Technical Information
Rugid Cast Iron Group 2.5 Pump
General Information
Overview
The D Series fixed displacement gear pump has been specifically designed for demanding mobile
equipment applications where maximum performance is required at peak power levels and operating
temperatures.
The design integrates cast iron construction with pressure balanced thrust plates to deliver consistent
efficiency across the entire operating range of pressure, speed, and temperature; all in an industryleading package size that maximizes power density.
Features and benefits

•
•
•
•

High strength cast iron construction allows consistently efficient performance and long life incontinuous operation at 276 bar [4000 psi] and peak conditions of 303 bar [4400 psi].
Custom engineered bearings, pressure-balanced load plates, and viton seals optimize internallubircation allowing for long life with intermittent fluid temperatures up to 115 °C [239 °F] and fluid
viscosities as low as 8 mm2/sec (cSt) [36 SUS].
Compact three-piece design maximizes power density and creates one of the shortest multisection
pumps (with up to four pumping sections) in the global marketplace.
Bearings located in the front flange increase radial/axial load carrying capability and eliminate theneed for most bolt-on outrigger bearings.

Quick chart overview
The D Series pump blends the traditional Group 2 (SAE-A) and Group 3 (SAE-B) frame sizes in a single
package with displacements from 7 to 45 cm3 (0.43 to 2.75 in3).
These displacements, in addition to a wide variety of shafts, flanges, ports, and integrated valve options
can be used in virtually any combination to offer greater design flexibility and meet specific application
requirements.

Cast iron housings, bearings
The three piece structural members of the pump are made of high-strength cast ductile iron. Cast ironprovides contamination resistance, thermal stability and the strength needed for consistently high levelsof performance and durability needed in demanding off highway applications.
Heavy-duty low friction PTFE-lined sleeve bushings are optimized to provide long life in low viscosity,
high pressure conditions. The bearings are located in the front mounting flange, rear cover, and bearing
plate (for multiple section pumps) and allow the D pump to be 20% shorter than a typical bearing block© Danfoss | February 2023

General Information
design pump. In addition, the proximity of the front bearing to the mounting flange increases the radialload capacity of the pump, eliminating the need for most bolt-on outrigger requirements.
Pressure balance, sealing
The pump incorporates two steel-backed bronze thrust plates seated in depressions in the mounting
flange, rear cover, and bearing plate (for multiple section pumps). Underneath the front plate (known as
the deflecting plate) is the load seal.
The E-shaped load seal distributes system pressure underneath the plate and enables the plate to deflect
and maintain a tight sealing surface against the side face of the gears.
The tight sealing action allows the pump to maintain very high levels of volumetric efficiency, even when
operating in extreme temperature, pressure and speed conditions.
One-piece gear design
All D Series pump gear shafts are of one-piece design. This enables the shaft to provide uniform highstrength and accurate gear profile relative to the journals for smooth mesh operation. The integral gear
shafts are made of heat treated AISI 8620 steel, manufactured to precise tolerances and surface finishes,for maximal life and minimal leakage. This integral design eliminates the potential problems of fatigue
stress and gear face mismatch often associated with two-piece gear shaft designs.
Multiple pump configuration
D Series pumps can be coupled together to produce tandem, triple and even quadruple section units.
The interconnecting chambers accommodate fluid flow between sections and allow the number of inlet
connections to be minimized. Systems that require operation with different fluids and/or reservoirs canbe accommodated with sealed auxiliary covers between sections.

Operating Parameters
Sizing equations
Use these formulas to determine the nominal pump size for a specific application.

Pressure
Definitions of the D Series operating parameters appear below. Consult Danfoss technical support for
applications running outside of these parameters.
Peak pressure
Peak pressure is the highest intermittent pressure allowed. The relief valve overshoot (reaction time)
determines peak pressure. It is assumed to occur for less than 100 ms. The illustration to the right shows
peak pressure in relation to rated pressure and reaction time (100 ms maximum).

Rated pressure
Rated pressure is the average, regularly occurring operating outlet pressure that should yield satisfactory
product life. The maximum machine load demand determines rated pressure. For all systems, the load
should move below this pressure.

Technical Information
Rugid Cast Iron Group 2.5 Pump
Operating Parameters
System pressure
System pressure is the differential between the inlet and outlet ports. It is a dominant operating variableaffecting hydraulic unit life. High system pressure reduces expected pump life. System pressure mustremain at, or below, rated pressure during normal operation to achieve expected life.
Inlet vacuum
Inlet vacuum must be controlled in order to realize expected performance and pump life. System design
must meet inlet vacuum requirements during all modes of operation. Expect lower inlet vacuums duringcold start situations. Low vacuum condition should improve quickly as fluid warms.
Pressure rise rate
The maximum pressure rise rate is the rate of increase in system pressure as measured at the outlet portof the pump. High pressure rise rates are commonly seen on work function applications during motor
start-up, completion of cylinder stroke, and during rapid shifting of control valves. The maximum
pressure rise rate of the D pump is 11,720 bar/sec [170,000 psi/sec]. During rapid rise rate situations, thesystem pressure must not exceed the rated pressure of the pump.
Temperature and viscosity
Temperature
High temperature limits apply at the inlet port of the pump. The pump should run at or below the
maximum continuous temperature.
Minimum (cold start) temperature relates to the physical properties of component materials.
Cold oil, generally, doesn’t affect the durability of pump components. It may affect the ability of oil toflow and transmit power. For this reason, keep the temperature at 16°C [29 °F] above the pour point of
the hydraulic fluid.
Continuous temperature is the temperature at or below the temperature which normal pump life canbe expected.
Maximum temperature is the highest temperature that is tolerable by the machine for a transient/
limited time (duty cycle 1% or less). At maximum temperature, oil viscosity must not go lower thanminimum recommended viscosity.
Viscosity
Continuous viscosity: Recommended viscosity range for maximum efficiency and pump life.
Minimum viscosity occurs only during brief occasions of maximum fluid temperature and severe duty
cycle operation. It’s the minimum acceptable viscosity to guarantee the pump life. (Dutycycle 1% or less)Maximum viscosity occurs only during cold start at very low temperatures. It is the upper limit ofviscosity that allows the pump to start. During this condition, limit speeds until the system warms up.
Temperature and viscosity requirements must be concurrently satisfied.
Speed
Maximum speed is the limit recommended for operation at rated pressure. It is the highest speed atwhich normal life can be expected.
The lower limit of operating speed is the minimum speed.

Technical Information
Rugid Cast Iron Group 2.5 Pump
Operating Parameters
Hydraulic fluid
Ratings and data for gear pumps are based on operation with premium hydraulic fluids containing
oxidation, rust, and foam inhibitors. These fluids must possess good thermal and hydrolytic stability toprevent wear, erosion, and corrosion of internal components.
Use only clean fluid in the pump and hydraulic circuit.

C Caution
Never mix hydraulic fluids.
Filtration
Filters
Use a filter that conforms to Class 22/18/13 of ISO 4406 (or better). It may be on the pump outlet(pressure filtration), inlet (suction filtration), or reservoir return (return-line filtration).
Selecting a filter
When selecting a filter, please consider:contaminant ingression rate (determined by factors such as the number of actuators used in thesystem)• generation of contaminants in the system• required fluid cleanliness• desired maintenance interval• filtration requirements of other system components•

Measure filter efficiency with a Beta ratio (βX). For:suction filtration, with controlled reservoir ingression, use a β35-45 = 75 filter
return or pressure filtration, use a pressure filtration with an efficiency of β10 = 75••

βx ratio is a measure of filter efficiency defined by ISO 4572. It is the ratio of the number of particles
greater than a given diameter ( “X“ in microns) upstream of the filter to the number of these particles
downstream of the filter.
Fluid cleanliness level and βx ratio
Fluid cleanliness level (per ISO 4406)

Class 22/18/13 or betterβx ratio (suction filtration)

β35-45 = 75 and β10 = 2

βx ratio (pressure or return filtration)β10 = 75

Recommended inlet screen size

100-125 µm [0.004-0.005 in]

The filtration requirements for each system are unique. Evaluate filtration system capacity by monitoring
and testing prototypes.
Reservoir
The reservoir provides clean fluid, dissipates heat, removes entrained air, and allows fluid volume
changes associated with fluid expansion and cylinder differential volumes. A correctly sized reservoir
accommodates maximum volume changes during all system operating modes. It promotes deaeration of
the fluid as it passes through, and accommodates a fluid dwell-time between 60 and 180 seconds,
allowing entrained air to escape.
Minimum reservoir capacity depends on the volume required to cool and hold the oil from all retracted
cylinders, allowing for expansion due to temperature changes. A fluid volume of 1 to 3 times the pump
output flow (per minute) is satisfactory. The minimum reservoir capacity is 125% of the fluid volume.
Install the suction line above the bottom of the reservoir to take advantage of gravity separation andprevent large foreign particles from entering the line. Cover the line with a 100-125 micron screen. The© Danfoss | February 2023

Technical Information
Rugid Cast Iron Group 2.5 Pump
Operating Parameters
pump should be below the lowest expected fluid level. Put the return-line below the lowest expectedfluid level to allow discharge into the reservoir for maximum dwell and efficient deaeration. A baffle (orbaffles) between the return and suction lines promotes deaeration and reduces fluid surges.
Line sizing
Choose line sizes that accommodate maximum fluid velocity to reduce system noise, pressure drops, andoverheating in order to maximize system life and performance. Line velocities shown in the following
table provide a general rule of thumb. Final selection of line sizing and fittings must comply with allpressure ratings.

Most systems use hydraulic oil containing 10% dissolved air by volume. Over-areation, or entrained air isthe result of flow line restrictions, where the dissolved air comes out of solution, or when air is allowed toleak into the hydraulic circuit. These include inadequate pipe sizes, sharp bends, or elbow fittings,
causing reduction of flow-line cross-sectional area. This problem will not occur if these circuitrecommendations are followed, rated speed requirements are maintained, and reservoir size andlocation are adequate.
Pump life
Pump life is a function of speed, system pressure, and other system parameters (such as fluid quality andcleanliness).
All Danfoss gear pumps use hydrodynamic journal bearings with an oil film between the gear/shaft andbearing surfaces. If the oil film is sufficiently sustained through proper system maintenance andoperating within recommended limits, long life can be expected.
ß10 life expectancy number is generally associated with rolling element bearings. It does not exist forhydrodynamic bearings.
When submitting an application for review, provide machine duty cycle data including percentage oftime at various loads and speeds. We strongly recommend a prototype testing program to verify
operating parameters and their impact on life expectancy before finalizing any system design.
Pump shaft connection
Shaft options for gear pumps include tapered, splined, or parallel shafts.
Plug-in drives, with a splined shaft, can impose severe radial loads when the mating spline is rigidly
supported. Increasing spline clearance does not alleviate this condition.

Operating Parameters
Lubricate all shaft couplings. Failure to do so will result in premature shaft failure.
Use plug-in drives if the concentricity between the mating spline and pilot diameter is within 0.1 mm[0.004 in]. Lubricate the drive by flooding it with oil. A 3-piece coupling minimizes radial or thrust shaft
loads.

C Caution
To avoid spline shaft damages it is recommended to use carburized and hardened steel couplings with
80-82 HRA surface hardness.
Radial and axial loading
Allowable radial shaft loads are a function of the load position, load orientation, and operating pressure.
All external shaft loads have an effect on bearing life, and may affect pump performance.
In applications where external shaft loads cannot be avoided, minimize the impact on the pump by
optimizing the orientation and magnitude of the load. Use tapered input shafts for applications withradial shaft loads. The table below shows the preferred orientation for radial loads assuming maximum
pressure. For assistance concerning shaft loading, contact your Danfoss representative.

multiple pump does not have isolated sections. Applications requiring sealing between sections should
use the SAE auxiliary flange to ensure separation of fluids between sections.
The reference drawings and model code options (R, L, and N) below, describe the first and intermediate
port sections of multiple pump configurations. Refer to module D for port options on the final section ofa multiple pump.

The auxiliary flange option does not ship with a running cover. If the pump will be operated without an
auxiliary pump, install a running cover to prevent environmental contamination.
Integrated Priority Flow Divider

Integrated Priority Flow Divider
D series pumps are available with an optional Priority Flow Divider (PFD) valve integrated into the rearcover. The PFD divides the flow and provides a fixed amount of Controlled Flow (CF) to priority functions
such as steering. The remaining flow is routed to the Excess Flow (EF) port for additional functions such as
directional control valves and fan drives. The priority flow is pressure compensated and is therefore
independent of the excess flow working pressures. The priority flow circuit has an integral, direct acting
pilot relief valve with internal drain.
Relief valves are available to suit application pressure and flow requirements. Cartridge style relief pressures to 221 bar (3200 psi), flows to 34.3 l/min (9 US gal/m)
The D series PFD can be used in tandems and other multiple pump configurations, but only in the rearpumping section. A variety of port sizes and port locations are available. Pumps with PFD covers arerotation specific and require a unique front mounting flange to accommodate the spacing of theassembly bolts.

Load Sense Priority Flow ValveD series pumps are available with an optional Load Sense (LS) priority valve integrated into the rearcover.
The LS priority valve supplies priority flow on demand to functions such as load sense steering, while theExcess Flow (EF) is available for secondary functions such as directional control valves and fan drives.
A load sense signal line from the priority circuit to the gear pump’s LS port governs flow to the primarycircuit. As the load sense signal pressure increases, priority (CF) flow also increases. When the controlled
function is idle (no load sense demand), full pump flow is available for the secondary functions.
• The D series LS priority valve is available with 40 l/min [10 US gal/min] and 80 l/min [21 US gal/min]flow settings.
• The priority circuit is available with an optional integral direct acting pilot relief valve with internal
drain. Pressure settings range from 34 to 172 bar [500 to 2500 psi].
• The load sense valve is dynamic and has a constant flow of 0.5 to 1.0 l/min [0.13 to 0.26 US gal/min]present at all times to ensure fast reaction.
• The D series PFD can be used in tandems and other multiple pump configurations, but only in therear pumping section.
• Rear and side porting options are available.

How to determine overall length
The overall length of the single section pump (as measured from the mounting flange) can be calculated
by adding the dimension of the mounting flange to the combined length of the pumping section. The
length of the pumping section is dependent upon the displacement (dimension Z) and the selection ofports (standard or oversized).
Overall length of single section pump = 35.3 [1.39] + 1Z + 1A
How to determine the position of inlet/outlet ports
Generally speaking, the inlet and outlet ports are centrally located within each port section. Therefore,
the position of the inlet/outlet port (as measured from the mounting flange) can be calculated as follows:
Location of port 1 = 35.3 [1.39] + 1Z + 1B
