H1T 045/053/060/068 Axial Piston Tandem Pumps
Technical Specifications
H1 Pumps General Specification
Axial piston closed circuit variable displacement pumps of cradle swash-plate design with clockwise orcounterclockwise direction of rotation.
Pipe connections•••

Main pressure ports H1P 045/053: SAE straight thread O-ring boss
Main pressure ports H1P 060/068: 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 orat 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.

External radial shaft loads H1 Tandem
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 theunit. External radial shaft loads impact lifetime. For lifetime calculations please contact 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.

Re =It may be determined using the following formula:

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 pumpswashplate is positioned on one side of center all or most of the time.

Case drain
The tandem housings are connected through the center section via a drilled hole. The charge relief valve
discharges oil into the front housing. In order to provide positive flow through both housings, use of therear housing case drain is required. The front housing case pressure ports should only be used if thepump is used as a common drain manifold for the vehicle where external drain flow is brought into therear housing and discharged out the front.
The allowable case pressures must be met accordingly.

H1T 045/053/060/068 Axial Piston Tandem Pumps
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 athree-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 acrossthe 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 tostay at some displacement.

Technical Information
H1T 045/053/060/068 Axial Piston Tandem 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 aporting 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 pumpdisplacement between no flow and full flow into opposite directions.
Under some circumstances, such as contamination, the control spool could stick and cause the pump tostay at some displacement.
For the MDC with CCO option the brake port (X7) provides charge pressure when the coil is energized toactivate 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.

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 mechanicalactuation. 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 toneutral 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.

H1T 045/053/060/068 Axial Piston Tandem Pumps
Control Options•••

Customers must install some support to limit the setting range of their Bowden cable to avoid anoverload of the MDC.
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 betransferred from the pilot control to the second control. The kinematic of the linkages must ensurethat either control shaft is protected from torque overload.

C Caution
Using the internal spring force on the input shaft is not an appropriate way to return the customer
connection linkage to neutral, or to force a Bowden cable or a joystick back to neutral position. It is notapplicable for any limitation of the Bowden cable stroke, except the applied torque to the shaft will neverexceed 20 N•m.

Feedback from swash plate.
The MOR plunger has a 4 mm diameter and must be manually depressed to be engaged. Depressing theplunger 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.
An o-ring seal is used to seal the MOR plunger where initial actuation of the function will require a forceof 45 N to engage the plunger. Additional actuation typically require less force to engage the MOR
plunger.
Proportional control of the pump using the MOR should not be expected.

W Warning
Unintended MOR operation will cause the pump to go into stroke; example: vehicle lifted off the ground.
The vehicle or device must always be in a safe condition when using the MOR function.

Swashplate angle sensor for EDC controls
The angle sensor detects the swash plate position with an accuracy dependent upon the calibration
effort done for the application and direction of rotation from the neutral position. At minimum the sensor
can be used for forward, neutral and reverse (FNR) detection.
The sensor works on the hall-effect technology. The implemented technology is based on ameasurement of the magnetic field direction in parallel to the chip surface. This field direction isconverted to a voltage signal at the output.
Enhanced calibration of the non-linear behavior leads to more exact calculation of the pump swashplateangle. The 4-pin DEUTSCH connector is part of the sensor housing. The swashplate angle sensor isavailable for all EDC controls for 12 V and 24 V.

Technical Information
H1T 045/053/060/068 Axial Piston Tandem Pumps
Control Options
Control-Cut-Off (CCO) and Brake Release Valves
The H1 tandem pumps offer an optional Control-Cut-Off valve integrated into the pump center section
and a separate brake release valve allowing the controls to be activated before activating any auxiliary
functions.
The CCO valve shunts charge pressure from the pump controls allowing the servo springs to de-stroke
both pumps. The valve is normally open for fail-safe operation. The solenoid must be energized for thepump to operate. When the machine control circuits energize the CCO solenoid, it connects charge
supply from the charge gallery to the pump controls.
The 045/053 tandem also supplies charge pressure to the port X7 for auxiliary operation of devices suchas spring applied/pressure released brakes. The control cut off valve also shunts pressure away from port
X7.
The 060/068 tandem offers a separate brake release valve that operates independently of the CCO valve
allowing the controls to be activated before activating any auxiliary functions. When the 60/68 brake
valve is deactivated the X7 port shunts to case.

Displacement Limiter
H1 pumps are designed with optional mechanical displacement (stroke) limiters factory set to max.
displacement. The maximum displacement of the pump can be set independently for forward andreverse using the two adjustment screws to mechanically limit the travel of the servo piston down to 50%
displacement.
Adjustments under operating conditions may cause leakage. The adjustment screw can be completely
removed from the threaded bore if backed out to far.
