SPOOL VALVE - The distributor valve has been integrated with the output shaft. The valve has hydrodynamic bearings, and hasinfinite life when load ratings are not exceeded.
GEAR SET - There are two forms of stator, hence and of gear set:
EPMM, EPM and EPML have plain teeth. These types motors are suitable for long operating periods at moderate pressures- orshort operating periods at high pressures.
EPRM, EPRML and EPMH have teeth fitted with rollers. The rollers reduce local stress and the tangential reaction forces on therotor reducing friction to a minimum. This gives long operating life and better efficiency even at continuous high pressures. RollerGear Sets are recommended for operation with thin oil and for applications having continually reversing loads.
The standard motor mounting flange is located as close to the output shaft as possible. This type ofmounting supports the motor close to the shaft load. This mounting flange is also compatible with manystandard gear boxes.
Standard Motor
This type mounting flange makes the motor possible to fit a wheel hub or a winch drum so that the radialload acts midway between the two motor bearings. This gives the best utilization of the bearing capacityand is a very compact solution.
Wheel Motor
EPM and EPRM have an output shaft supported in needle bearing. These types motors are suitable forabsorbing static and dynamic radial loads.
Needle Bearing
The operating principle of the motors is based on an internal gear design, consisting of a stator and rotor through which theoutput torque and speed are transmitted. The distributor valve is driven synchronously by the rotor through a cardan shaftensuring that each one of the chambers of the motor are filled and emptied precisely.
EPMM, EPM, EPML, EPRM, EPRML and EPMH motors have a Spool Valve.
LSV Series hydraulic motors have been designed to operate with normal pressure drop and to ensuresmooth run at low speed (up to 200 min ), as the best security for operation is guaranteed at frequencyof rotation 20 ÷ 50 min . They have an increased starting pressure drop and are not recommended forusing at pressure less than 40 bar.

LL Series hydraulic motors have been designed to operate at the whole standard range of workingconditions (pressure drop and frequency of rotation ) , but with considerable decreased volumetric lossesin the drainage ports. Their main purpose is to operate as series-connected motors in hydraulic systems.For this version is permissible decreasing of the maximal torque with up to 5% (at middle speed) and upto 10 % (at high speed) in comparison to the standard versions of motors.

Look at specification data for hydraulic motors series EPM standard version. Only the parameter Starting Pressure ismodified.
version “FR” these are the hydraulic motors with reduced mechanical losses , for wich at disengagedcondition / unconnected with driving mechanism / the rotation of the shaft could be realized by means of small torque.This advantage is especially usefull at operating with high frequencies of rotation /over than 300 min / and low pressuredrop , which is inbred for types with displacements of up to 200 cm . It is normal for these for the different condition ofoperation to have high torque , as well as high volume losses : the values of the volumetric efficiency are lower ( up to 5 %for middle and up to 10 % for high values of the pressure drop ) , than these of the normal versions. That's why therecommended operating for “FR version is for applications with pressure drop up to 100 bar.
Additional advantages of “FR” version are prolonging of the life of the hydraulic motors at high frequencies ofrotation, as well as the possibility to use them in systems with big variation of the loading.

Low Speed Valve (LSV) “LSV” Series hydraulic motors have been designed to operate with normal pressure drop and toensure smooth run at low speed (up to 200 RPM), as the best security for operation is guaranteed at frequency of rotation20 ÷ 50 RPM . They have an increased starting pressure drop and are not recommended for using at pressure less than40 bar.Look at specification data for hydraulic motors standard version. The modification concerns only the followingparameters: maximum speed , maximum output, maximum Oil flow and maximum starting pressure.

Look at specification data for hydraulic motors series EPM standard version. The modification concerns only theparameters: maximum torque, maximum output, minimum starting torque.
“LL” Series hydraulic motors have been designed to operate at the whole standard range ofworking conditions (pressure drop and frequency of rotation ) , but with considerable decreased volumetric losses in thedrainage ports. Their main purpose is to operate as series-connected motors in hydraulic systems.
For this version is permissible decreasing of the maximal torque with up to 5% (at middle speed) and up to 10%(at high speed) in comparison to the standard versions of motors.

Look at specification data for hydraulic motors series EPRM standard version. Only the parameter Starting Pressure ismodified.
version “FR” these are the hydraulic motors with reduced mechanical losses , for wich at disengagedcondition / unconnected with driving mechanism / the rotation of the shaft could be realized by means of small torque.This advantage is especially useful at operating with high frequencies of rotation /over than 300 min / and low pressuredrop , which is inbred for types with displacements of up to 200 cm . It is normal for these for the different condition ofoperation to have high torque , as well as high volume losses: the values of the volumetric efficiency are lower ( up to 5 %for middle and up to 10% for high values of the pressure drop ) , than these of the normal versions. That's why therecommended operating for “FR version is for applications with pressure drop up to 100 bar.
Additional advantages of “FR” version are prolonging of the life of the hydraulic motors at high frequencies ofrotation, as well as the possibility to use them in systems with big variation of the loading.

EPMS, EPMT and EPMV are suitable for continuous operation under rough operating conditions- high pressures, thin oil, orfrequent reversals. The Tapered roller bearings permit high radial loads.
DISC VALVE 's function is to distribute fluid to the Roller Gear Set. The pressure balanced sealing surface on the valve faceand the separately driven maintains minimal leakage and mechanical losses. These gives the motors high efficiency- even athigh pressures, and good starting characteristics.
ROLLER GEAR SET minimizes friction and thereby increases efficiency while providing smooth output shaft rotation.
DISC VALVE HYDRAULIC MOTORS
The standard motor mounting flange is located as close to the output shaft as possible. This type ofmounting supports the motor close to the shaft load. This mounting flange is also compatible with manystandard gear boxes.
Standard Motor
The wheel motor mounting flange is located near the center of the motor which permits part or all of themotor to be located inside the wheel or roller hub. In traction drive applications, loads can be positionedover the motor bearings for best bearing life. This wheele motor mounting flange provides designflexibility in many applications.
Wheel Motor
59
This motor is assembled without the output shaft, bearings and bearing housing and has the same drivecomponents as the standard and wheel motors. The short motor is especially suited for applications suchas gear boxes, winch, reel and roll drives. Short motor applications must be designed with a bearingsupported internal spline to mate with the bearing less motor drive. Product designs using thesehydraulic motors provide considerable cost savings.

Releasing the level, the springs pull it and the brake pads backto the initial position. The motor output shaft is released.Minimum angle adjustment is 10 . It can be adjusted bydismounting the level. Depending on the application You canchoose the actuating direction of the brake level. The rodconnection actuating the brake should be capable of moving atlast 25 mm from neutral to extreme position.

Actuating the brake level, the brake shaftis turned. The rectangular shape of theinner part of this shaft forces the brakepads to be pressed against the brakedrum. This brakes the wheel or the winchdrum.
The output shaft runs in tapered bearings that permithigh axial and radial forces.Curve "1" shows max. radial shaft load. Any shaft loadexceeding the values quoted in the curve will seriouslyreduce motor life. The two other curves apply to a B10bearing life of 3000 hours at 200 RPM.

Low Speed Valve (LSV) “LSV” Series hydraulic motors have been designed to operate with normal pressure dropand to ensure smooth run at low speed (up to 200 min ), as the best security for operation is guaranteed atfrequency of rotation 20 ÷ 50 min . They have an increased starting pressure drop and are not recommended forusing at pressure less than 40 bars.

Look at specification data for hydraulic motors standard version. The modification concerns only the followingparameters : maximum speed , maximum output, maximum Oil flow and maximum starting pressure.
Look at specification data for hydraulic motors standard version. The modification concerns only theparameters: maximum torque, maximum output, minimum starting torque.
“LL” Series hydraulic motors have been designed to operate at the whole standard range ofworking conditions (pressure drop and frequency of rotation ) , but with considerable decreased volumetric losses inthe drainage ports. Their main purpose is to operate as series-connected motors in hydraulic systems.
For this version is permissible decreasing of the maximal torque with up to 5% (at middle speed) and up to10% (at high speed) in comparison to the standard versions of motors.

* Intermittent operation: the permissible values may occur for max. 10% of every minute.** Peak load: the permissible values may occur for max. 1% of every minute.*** For speeds of 5 RPM lower than given, consult factory or your regional manager.
1) Intermittent speed and intermittent pressure must not occur simultaneously.
2) Recommended filtration is per ISO cleanliness code 20/16. A nominal filtration of 25 micron or better.
3) Recommend using a premium quality, anti-wear type mineral based hydraulic oil, HLP(DIN51524) or HM(ISO6743/4).
4) Recommended minimum oil viscosity 13 mm²/s at 50ºC.
5) Recommended maximum system operating temperature is 82ºC.
6) To assure optimum motor life fill with fluid prior to loading and run at moderate load and speed for 10-15 minutes.
If using synthetic fluids consult the factory for alternative seal materials.

DRAIN CONNECTION
A drain line ought to be used when pressure in the return line can exceed the permissible pressure. It can be
connected:
- For EPMTS at the drain port of the motor;
- For EPMTV at the drain connection of the attached component.
The drain line must be possible for oil to flow freely between motor and attached component and must be led to the
tank. The maximum pressure in the drain line is limited by the attached component and its seal.
The maximum pressure in the drain line is limited
by the attached component and its shaft seal.
PERMISSIBLE SHAFT LOADS
The output shaf t runs in tapered bear ings that permit h igh axial and radial forces.
Curve " " shows max. radial shaft load. Any shaft load exceeding the values quoted in the curve will seriously reduce motorlife. The two other curves apply to a B10 bearing life of 3000 hours at 200 RPM.

The M+S Hydraulic Hydrostatic Steering units are used in low-speed vehicles which drivingspeed does not exceed 60 km/h - such as: building machines, fork-lift trucks, harvestingmachines, off-highway equipment and others. These hydraulic units amplify the torque to thesteering wheels, with no need of hard mechanical connection.The XY hydrostatic steering unit incorporates an axially displaced tracing valve and a metering
pump in one housing. The working liqid is supplied by a separate pump and then is directed bythe metering pump to the steering cylinders.The XY steering unit is manufactured wiht a built-in check valves, and there is an option for a
built-in relief valve in the inlet.

HYDROSTATIC STEERING UNIT TYPE HKU.../7
"Closed Center - Non Load Reaction"Version 7 - HKU.../7
The HKU.../7 is a hydrostatic steering unit, designed for integration into systems withbuilt-in hydroaccumulator, achieving minimal energy losses.
"Closed Center - Non Load Reaction"
When connecting to a differential cylinder the L and Rports of the steering unit must be connected as follows: L tothe greater piston area, and R - to the smaller one.
For the andsteering units is
possible to observe Thermal Shock - condition caused whenthe hydraulic system has operated for some time withoutturning the steering wheel, causing the fluid in the reservoirand the system to heet up while the steering unit is relativelycool (i.e. there is more than 50 F [10 C] difference in thetemperature). If, under the condition of Thermal Shock, thesteering wheel is turned very quickly, it is possible to expe-rience temporary seizure and have the internal parts of thesteering unit damaged. The temporary seizure may befollowed by a total free wheeling.

HKUQ.../4 is a new series of hydrostatic steering units with an additionallyincreased flow. The hydrostatic steering unit type HKUQ…/4 is available for steeringmedium and large sized vehicles, allowing easy control either in servo-amplifiedmode or in emergency operation.
HKUQ…/4 is an “Open Center-Non Load Reaction” hydrostatic steering in whichrestrictor for amplifying factor from 1,3 to 2,5 is built-in.
In accordance with the size of the gear wheel set and amplifying factor, HKUQ…4has the following working volume:
- from 80 cm to 200 cm for emergency operation mode (manual steering withoutservo-amplifying;
- from 100 cm to 500 cm for normal operation mode ( with total flow amplifying).There is no servo-amplifying of flow if low steering speed till 10 min is applied. In
steering speed increase over 20 min there is total servo-amplifying of flow. In thismode gear wheel set flow and restrictor flow are added.

The HKU(S).../5(T)(E)(TE) range expands the steering units family of M+S Hydraulic withthe (static hydraulicconnection to the priority valve)This range is manufactured in two versions; for modularly and pipe mounting and
therefore were developed the two versions of priority (tracing) valves: PRD... and PRT...HKU.../5 is designed to be connected with priority valves with built-in relief valves for
rated flow up to 160 l/min.The control hydraulic circuits of the HKU(S).../5(T)(E)(TE) steering units were designed to
ensures minimal energy consumption (energy losses) in various hydraulic systems such asthose of: fork-lift trucks, agricultural and construction machines and others.
The HKUS.../5E and HKUS.../5TE are equipped with an electrohydraulic relay,mounted in the EL port, which supplies signal to the electric - control system. The relay canbe pre-set to normally - open (N.O) or normally - closed (N.C) contacts, with controlrange from 0,1 to 50 bars. Upon customer's request the relay could be supplied withanother type of fixing thread.*For operation in condition of Thermal Shock see the notes on page 6.

The M+S Hydraulic BKH valves are developed to protect thecomponents of the hydraulic circuit: pumps, steering units andcylinders - from overloads, impacts and cavitation. Some of theiradvantages are: easy integration into any hydraulic circuit, easymounting to the steering unit, and quick and easy hose connections.Depending on the design and the built in valves the BKH valves can bedivided into 6 types: BKH1 ... BKH5 and BKHR, with BKH5 designedfor XY steering units only. The maximum flow rate is in compliance withthe whole range of HKU and XY steering units but no more than 80l/min. The pressure settings for the entry relief valves and the shockvalves are given in the table.

PRIORITY VALVES FOR HKUS.../5... TYPE PR...
The Priority Valves distribute and trace the hydraulic flow from the supply pump of thehydraulic system to the hydraulic components which control and run the vehicle.The Priority Valves are used only with the HKUS.../5(E)(T)(TE) hydrostatic steering units.
When connected, the steering unit and the priority valve represent sophisticated hydraulictracing system that controls the flow in both main pipelines of the hydraulic system (theworking and control one) at any time of its operation.
As a static signal, the "LS" signal must be used in systems with circuit stability. Theconnection between the PRT, PRTA priority valves and the HKUS.../5T(TE) steering unitshas to be as short as possible, but should not exceed 1,5m (for iron pipe with ø4internal diameter). When a rubber hose is used this length have to be even shorter.
* Connection to the HKUS.../5... is done with 2 screws M10x1x45-10.9 DIN 912 orwith 2 screws 3/8-24 UNF ANSI B18.3-76; 44,5 mm long.Tightening torque: 4,5±0,5 daNm.

UVM...
P T
The M+S Hydraulic UVM Torque Amplifiers amplify the applied torque to the controlshaft and thus ease the running of various transport vehicles such as:
-agricultural and wood working machines;
-road rollers and road cleaning machines;
-fork-lift trucks and construction machinery;
The totally transferred power in terms of output torque is up to 1,1 kW.
The UVM torque amplifiers with their simple design, consisted of a pump and anamplifier, ensure 40 times higher output torque than the applied one. The amplifying isachieved as follows; by rotating the input shaft to the left or right the spool and the bushingare displaced, and the hydraulic flow enters the system turning the gerotor set, whichtransfers the already amplified torque to the output shaft.
One advantage of the UVM torque amplifier is that it allows manual steering in cases ofengine (pump) failure.

GENERAL INFORMATION
FLUID DATA:
Note:
To insure maximum performance and life of the Hydrostaticsteering units, use premium quality hydraulic oils. Fluids witheffective quantities of anti-wear agents or additives arehighly recommended. If using synthetic fluids consult thefactory for alternative seal materials.
Normal operating temperature range from +30 Cto+60 C.Minimum operating temperature -40 C.Maximum operating temperature +80 C.
Extended periods of operation at temperature of 60 Cand above will greatly reduce life of oil due tooxidation and shorten life of product.

MOUNTING UNITSAll hydrostatic steering units should be installed for ease of
access. It is recommended that the steering unit be located
outside the vehicle cabin.It is important that no radial axial load be applied to the
hydrostatic steering unit input shaft. Any or all radial and
axial loads must be absorbed by the steering column or
other operating device supplied by the vehicle
manufacture.Ports on the steering cylinder(s) should face upward to
prevent damage.During installation of the hydrostatic steering unit,
cleanliness is of the utmost importance. Pipe plugs should
be left in place during mounting and only removed when
hydraulic lines are to be connected.
� Filtration
The maximum degree of contamination per ISO 4406 or
CETOP RP is:-20/17 open center units-19/16 closed center and load sensing-16/12 priority valvesReturn line filtration of 25 m nominal (40 - 50 m absolute)
or finer is recommended.In extremely dusty conditions filtration of 10 m absolute
should be used.
� �
�
START UPAll air must be purged from system before operating unit. It is
extremely important that any external lines or units with load
sensing or priority feature be completely bled. Lines going to
and from cylinders as well as lines to and from pump be
purged of all air. It is recommended that a 10 - 15 mm filter
be used between pump and steering unit before start up.
