System Requirements
Pressure
The inlet vacuum must be controlled in order to realize expected pump life and performance. The system
design must meet inlet pressure requirements during all modes of operation. Expect lower inlet
pressures during cold start. It should improve quickly as the fluid warms.

Max. intermittent vacuum

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 accompanying illustration
shows peak pressure in relation to rated pressure and reaction time (100 ms maximum).
Rated pressure is the average, regularly occurring, operating 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.
System pressure is the differential of pressure between the outlet and inlet ports. It is a dominant
operating variable affecting hydraulic unit life. High system pressure, resulting from high load, reduces
expected life. System pressure must remain at, or below, rated pressure during normal operation to
achieve expected life.
Speed
Maximum speed is the limit recommended by Danfoss for a particular gear pump when operating 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. It is the lowest speed at which normal life can
be expected. The minimum speed increases as operating pressure increases. When operating under
higher pressures, a higher minimum speed must be maintained, as illustrated here.

Hydraulic fluids
Temperature and viscosity
Ratings and data for TAP4NN gear pumps are based on operating 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. They include:
•
•
•
•
Use only clean fluid in the pump and hydraulic circuit.
Never mix hydraulic fluids.
Temperature and viscosity requirements must be concurrently satisfied. Use petroleum / mineralbased fluids.
High temperature limits apply at the inlet port to the pump. The pump should run at or below the
maximum continuous temperature. The peak temperature is based on material properties. Don’t exceed
it.
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 [60 °F] above the pour point of
the hydraulic fluid.
Minimum (cold start) temperature relates to the physical properties of component materials.
Minimum viscosity occurs only during brief occasions of maximum ambient temperature and severe duty
cycle operation. You will encounter maximum viscosity only at cold start. During this condition, limit
speeds until the system warms up. Size heat exchangers to keep the fluid within these limits. Test
regularly to verify that these temperatures and viscosity limits aren’t exceeded. For maximum unit
efficiency and bearing life, keep the fluid viscosity in the recommended viscosity range.

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 β
•
return or pressure filtration, use a pressure filtration with an efficiency of β10 = 75
35-45
= 75 filter
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.

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.

Technical Information
Gear Pumps Group 4 Technical Information
System Requirements
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
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 pipe sizes that accommodate minimum fluid velocity to reduce system noise, pressure drops, and
overheating. This maximizes system life and performance.
Design inlet piping that maintains continuous pump inlet pressure above 0.8 bar absolute during normal
operation. The line velocity should not exceed the values in this table:
Maximum line velocity
Inlet
Outlet
Return
m/s [ft/sec]
2.5 [8.2]
5.0 [16.4]
3.0 [9.8]
Pump drive
Most systems use hydraulic oil containing 10% dissolved air by volume. Under high inlet vacuum
conditions the oil releases bubbles. They collapse when subjected to pressure, resulting in cavitation,
causing adjacent metal surfaces to erode. Over-aeration is the result of air leaks on the inlet side of the
pump, and flow-line restrictions. These include inadequate pipe sizes, sharp bends, or elbow fittings,
causing a reduction of flow line cross sectional area. This problem will not occur if inlet vacuum and rated
speed requirements are maintained, and reservoir size and location are adequate.
Shaft options for Group 4 gear pumps include tapered, splined, or parallel shafts. They are suitable for a
wide range of direct and indirect drive applications for radial and thrust loads.
Plug-in drives, acceptable only with a splined shaft, can impose severe radial loads when the mating
spline is rigidly supported. Increasing spline clearance does not alleviate this condition.
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.

System Requirements
Caution
In order to avoid spline shaft damages it is recommended to use carburized and hardened steel
couplings with 80-82 HRA surface hardness.
Allowable radial shaft loads are a function of the load position, load orientation, and operating pressure
of the hydraulic pump. All external shaft loads have an effect on bearing life, and may affect pump
performance.
In applications where external shaft loads can’t be avoided, minimize the impact on the pump by
optimizing the orientation and magnitude of the load. Use a tapered input shaft; don’t use splined shafts
for belt or gear drive applications. A spring-loaded belt tension-device is recommended for belt drive
applications to avoid excessive tension. Avoid thrust loads in either direction.
Pump drive data form
Contact Danfoss if continuously applied external radial or thrust loads occur. Fill out this page and send
the complete form to your Danfoss representative for an assistance in applying pumps with belt or gear

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 that have an oil film maintained between the
gear/shaft and bearing surfaces at all times. If the oil film is sufficiently sustained through proper system
maintenance and operating within recommended limits, long life can be expected.
B10 life expectancy number is generally associated with rolling element bearings. It does not exist for
hydrodynamic bearings.
High pressure, resulting from high loads, impacts pump life. When submitting an application for review,
provide machine duty cycle data that includes percentages 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.

Danfoss recommends mating splines conform to SAE J498 or DIN 5482. Danfoss external SAE splines have
a flat root side fit with circular tooth thickness reduced by 0.127 mm [0.005 in] in respect to class 1 fit.
Dimensions are modified to assure a clearance fit with the mating spline.
Caution
Shaft torque capability may limit allowable pressure. Torque ratings assume no external radial loading.
Applied torque must not exceed these limits, regardless of stated pressure parameters. Maximum torque
ratings are based on shaft torsional fatigue strength.
Various port configurations are available on Group 4 pumps. They include:
•
SAE split flange ports
•
European standard flanged ports
