Technical Information
H1P 115/130 Axial Piston Single Pumps
Technical specifications
H1 Pumps General Specification
Axial piston closed circuit variable displacement pump of cradle swash-plate design with clockwise or
counterclockwise direction of rotation.
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.
H1P 115/130 Technical Data
Auxiliary cavity pressure
Auxiliary cavity pressure will be inlet pressure with internal charge pump or case pressure with external
charge supply. For reference see H1P 115/130 Operating Parameters on page 6. Please verify mating
pump shaft seal capability.

Bearing Life and External Radial Shaft Loads
All external shaft loads affect bearing life. 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.
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 swash-plate is positioned on one
side of center all or most of the time.

External radial shaft loads impact lifetime. For lifetime calculations please contact your Danfoss
representative. In applications with external shaft loads, minimize the impact by positioning the load at
0° or 180° as shown below.

Technical Information
H1P 115/130 Axial Piston Single Pumps
Technical specifications
The maximum allowable radial shaft 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:
Thrust loads should be avoided. Contact your Danfoss representative in the event thrust loads are
anticipated.
H1P 115/130 Mounting Flange Loads
The Rated and Shock load moments apply for top or side orientation of control.

Rated moment MR = 5933 N•m [52 510 lbf•in]
Shock load moment MS = 12 640 N•m [ 111 870 lbf•in]

Charge pump
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.

Technical Information
H1P 115/130 Axial Piston Single Pumps
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 swash-plate, changing the pump‘s displacement
from full displacement in one direction to full displacement in the opposite direction. A serviceable 125
μm screen is located in the supply line immediately before the control porting spool.
Under some circumstances, such as contamination, the control spool could stick and cause the pump to
stay at some displacement.

H1 pumps are limited in mechanical orifice combinations. Mechanical servo orifices are to be used only

H1P 115/130 Axial Piston Single Pumps
Control Options
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 swash-plate.
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 swash-plate movement is fed back to the control spool providing proportionality
between shaft rotation on the control and swash-plate 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.

MDC General Information
In difference to other controls the MDC provides a mechanical deadband. This is required to overcome
the tolerances in the mechanical actuation.
The MDC contains an internal end stop to prevent over travel. The restoring moment is appropriate for
turning the MDC input shaft back to neutral only. Any linkages or cables may prevent the MDC from
returning to neutral.
The MDC is designed for a maximum case pressure of 5 bar and a rated case pressure of 3 bar. If the case
pressure exceeds 5 bar there is a risk of an insufficient restoring moment. In addition a high case pressure
can cause the NSS to indicate that the control is not in neutral. High case pressure may cause excessive
wear.
Customers can apply their own handle design but they must care about a robust clamping connection
between their handle and the control shaft and avoid overload of the shaft.
Customers can connect two MDC’s on a tandem unit in such a way that the actuation force will be
transferred from the pilot control to the second control but the kinematic of the linkages must ensure
that either control shaft is protected from torque overload. To avoid an overload of the MDC, customers
must install any support to limit the setting range of the Bowden cable.
Caution
Using the internal spring force on the input shaft is not an appropriate way to return the customer
connection linkage to neutral.
