1. General description and information
Main connection pedestal with one pressurized oil outlet(single circuit pump) or two pressurized oil outlets ( two-andtriple circuit pumps ) and reflow inlet port.Prepared for the mounting of connection blocks for ongoingpressure and reflow pipes or with directly mounted direc-tional valve banks (illustrated connection block with pressure limiting valve).
Bottom housing sectionwith radial piston pump forpressure ranges up to 700bar and/or play compensat-ed gear pump for pressureranges up to 170 bar andstator (shrunken in) as wellas armature of the drive motor.Drive motor lay-out for 3 + 400/230V 50 Hz !/( IEC 38 ) as standard, nom-inal power 2.2 or 1.5 kW.Further nom. voltages pos-sible e.g. for 500V 50 Hz,220V 60 Hz.
Second or auxiliary pedestal with a pressureoutlet port and a reflow port (dual and triple circuit pumps).Prepared for the mounting of a connectionblock similar to the main connection pedestal.
The pump section is easily accessible fromthe underside after removing the bottom cover, e.g. for maintenance.
Finned tube tank with fluid level gauge (Plexisglas tube) and alternatively with temperature switch. It is connected via apress fit w ith the bottom housing where thestator shrunk in. This helps to conduct thegenerated heat from the armature to thecooling fins.
Top cover (bearing carrier) with upper bearing of the shaft, oil filler neck (see fluidfill-up) breather, leads connection stator winding → terminal enclosure (see there).Fan shroud with largely dimensioned fanwheel. The complete upper section is alsoavailable rotated by 3x90° in relation to thebottom section.The fan shroud directs the stream of air,which is created by the fan wheel, throughthe ribs and thereby ensures an intensiveheat dissipation to the surroundings.These compact hydraulic power packs aretherefore suitable for the VDE 0530 operat-ing modes S1 (continuous operation) in therange of the nominal power as well as S6(permanent running with idle sequences).Thereby approx. up to 1.8 of the nom. pow-er rating can be employed. S3 (intermittentservice) is also possible. The cooling effectof the large finned surface is also very goodat standstill of the motor.An auxiliary blower, driven independently,may be integrated as option for temperaturesensitive applications (approx. 25% better cooling).
Terminal box with cable gland M20x1.5. Six pin terminal strip enables the customer to connect eitherin !-mode (standard) for 3 + 400V 50 Hz or /-modefor 3 + 230V 50 Hz.Additional terminal strip for optional float switch or temperature switch.

Table 3: Single circuit pumpGear pump for low and mid range pressure applications with a delivery flow according to the size.
2) An inertia excess temperature of approx. 50K can be expect with the max. permissible pressure mentioned in the tables 2 and 3, if p1 isnot exceeded in continuous operation S1 and the indicated load periods are apparent in the no-load/load operation S6-10 min. This temperature usually will be considerably lower in the practical case, see also section 5.3.These temperature figures do apply to usual operation, taking into consideration the unavoidable losses due to back pressure in pipesand valves. Additional losses caused by flow control valves, pressure control valves, orifices etc. may lead to a higher inertia excess temperature, depending on the time involved.
3) The middled pressure of subsequent load cycles (e.g. at accumulator charging operation) should not exceed 50... 60% of p1 to ensurean economic service life of the bearings.
4) Max. pressure depending on the displacement. The continuous pressure requirement should be below 100 bar, to ensure an economicservice life of the gear pump.
1) Reference value refering to a nominal speed of 1395 rpm with mainsfrequency 50 Hz or 1750 rpm with mains frequency 60 Hz. Deliveryflow reduction due to speed drop of the motor in the range of pmax,see also sect. 5.1.The delivery flow coding can be regarded as a rough reference value for the flow at mains frequency 50 Hz.

2.2.2 Dual circuit pumpThe following pump combinations are available:• Radial piston pump of (3-cyl.) - radial piston pump of (3-cyl.)• Radial piston pump of (3-cyl.) - gear pump• Gear pump - gear pumpThe pressurized oil outlets can be led either individually to the main and the secondary connectionpedestal or both are led to the main connection pedestal.Because both pump circuits always deliver simultaneously, it has to be made sure that both can beswitched individually via an idle circulation valve in idle circulation mode as soon as no pressurizedfluid is required from it. These idle circulation valves may be either part of the required connectionblock ( see section 5.6 ) or the subsequent directional valve bank.Versions H...-H... to Z...-Z... are mainly used for applications where the consumers of two individ-ual circuits are simultaneously operated. Versions HH.../... to ZZ.../... are mainly used for single circuits to enable stepwise velocity control of consumers, by switching the individual pump circuitsin or out of idle circulation mode.

2.2.3 Triple circuit pumps
This version is available as radial piston pump with 6 pump cylinders only. Always 2 are ledto the ports P1 and P3 (main connection pedestal) as well as P2 (secondary connection pedestal).Since all three pump circuits deliver always simultaneously, it has to be made sure that bothcan be switched individually via an idle circulation valve in idle circulation mode as soon asno pressurized fluid is required from it. These idle circulation valves may be either part of therequired connection block ( see section 5.6 ) or the subsequent directional valve bank.

It is therefore necessary to check the rotationdirection of the motor. The fan wheel has to rotate anti clockwiseafter starting the motor when looking through the perforation of thefan shroud. The connection of two of the three main wires has to beinterchanged at the terminal strip or the special plug CEE 17 (DIN 49462) should be used enabling these changes in the plug, ifthe direction of rotation is wrong.

The current consumption of the motor depends strongly on its load. The nominal figures of sect. 3.2 apply strictly to one operat-ing point only. The pumps may be operated continuously up to themax. pressure p1 stated in sect. 2.2. Up to 1.8 s of the nominalpower of the motor can be exploited during load / no load opera-tion. The increased heat built-up under these conditions gets intensively radiated during the idle periods (also see sect. 5.3).

The product of pVg (bar · cm3/rev) is laid off as abscissa in thesecurves. This makes a rough consideration possible for the currentand the delivery flow to be expected, which is sufficient undermost conditions.The respective load is determinating for the current consumptionof dual and triple circuit pumps. The performance of the individ-ual circuits has to be determined and added up. The current to be expected can be found via (pVg)calc. in the curves. The permissible limit figures for pressure p1, p2 and p3 should not be exceeded aren't even if e.g. the available motor output isn'tcompletely employed.

5.2 Motor protection circuitries, auxiliary blowers and EMC5.2.1 Protective motor switches
S1-operation:(for pressure≤ p1)
S1-operation:(for pressure ≤ pmax)
The bimetallic switch should be set for the corresponding current, required to achieve the adjusted pressure of thepressure limiting valve (see IM-(pVg)calc.- curve sect. 5.1), however not higher than the nom. current IN. This motorprotection covers only a possible mechanical blockade of the motor. The pressure limiting valve responses at pres-sure overload, without a rise beyond the corresponding motor current IM. The pump would run on and on, result-ing in an overheat after a certain time like any other hydraulic power pack of classic construction would do. Sucha pressure overload can occur either due to overload of a consumer or start against a stop. This can be immedi-ately identified as the consumer movement stops and also the idle signal would be missing (Idle circulation valve doesn't open in the idle periods). A permanent pressure monitoring via a pressure gauge helps to identify such amalfunction. It is therefore recommended to use a pressure switch for self-supervisioning of the idle periods especially for automatic, not permanently manned systems.
In most cases it is sufficient, to set the response current to approx. (0.85...0.9) of IN. This makes sure that on onehand the bimetallic switch does not trigger too early during normal operation but on the other hand the oil temper-ature doesn't rise too high due to a prolonged response time after the pressure limiting valve is in action. Malfunctions during idle circulation mode, like described for S1-operation, are more reliably and immediately detected by idle supervisioning.It has to be taken into account that these notes for adjustment only represent very coarse reference values and perhaps must be corrected a little during a definite test run of the system. This might occur e.g. if the actually required performance of the pump (in S6-operation) is higher than calculated. Too early triggering of the bimetallicswitch will be caused as the temperature of the system would be higher after prolonged operation than anticipat-ed thereby reducing the response period of the switch.
5.2.2 Temperature switch section 3.2
5.2.3 Float switch section 3.2
This is an optional monitoring device, which will cut-off the pump if the fluid temperature rises over 80°C due to any malfunction.Examples: A pump is running too long against the pressure limiting valve at a unmanned system because the signal for idle
circulation was not released. The response period will be too long due to the low current consumption. The ambient temperature is too high, because it was not considered during lay-out of the system or it occurs unintended.Too much heat is generated in the system because of additional throttle losses caused by flow control valves, pressure reducing valves, orifices etc. Attention: The temperature switch will trigger only after the oil temperature is above approx. 95°C.
This is an optional monitoring device, which will either cut-off the pump or trigger a signal as soon as the fluid level drops below acertain level. Examples: Line rapture will cause an immediate stop, preventing complete emptying of the tank and dry running of the pump.
A signal will be triggered if the system was not refilled after design related fluid losses. Attention: The signal has to be delayed sufficiently (time lag relay) if the lay-out of the system features an operation cycle where the pump is emptied below the min. level and replenished by the reflow from the consumerwithin one cycle.

The compact hydraulic power packs of HAWE are excluded from the EMC-regulation 89/336/EEC as they are no turn-key devices.We recommend to use the interference suppressors type 23140, 3 • 400VAC 4kW 50-60Hz of Murr-Elektronik in D-71570 Oppenweiler, if any interferences should occur.

5.4 Running noise
Measuring conditions Work room, interference level approx. 50 dB(A); Measuring point1m above the floor; 1m object clearance, pump fixedwith 4 silentblocs Ø 40 x 30 65 Shore, (Messrs. Schwingmetall No. 20291/V).Measuring device: Precision sound pressure levelmeasuring instrument DIN IEC651 Kl. IViscosity of the oil: Approx. 60 mm2/s
The sound pressure level ranges shall serve to estimate the running noise to be expected. They approximately delimit the spreadsrecognizable during measuring. Pumps with smaller delivery flows tend as a rule to the lower, whereas larger ones tend to the upper limit. The noise level of dual or triple circuit pumps are similar to the one of single circuit pumps, if the total delivery flow is similar.Rigid mounting on a surface capable of resonance (e.g. welded or thin-wall machine stands) may significantly amplify or conductthe operation noise level. We recommend to mount the compact hydraulic power pack via silentblocs e.g. Ø40x30, 65 Shore (see specifications of the measuring conditions).
5.5 Auxiliary tanksIt is possible to increase the usable volume byconnecting an auxiliary tank at port T. It shouldbe used for volume compensation only. Thesetanks are to be customer furnished. The reflowpipe from the consumer circuit has to be con-nected at port R (connection pedestal)!The connection pipe has to be dimensionedsufficiently. The connection should be eitherby means of a hose only or with fittings forpipe 22x1.5 and a piece of hose to decouplethe noise.

Integrated functional el-ements 12)
1) It should be kept in mind that the directional valve banks which can be directly mount-ed may have a max. permissible pressure below 700 bar.
2) Pumps type HK should be used for intermittent service only
3) The valves are directing radially to the outside
4) Hydraulic cut-off function acts as pressure limitation also
5) Depending on type also with additional proportional pressure limiting valve
6) Idle circulation valve acc. to D 7490/1 with AS..., acc. to D 7470B with AK... and AM...,with automatic idle circulation (accumulator charging valve) with AL21...
7) With pressure resistant filter at AL21D...
8) Directional spool valve banks type SWR.., SWS.. are not ideally suited for mounting onto blocks type AL11(12) or AL21.., as the their always apparent leakage would pro-voke permanent activation. This effect could be minimized by using an accumulator.
9) May be used as idle circulation valve if the prop. solenoid is deenergized (approx. 5 bar)
10) Depending on actuation and flow pattern
11) For directional spool valves with internal connection P → R in idle position
12) Pressure limiting valves acc. to D 7000E/1, 2/2-way directional valves acc. to D 7490/1,optional with additional check valve acc. to D 7445
