General Information
D1P schematic with charge pump
Basic schematic without control/with charge pump
The charge pump (see schematic) is a circulating pump with which the pump is charged and therefore
can be operated at higher speeds. This also improves cold starting at low temperatures and high viscosity
of the hydraulic fluid. The pressurized reservoir is therefore unnecessary in most cases. A reservoir
pressure of a max. 2 bar is permissible with charge pump.
The values apply at absolute pressure (Pabs) of at least 0.8 bar [11.6psi] at the suction port S and mineral hydraulic fluid.
2
The values apply at absolute pressure (Pabs) of at least 0.6 bar [8.7psi] at the suction port S and mineral hydraulic fluid.
3
The values apply at Vg ≤ Vg max or in case of an increase in the inlet pressure (Pabs) at the suction port S. Please refer to Inlet Pressure vs Speed Graph
Counterclockwise (CCW) & Clockwise (CW) directions as viewed from the shaft end of the pump.
Exceeding the permissible values could cause a loss of function, reduced life or the destruction of the
pump.
Do not exceed the values shown in the table above.

Technical Specifications
D1P 260 angle sensor
Angle sensor principle
The angle sensor option is exclusive to the D1P 260.
The angle sensor option offered in D1P allows users to measure the angle of pump displacement. The
angle sensor is an electronic sensor mounted to the housing of the pump, which reads the pump stroke
angle based on the swashplate position. Interfacing with the angle sensor is achieved through a 4-pin
DEUTSCH DTM04-4P receptacle attached to a flexible connection cable (for a mating connector, use
DEUTSCH plug DTM06-4S). The sensor is mounted to the pump within an aluminum housing to prevent
magnetic interference.
Location
When the input shaft with the control is on the top side, the angle sensor will be viewed on the righthand side. This convention is true for both clockwise and counterclockwise rotation.

Angle sensor calibration
A 2-point calibration of the sensor is recommended, with points measured at pump standby and
maximum pump stroke. Maximum pump stroke can be achieved when the pump input shaft is not being
turned, as D1P pumps are biased to maximum displacement. In some cases, the pump may need to be
turned momentarily to ensure the pump is in the maximum displacement position; this can be achieved
through a momentary switching of the engine starter on/off.
For minimum displacement calibration, the angle sensor can be calibrated by sending the pump to a
standby condition, either high-pressure with a pressure compensator (PC control) or low-pressure with a
flow compensator (LS control). Low-pressure standby is recommended if the control has load sensing or
remote PC functionality. For best results, it is recommended to rotate the prime mover at the highest
operating speed to achieve the lowest angle possible at standby conditions.

Maximum torque ratings are based on shaft strength with no radial force; do not exceed the torque

D1P shaft load
Series D1 pump bearing is capable of accepting external radial and thrust (axial) loads. The external radial
shaft load limits are a function of the load position, orientation, and the operating conditions of the
pump.
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. Compute radial loads using the formula below. D1
pump specifications gives maximum external radial load (Re) and thrust (axial) load (Tin , T
) limits .

D1P mounting flange loads
Me = Re • LL = Distance from mounting flange to point of load
All shaft loads affect bearing life. In applications where external shaft loads cannot be avoided, maximize
bearing life by orienting the load between the 150° and 210° positions, as shown.
Adding auxiliary pumps and/or subjecting pumps to high shock loads may overload the pump mounting
flange. D1 pump specifications gives allowable continuous and shock load moments. Applications with
loads outside allowable limits require additional pump support.
Shock load moment (MS) is the result of an instantaneous jolt to the system.
•
Continuous load moments (MC) are generated by the typical vibratory movement of the application.
•
Me = Maximum external moment
Re = Maximum radial side load
D1P auxiliary mounting pads
Auxiliary mounting pads are available. Since the auxiliary pad operates under case pressure, use an Oring to seal the auxiliary pump mounting flange to the pad. Oil from the main pump case lubricates the
drive coupling.
Applications subject to severe vibratory or shock loading may require additional support to prevent
•
mounting flange damage. The table gives allowable continuous and shock load moments.
D1P estimating overhung load moments
Use the equations below to estimate the overhung load moments for multiple pump mounting. See

Parameters
Understanding and minimizing system noise
Noise is transmitted in fluid power systems in two ways: as fluid borne noise, and structure borne noise.
Fluid-borne noise (pressure ripple or pulsation) is created as pumping elements discharge oil into the
pump outlet. It is affected by the compressibility of the oil, and the pump’s ability to transition pumping
elements from high to low pressure. Pulsations travel through the hydraulic lines at the speed of sound
until there is a change (such as an elbow) in the line. Amplitude varies with overall line length and
position.
Structure borne noise is transmitted wherever the pump casing connects to the rest of the system. The
way system components respond to excitation depends on their size, form, material, and mounting.
System lines and pump mounting can amplify pump noise.
Follow these suggestions to help minimize noise in your application:
Use flexible hoses.
•
Limit system line length.
•
If possible, optimize system line position to minimize noise.
•
If you must use steel plumbing, clamp the lines.
•
If you add additional support, use rubber mounts.
•
Test for resonance in the operating range; if possible avoid them.
•
D1P installation
D1P filtration
Series D1 pumps may be installed in any position. To optimize inlet conditions, install the pump at an
elevation below the minimum reservoir fluid level. Design inlet plumbing to maintain inlet pressure
within prescribed limits (see Inlet pressure limits on D1 pump specifications)
Fill the pump housing and inlet line with clean fluid during installation. Connect the case drain line to the
uppermost drain port (L1, L2 or L3) to keep the housing full during operation.
To allow unrestricted flow to the reservoir, use a dedicated drain line. Connect it below the minimum
reservoir fluid level and as far away from the reservoir outlet as possible. Use plumbing adequate to
maintain case pressure within prescribed limits (see case pressure limits on D1 pump specifications).
To prevent damage to the pump, including premature wear, fluid entering the pump inlet must be free of
contaminants. Series D1 pumps require system filtration capable of maintaining fluid cleanliness at class
20/18/15 according to ISO 4406-1999 or better.
Danfoss Power Solutions does not recommend suction line filtration. Suction line filtration can cause high
inlet vacuum, which limits pump operating speed. Instead we recommend a 125 μm (150 mesh) screen in
the reservoir covering the pump inlet. This protects the pump from coarse particle ingestion.
Return line filtration is the preferred method for open circuit systems. Consider these factors when
selecting a system filter:
Cleanliness specifications
•
Contaminant ingression rates
•
Flow capacity
•
Desired maintenance interval
•
Typically, a filter with a beta ratio of β10 = 10 is adequate. However, because each system is unique, only
a thorough testing and evaluation program can fully validate the filtration system.
For more information, see Danfoss Power Solutions publication BC152886482150Design Guidelines for
Hydraulic Fluid Cleanliness.
D1 High Power Open Circuit Pumps Size 130/145/193/260
Parameters
Reservoir
The reservoir provides clean fluid, dissipates heat, and removes entrained air from the hydraulic fluid. It
allows for fluid volume changes associated with fluid expansion and cylinder differential volumes.
Minimum reservoir capacity depends on the volume needed to perform these functions. Typically, a
capacity of one to three times the pump flow (per minute) is satisfactory.
Locate the reservoir outlet (suction line) near the bottom, allowing clearance for settling foreign particles.
Place the reservoir inlet (return lines) below the lowest expected fluid level, as far away from the outlet as
possible.

Control Type
NPNN (Pressure Compensated Control)
D1P 130/145/193/260+NPNN
Pressure Compensated Control (P) Principle
The P control design maintains a constant pressure in the hydraulic circuit as flow varies. The P control
modulates pump flow accordingly to maintain system pressure at the P setting as the P adjusting screw
and spring defines.
Pressure Compensated Control (P) Operation
When system pressure, acting on the non-spring end of the P spool, overcomes the force of the P spring,
the spool shifts porting system pressure to the servo piston and the swashplate angle decreases. When
system pressure drops below the P setting, the P spring shifts the spool in the opposite direction
connecting the servo piston to pump case and the swashplate angle increases. The swashplate is
maintained at whatever angle is required to keep system pressure at the P setting.
P characteristic
Warning
A relief valve is required to be installed in the pump outlet for additional system protection. Failure to
install the relief valve can lead to system damage and/or injury.

NPSN (Pressure Compensated Control + Load Sensing Control)
D1P 130/145/193/260+NPSN
Pressure Compensated Control (P) Principle and Operation
Please refer to NPNN (Pressure Compensated Control) on page 32
Load Sensing Control (S) Principle
The S control design matches pump flow with system demand. The S control senses the flow demand of
the system as a pressure drop across the external control valve (1).
As (1) opens and closes, the pressure difference (delta) across the valve changes. When opening, the delta
decreases. When closing, the delta increases. The S control then increases or decreases pump flow to the
system until the pressure delta becomes equal to the S setting as defined by the S adjusting screw and
spring.
Load Sensing Control (S) Operation
Through internal porting, system pressure [upstream of (1)] is applied to the non-spring end of the S
spool, and through hydraulic line connected at port X, load pressure [downstream of (1)] is applied to the
spring end. This arrangement allows the S spool to act on the delta between system pressure and load
pressure. The S spring sets the threshold of operation (S setting).
Because the swashplate is biased to maximum angle, the pump attempts to deliver full flow to the
hydraulic system. When the flow being delivered exceeds demand, the pressure delta across the (1) is
great enough to overcome spring force and shift the S spool porting system pressure to the servo piston.
The pump de-strokes reducing flow until the delta across the (1) becomes equal to the S setting.
When flow being delivered is less than demand, the delta across the (1) drops below the S setting and the
S spring shifts the spool connecting the servo piston to pump case. The pump strokes increasing flow
until the delta across the (1) becomes equal to the S setting.
When the external control valve (1) is placed in neutral, it connects the LS signal line to drain. With no LS
pressure acting on the non-spring end of the LS spool, the pump adjusts stroke to whatever position
necessary to maintain system pressure at the LS setting. The pump is now in low pressure standby mode.

Pressure Compensated Control (P) Principle and Operation
Please refer to NPNN (Pressure Compensated Control) on page 32.
Remote Pressure Compensated Control (R) Principle
The remote PC control is a two-stage control that allows multiple PC settings. Remote PC controls are
commonly used in applications requiring low and high pressure PC operation.
For this control, Danfoss recommends a load sense setting of 25 bar.
Remote Pressure Compensated Control (R) Operation
The remote PC control uses a pilot line connected to an external hydraulic valve. The external valve
changes pressure in the pilot line, causing the PC control to operate at a lower pressure. When the pilot
line is vented to reservoir, the pump maintains pressure at the load sense setting. When pilot flow is
blocked, the pump maintains pressure at the PC setting. An on-off solenoid valve can be used in the pilot
line to create a low-pressure standby mode. A proportional solenoid valve, coupled with a
microprocessor control, can produce an infinite range of operating pressures between the low pressure
standby setting and the PC setting.

Warning
A relief valve is required to be installed in the pump outlet for additional system protection. Failure to
install the relief valve can lead to system damage and/or injury.
NPNR Priority
When the pump’s X-port is vented to tank, or limited to some pressure setting via a remote valve, the
remote pressure compensator function will control the maximum outlet pressure of the pump. If the
pump’s outlet pressure reaches the pressure setting of the pressure compensator (PC) function, the PC
function will take priority and limit the pump’s maximum pressure.

Power Control (T) Principle
The power control regulates the displacement of the pump depending on the working pressure so that a
given drive power is not exceeded at constant drive speed, this function can prevent engine stall or
protect electric generator.
PB = working pressure
PB • Vg = CVg = displacement
C = constant
The precise control with a hyperbolic control characteristic, provides an optimum utilization of available
power.
Power Control (T) Operation
The working pressure acts on a rack-pivot via a roller jack which produces a rotating torque, an externally
adjustable spring force counteracts this which determines the power setting.
If the moment generated by working pressure exceeds the moment generated by spring force, the
control valve is actuated by the rack-pivot, and pump reduces displacement. The lever length at the rackpivot is shortened and the working pressure can increase at the same rate as the displacement decreases
without the drive powers being exceeded.
(PB • Vg = C).
The hydraulic output power (characteristic T) is influenced by the efficiency of the pump.

D1P 130/145/193/260 NNES
Electric Displacement Control (E) Principle
The electric displacement control uses an electric proportional solenoid valve to vary the pump’s
displacement from minimum displacement to maximum displacement or from maximum displacement
to minimum displacement. The swashplate angle (pump displacement) is proportional to the electrical
input signal (control current).
Electric Displacement Control (E) Operation
This control is current driven, requiring a Pulse Width Modulated (PWM) signal. Pulse width modulation
allows more precise control of current to the solenoid. The PWM signal causes the solenoid pin to push
against the E spool, which depressurizes the end of servo piston, the swashplate angle increases under
the force of the bias piston
A swashplate feedback link provides swashplate position force to the solenoid through the E spool’s
linear spring. The control reaches equilibrium when the position of the swashplate spring feedback force
exactly balances the input command solenoid force from the operator. As working pressure changes with
load, the control and servo/swashplate system work constantly to maintain the commanded position of
the swashplate.
Electric Displacement Control (E) Operating Instruction
To make sure the electric displacement control works properly, a minimum control pressure of 30 bar
[435 psi] is required. The required control pressure is taken either from the working pressure, or from the
externally applied control pressure at the E port.
If you can’t make sure that the working pressure is above 30 bar all the time, then a minimum of 30bar
[435 psi] pressure supply at the E port is mandatory in order to control the displacement of the pump at
all times. This pressure supply can be provided from different sources, such as an additional small gear or
piston pump and a relief valve, or an accumulator.
If E port is not connected, remove the shuttle valve
Each Electric Displacement Control (EDC) is equipped with a Manual Over Ride (MOR) function for
temporary actuation of the control to aid in diagnostics, even if insufficient or no current is supplied to
the solenoid actuator. Initial activation of the MOR function will require a higher force to overcome the
sticking effect between the pin and O-ring seal. Repeated activation of this functionality should provide
better controllability.

Fill pump case with clean oil before start
Suction (absolute) : P min = 0.6 bar with charge pump (0.8 bar without charge pump), P max = 2 bar. Do
not restrict suction line
Drain (absolute) : P max = 2 bar. Do not restrict drain line, do not combine drain line

Caution! Installation hazards!
Failure to adhere to the installation notes may result in shortened product life.
The maximum allowable suction height is 0.8m. The allowable suction height is derived from the total
pressure loss.
The D1 pump with charge pump is not designed for above-Reservoir installation.
For control options with pressure controllers, proportional displacement control, the minimum
displacement setting must be Vg ≥ 5% Vg max.
Recommendation for arrangement 7 (shaft upwards): A check valve in the case drain line (cracking
pressure 0.5 bar) can prevent draining of the case interior.

It is recommended to fit a pipe to the suction port S and fitting a pipe to case drain port L1, L2 or L3
and S ports through position below
the hydraulic fluid level.
(See arrangements), the other case drain ports must be plugged in this situation. The pump should be
filled before fitting the pipe and filling the tank with hydraulic fluid.
•
It is only permissible to install a pump with solenoids (E.g. a pump with electric displacement control)
at tank-level, if used hydraulic fluids are based on mineral oil and the oil temperature in the tank does
not exceed 80° C.
