Hydraulic power packs type HKL and HKLW For 1+ and 3+phase mains Fan cooled, for continuous and intermittent service; single and dual circuit pumps Compact hydraulic power packs for vertical installation: HK 2 D 7600-2 HK 3 D 7600-3 HK 4 and HKF 4 D 7600-4 KA 2 D 8010 KA 4 D 8010-4 MPN D 7207 Flow Qmax Pressure pmax = approx. 22 lpm (1450 rpm) = 700 bar (Radial piston pump) = 200 bar (Gear pump) Basic layout Terminal box with cable gland M20x1.5. Additional terminal strip for optional float and/or temperature switch. There is also a version with central plug (Co. HARTING). Main connection pedestal with one (single circuit pump) or two pressure outlets (dual circuit pump) and return port. Prepared (interface) for the mounting of connection blocks for ongoing pressure and return pipes or with directly mounted directional valve banks (acc. to D 6905 ++). Filler neck with breather screen filter 0.4 x 0.22 Filling gauge with Max./Min.– marking Bottom housing section with radial piston pump for pressure ranges up to 700 bar or gear pump for pressure ranges up to 200 bar. Table of contents Finned tubular tank with shrunk-in stator. This helps to conduct the generated heat from the winding to the cooling fins. Fan shroud with largely dimensioned fan wheel. 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 operating modes S1 (continuous operation) in the range of the nominal power as well as S6 (permanent running with idle sequences) conf. VDE 0530. 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. Hydraulic power pack Type HKL 3 September 2009-03
