where initial actuation of the function will
require a force of 45 N to engage the plunger. Additional actuations typically require
less force to engage the MOR plunger. Proportional control of the pump using the MOR
should not be expected.
Refer to control owtable for the relationship of solenoid to direction of ow.
