The <\/span><\/span>CraftOil HHB-700AB double-acting hydraulic power unit<\/b><\/span><\/span> is designed to operate hydraulic cylinders that require pressurized oil to extend and retract the piston rod. Its two working lines, A and B, allow hydraulic pressure to be directed alternately to the cylinder’s two chambers, providing controlled movement in both directions.<\/span><\/span><\/p>\n

With a maximum operating pressure of 70 MPa (700 bar), a 0.75 kW electric motor and a 7-litre oil tank, the HHB-700AB is suitable for compatible high-pressure hydraulic equipment used in workshops, industrial facilities, maintenance operations and installation work.<\/span><\/span><\/p>\n

The two-stage pump delivers a higher oil flow at low pressure for faster initial movement and switches to the high-pressure stage as resistance increases. The unit operates from a standard 220V single-phase power supply and includes a remote control for convenient operation.<\/span><\/span><\/p>\n

Double-Acting vs. Single-Acting Hydraulic Power Units<\/b><\/span><\/span><\/p>\n

The main difference between the HHB-700AB and the DYB-63A or DYB-63H models is the hydraulic circuit configuration.<\/span><\/span><\/p>\n\n\n\n\n\n\n\n\n\n\n

When Do You Need a Double-Acting Hydraulic Power Unit?<\/b><\/span><\/span><\/p>\n

The HHB-700AB is worth considering when:<\/span><\/span><\/p>\n

    \n
  • \n

    Your hydraulic cylinder has two hydraulic ports and requires pressure in both chambers.<\/span><\/span><\/p>\n<\/li>\n

  • \n

    The piston rod must retract under hydraulic power instead of relying on a spring or gravity.<\/span><\/span><\/p>\n<\/li>\n

  • \n

    You need predictable, controlled movement in both directions.<\/span><\/span><\/p>\n<\/li>\n

  • \n

    Your equipment requires powered retraction during repetitive operating cycles.<\/span><\/span><\/p>\n<\/li>\n

  • \n

    You operate compatible pipe benders, hydraulic pullers, presses or other machinery requiring a double-acting cylinder.<\/span><\/span><\/p>\n<\/li>\n<\/ul>\n

    When Is a Single-Acting Unit Enough?<\/b><\/span><\/span><\/p>\n

    If your cylinder has one hydraulic port and returns through a spring, gravity or another designed return mechanism, a single-acting power unit may be sufficient.<\/span><\/span><\/p>\n

    A double-acting unit adds complexity and cost, so it is not automatically the best choice for every application. Contact CraftOil with your cylinder specifications, and we will help you determine which configuration suits your equipment.<\/span><\/span><\/p>\n

    Important:<\/b><\/span><\/span> The power unit’s maximum operating pressure is 700 bar. The 1,000 bar gauge scale does not increase the unit’s pressure rating. Always follow the pressure limits of the connected cylinder, hoses, fittings and other components.<\/span><\/span><\/p>\n

    Remote Control for Convenient Operation<\/b><\/span><\/span><\/p>\n

    The remote control allows the operator to start and stop the power unit without having to stand next to its housing. This makes operation more convenient and helps the operator remain focused on the workpiece and equipment.<\/span><\/span><\/p>\n

    Always keep a safe distance from moving parts and pressurized hydraulic connections. A remote control does not replace appropriate safety procedures.<\/span><\/span><\/p>\n

    Why Does the Pressure Gauge Have a 1,000 Bar Scale?<\/b><\/span><\/span><\/p>\n

    The glycerine-filled pressure gauge has a scale extending to 1,000 bar, while the power unit is rated for a maximum operating pressure of 700 bar.<\/span><\/span><\/p>\n

    Glycerine helps dampen needle vibration, making readings easier to observe during operation. The gauge scale is an indication range, not permission to operate the hydraulic system above its rated pressure.<\/span><\/span><\/p>\n

                Safety and Operating Recommendations<\/b><\/span><\/span><\/p>\n

                Hydraulic systems operating at 700 bar require appropriate installation, inspection and operating procedures.<\/span><\/span><\/p>\n

                  \n
                • \n

                  Inspect hydraulic hoses, fittings and couplings before use. Replace damaged or leaking components immediately.<\/span><\/span><\/p>\n<\/li>\n

                • \n

                  Connect the A and B hydraulic lines according to the equipment diagram. Incorrect connections can cause unexpected cylinder movement.<\/span><\/span><\/p>\n<\/li>\n

                • \n

                  Never exceed the rated pressure of the power unit or any connected component.<\/span><\/span><\/p>\n<\/li>\n

                • \n

                  Never disconnect a quick-release coupling while the system is pressurized.<\/span><\/span><\/p>\n<\/li>\n

                • \n

                  Wear appropriate eye protection and keep hands away from leaks and pressurized connections. High-pressure oil can cause serious injection injuries.<\/span><\/span><\/p>\n<\/li>\n

                • \n

                  Monitor oil temperature during extended operation.<\/span><\/span><\/p>\n<\/li>\n

                • \n

                  Use a correctly grounded, suitable 220V power supply.<\/span><\/span><\/p>\n<\/li>\n

                • \n

                  Follow the operating manual and depressurize the system before maintenance.<\/span><\/span><\/p>\n<\/li>\n<\/ul>\n

                  Safety reminder:<\/b><\/span><\/span> Never use your hands to search for a hydraulic oil leak. If a high-pressure injection injury is suspected, seek emergency medical attention immediately, even if the wound appears small.<\/span><\/span><\/p>\n

                    Frequently Asked Questions<\/b><\/span><\/span><\/p>\n

                    What is a double-acting hydraulic power unit?<\/b><\/span><\/span><\/p>\n

                    A double-acting hydraulic power unit supplies pressurized oil to either of the two chambers of a compatible hydraulic cylinder. This allows the piston rod to extend and retract under hydraulic pressure.<\/span><\/span><\/p>\n

                    What is the difference between the HHB-700AB and the DYB-63A?<\/b><\/span><\/span><\/p>\n

                    The principal difference is the hydraulic circuit. The HHB-700AB is designed for double-acting cylinders and includes a remote control. The DYB-63A is a single-acting unit intended for compatible cylinders with a designed return mechanism. Their listed pressure, motor power, flow rates, tank capacity and weight are the same.<\/span><\/span><\/p>\n

                    How can I identify a double-acting hydraulic cylinder?<\/b><\/span><\/span><\/p>\n

                    A double-acting cylinder commonly has two hydraulic ports, allowing oil to enter either chamber. A single-acting cylinder commonly has one pressure port and returns through a spring, gravity or another designed mechanism. Check the manufacturer’s documentation rather than relying on port count alone.<\/span><\/span><\/p>\n

                    Does the HHB-700AB work from a standard electrical outlet?<\/b><\/span><\/span><\/p>\n

                    It is specified for a 220V single-phase power supply. Confirm that the outlet, wiring, grounding and electrical protection are suitable for the motor and installation.<\/span><\/span><\/p>\n

                    What is the maximum operating pressure?<\/b><\/span><\/span><\/p>\n

                    The maximum specified operating pressure is 70 MPa (700 bar). The pressure rating of the connected cylinder, hose, fittings and other components must also be suitable for the system’s operating pressure.<\/span><\/span><\/p>\n

                    Why is the pressure gauge rated up to 1,000 bar?<\/b><\/span><\/span><\/p>\n

                    The gauge has a 1,000 bar measurement scale, while the power unit is rated for up to 700 bar. Glycerine dampens needle vibration. The gauge rating does not increase the permissible operating pressure of the power unit.<\/span><\/span><\/p>\n

                    Is hydraulic oil included?<\/b><\/span><\/span><\/p>\n

                    No. Hydraulic oil must be purchased separately and selected according to the equipment manual and operating conditions.<\/span><\/span><\/p>\n

                    What warranty does CraftOil provide?<\/b><\/span><\/span><\/p>\n

                    The supplied product information specifies a three-month warranty. Contact CraftOil for details of warranty coverage and service conditions.<\/span><\/span><\/p>\n

                    Can CraftOil help me choose the correct power unit?<\/b><\/span><\/span><\/p>\n

                    Yes. Send us the cylinder specifications, photos of the connections and details of your application. We can help assess whether the HHB-700AB or another hydraulic power unit is the more appropriate choice.<\/span><\/span><\/p>\n

                    Order the HHB-700AB Hydraulic Power Unit from CraftOil<\/b><\/span><\/span><\/p>\n
