D Series and XD Series Gear Pumps

General Information

Overview

Features and benefits

Quick chart 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.

•High strength cast iron construction allows consistently efficient performance and long life in continuous 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 internal lubircation 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 the need for most bolt-on outrigger bearings.

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 iron provides contamination resistance, thermal stability and the strength needed for consistently high levels of 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

General Information

design pump. In addition, the proximity of the front bearing to the mounting flange increases the radial load 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 high strength 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 can be accommodated with sealed auxiliary covers between sections.

Pressure

Use these formulas to determine the nominal pump size for a specific application.

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).

Technical Information

D Series and XD Series Gear Pumps

Operating Parameters

System pressure

System pressure is the differential between the inlet and outlet ports. It is a dominant operating variable affecting hydraulic unit life. High system pressure reduces expected pump life. System pressure must remain 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 during cold 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 port of 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, the system 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 to flow 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 can be 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 than minimum 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. (Duty

cycle 1% or less)

Maximum viscosity occurs only during cold start at very low temperatures. It is the upper limit of viscosity 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 at which normal life can be expected.

The lower limit of operating speed is the minimum speed.

D Series and XD Series Gear Pumps

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 to prevent 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 the system)

•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 better
βx 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 and prevent large foreign particles from entering the line. Cover the line with a 100-125 micron screen. The

Operating Parameters

pump should be below the lowest expected fluid level. Put the return-line below the lowest expected fluid level to allow discharge into the reservoir for maximum dwell and efficient deaeration. A baffle (or baffles) 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, and overheating 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 all pressure ratings.

	Inlet	m/sec [ft/sec]	2.4-4.3 [8-14]
	Outlet		6-9 [20-30]

Most systems use hydraulic oil containing 10% dissolved air by volume. Over-areation, or entrained air is the result of flow line restrictions, where the dissolved air comes out of solution, or when air is allowed to leak 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 circuit recommendations are followed, rated speed requirements are maintained, and reservoir size and location are adequate.

Pump life

Pump life is a function of speed, system pressure, and other system parameters (such as fluid quality and cleanliness).

All Danfoss gear pumps use hydrodynamic journal bearings with an oil film between the gear/shaft and bearing surfaces. If the oil film is sufficiently sustained through proper system maintenance and operating within recommended limits, long life can be expected.

ß10 life expectancy number is generally associated with rolling element bearings. It does not exist for hydrodynamic bearings.

When submitting an application for review, provide machine duty cycle data including percentage of time 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 with radial shaft loads. The table below shows the preferred orientation for radial loads assuming maximum pressure. For assistance concerning shaft loading, contact your Danfoss representative.
