Compact hydraulic power pack type HK 3.. Type HK 34 nominal power 1.1 kW Type HK 33 nominal power 0.8 kW Fan cooled, for continuous and intermittent service; single circuit pump For higher power demand see For lower power demand (only single circuit pumps) see Delivery flows: 0.9 ... 6.5 l/min Operating pressure: 700 ... 45 bar General description and information Terminal box with cable gland M20x1.5. Six pin terminal strip enables the customer to connect either in !-mode (standard) for 3 x 400V 50 Hz or /-mode for 3 x 230V 50 Hz. Additional terminal strip for optional float switch or temperature switch. Two different designs are available for the filler neck; There is also a screen filter 0.4 x 0.22 installed in the bearing housing. Filling gauge with Max./min. - marking Bottom housing section with radial piston pump for pressure ranges up to 700 bar or play compensated gear pump for pressure ranges up to 170 bar and stator (shrunken in) as well as armature of the drive motor. Drive motor lay-out for 3+400/230V 50 Hz!/ (IEC 38) as standard, nominal power 1.1 or 0.8 kW. Further nom. voltages possible e.g. for 500V 50 Hz, 220V 60 Hz. Finned tubular tank with fluid level gauge (Plexiglas tube) and alternatively with temperature switch. It is connected via a press fit with the bottom housing where the stator shrunk in. This helps to conduct the generated heat from the armature to the cooling fins. Second or auxiliary pedestal with optional reflow port. Main connection pedestal with one pressurized oil outlet and reflow inlet port. Prepared for the mounting of connection blocks for ongoing pressure and reflow pipes or with directly mounted directional valve banks (illustrated). HAWE HYDRAULIK GMBH & CO. KG STREITFELDSTR. 25 • 81673 MÜNCHEN © 1991 by HAWE Hydraulik Top cover (bearing carrier) with upper bearing of the shaft, oil filler neck (see fluid fill-up) breather, leads connection stator winding → terminal enclosure (see there). Fan shroud with largely dimensioned fan wheel. The complete upper section is also available rotated by 3x90° in relation to the bottom section. The fan shroud directs the stream of air, which is created by the fan wheel, through the ribs and thereby ensures an intensive heat dissipation to the surroundings. These compact hydraulic power packs are therefore suitable for the VDE 0530 operating modes S1 (continuous operation) in the range of the nominal power as well as S6 (permanent running with idle sequences). Thereby approx. up to 1.8 of the nom. power rating can be employed. S3 (intermittent service) is also possible. The cooling effect of the large finned surface is also very good at standstill of the motor. The pump section is easily accessible from the underside after removing the bottom cover, e.g. for maintenance. D 7600-3 Compact-hydraulic power pack HK 3.. November 1997-05

Open the catalog to page 4Further characteristic data General information Nomenclature Constant delivery pump Valve controlled radial piston pump or play compensated gear pump (with external toothing) Arbitrary for radial piston pumps (version H..), delivery flow direction remains the same. Versions with gear pumps ( coding Z... ) must rotate anti clockwise always. It is therefore necessary to check the rotation direction of the motor. The fan wheel has to rotate anti clockwise after starting the motor when looking through the perforation of the fan shroud. The connection of two of the three main wires has to be...
