H1 Pump General Specification
Design Axial piston pump of cradle swashplate design with variable displacement
Direction of rotation Clockwise, Counterclockwise
Pipe connections Main pressure ports: ISO split flange boss
Remaining ports: SAE straight thread O-ring boss
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, flushing flow 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 filled with hydraulic fluid.
Recommended mounting for a multiple pump stack is to arrange the highest power flow towards the input source.
Consult Danfoss for nonconformance to these guidelines.
Auxiliary cavity pressure Will be inlet pressure with internal charge pump. For reference see H1P 115/130 Operating Parameters.
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 your Danfoss
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:
Re= Me
L
Radial load position

L

Me= shaft moment
L= flange distance
Re= external force to the shaft
Thrust loads should be avoided. Contact your Danfoss representative in the event thrust loads are
anticipated.

External radial moment Unit Size 115 Size 130
MeN•m [lbf•in] 129 [1140] 129 [1140]
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.

Charge Pump Selection
In most applications a general guideline is that the charge pump displacement should be at least 10% of
the total displacement of all components in the system. Unusual application conditions may require a
more detailed review of charge flow requirements. System features and conditions which may invalidate
the 10% guideline include (but are not limited to):
•Continuous operation at low input speeds < 1500 min-1 (rpm)
•High shock loading and/or long loop lines
•High flushing flow requirements
•Multiple low speed high torque motors
•High input shaft speeds
Contact your Danfoss representative for application assistance if your application includes any of these
conditions.

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
H1 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.
H1 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.
Typical response times at the following conditions:
∆p 250 bar [3626 psi]
Viscosity and temperature 30 mm²/s [141 SUS] and 50 °C [122 °F]
Charge pressure 20 bar [290 psi]
Speed 1800 min-1 (rpm)
EDC Response Time
Stroking direction 0.8 mm [0.03 in] orifice 1.3 mm [0.05 in] orifice No orifice
Neutral to full flow 4.4 s 1.95 s 1.0 s
Full flow to neutral 2.9 s 1.3 s 0.8 s

Manual Displacement Control (MDC)
A Manual proportional Displacement Control (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.
