Technical Information
H1P 045/053 Axial Piston Single Pumps
Technical Specifications
H1 Pumps General Specification
Axial piston closed circuit variable displacement pumps 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.
Auxiliary cavity pressure
Auxiliary cavity pressure will be inlet pressure with internal charge pump or case pressure with external
charge supply. For reference see Operating Parameters. 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.
Radial load position
N•m [lbf•in] TBD
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.

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.

Control Options
Electrical Displacement Control (EDC)
An EDC is a displacement (flow) control. Pump swash plate position is proportional to the input
command and therefore vehicle or load speed (excluding influence of efficiency), is dependent only on
the prime mover speed or motor displacement.
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 170 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.

Control response
H1P 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 swash-plate response times table is available for each frame size. Testing should be conducted to verify
the proper orifice selection for the desired response. Typical response times at the following conditions:
Δ p = 250 bar [3626 psi]
Charge pressure = 20 bar [290 psi]
Viscosity and temperature = 30 mm²/s [141 SUS] and 50 °C [122 °F]
Speed = 1800 min-1 (rpm)

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 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 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.
For the MDC with CCO option the brake port (X7) provides charge pressure when the coil is energized to
activate static function such as a brake release. The X7 port must not be used for any continuous oil
consumption.
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.
Manual Displacement Control Pump displacement vs. control lever rotation
Deadband on B side: a = 3° ±1°
Maximum pump stroke: b = 30° +2/-1°
Required customer end stop: c = 36° ±3°
Internal end stop: d = 40°
MDC operation
The MDC provides a mechanical dead-band required to overcome the tolerances in the mechanical
actuation. The MDC contains an internal end stop to prevent turning the handle into any inappropriate
position.
The MDC provides a permanent restoring moment appropriate for turning the MDC input shaft back to
neutral position only. This is required to take the backlash out of the mechanical connections between
the Bowden cable and the control.
High case pressure may cause excessive wear and the NSS to indicate that the control is not in neutral

position. In addition, if the case pressure exceeds 5 bar there is a risk of an insufficient restoring moment.
The MDC is designed for a maximum case pressure of 5 bar and a rated case pressure of 3 bar.
