The 2.2KW Low Noise Hydraulic Power Pack for Home Lift (Model EM21-6900-1) is a compact hydraulic power unit manufactured by EONMACH for residential lifting applications. The unit integrates a 2.2KW electric motor, gear pump, multifunctional manifold with 24V solenoid valves, a two-speed descent valve, a manual hand pump for emergency operation, and a 35L steel oil tank into a single assembly. The pump adopts an oil-immersed design, where the hydraulic pump operates submerged in oil to reduce operational noise and vibration. The power pack is suited for home elevators, residential garage lifts, hydraulic door systems, and other light-duty residential hydraulic equipment. Business buyers should note that the motor is configured for three-phase 220V or 380V power supply, which may require an electrical upgrade in standard residential settings.
The hydraulic pump is mounted inside the oil tank and operates submerged in hydraulic fluid. This oil-immersed arrangement dampens pump-generated noise and vibration at the source, reducing sound transmission to the surrounding environment compared with conventional externally mounted pump configurations. The design also eliminates the need for a separate pump coupling and reduces the number of external leak points.
The unit is driven by a 2.2KW (3HP) dual-voltage three-phase electric motor (220V / 380V). The hydraulic circuit includes 24V DC solenoid directional valves for lift and lower control, a two-speed descent valve that provides a fast approach speed and a slow leveling speed for smooth landing, and a manual hand pump that allows emergency lowering or lifting in the event of a power outage. The standard oil tank capacity is 35L.
The power pack features a vertically oriented tank-and-motor arrangement with a compact footprint, allowing installation in basement corners, equipment rooms, elevator shafts, and garage utility spaces. The unit can be configured for vertical or horizontal mounting to suit available space. The manifold block incorporates standard hydraulic port connections for straightforward integration with lift cylinders and hydraulic piping.
The oil-immersed pump design reduces the number of external rotating components and leak paths, contributing to lower routine maintenance requirements. The oil tank is fitted with an accessible filler cap and a level gauge for oil inspection. The unit includes a pressure relief valve that limits maximum system pressure to protect the motor, pump, and connected hydraulic components from overload damage. Hydraulic oil must be 32# anti-wear hydraulic oil with a cleanliness rating of NAS 8-10, as specified by the manufacturer.

The power pack provides hydraulic power for residential elevators and home lifts, delivering controlled lifting and lowering through the solenoid valve manifold. The two-speed descent function enables a fast travel speed followed by a slow leveling speed near the floor, supporting smooth and accurate landing. The oil-immersed pump design helps keep operational noise within levels acceptable for residential environments.
The unit can power two-post and four-post car lifts, platform lifts, and storage lifting systems in residential garages. The 2.2KW motor and available pump displacements (8ml/r to 12ml/r for the 2.2KW configuration) provide sufficient flow for light-duty vehicle lifting. The compact footprint allows installation alongside garage equipment without occupying excessive floor space.
For large residential gates, sectional garage doors, and hydraulic entry systems, the power pack delivers consistent hydraulic flow for smooth opening and closing operation. The 24V solenoid control can be integrated with access control systems and remote controls for automated operation.
The power pack can also be used in hydraulic-driven storage lifts, small-scale home workshop equipment, and residential gardening lifting tools, providing a self-contained hydraulic power source for diverse household applications. Custom configurations for pump displacement, motor power, and tank capacity are available through EONMACH sales engineers.
The power pack is designed for residential hydraulic applications within its 2.2KW power rating and the flow and pressure ranges listed in the specifications table. It is compatible with common home hydraulic equipment such as small lifts, garage lifts, and hydraulic doors. However, the motor requires a three-phase 220V or 380V power supply, which is not standard in all residential properties. Business buyers should verify the available electrical supply and the required lift cylinder bore and stroke before ordering. For custom or specialized systems, consult EONMACH technical support to confirm compatibility.
Routine maintenance includes: checking the hydraulic oil level via the tank gauge and topping up as needed; inspecting all hydraulic connections and the manifold for external leaks; cleaning the exterior of the unit, particularly the motor cooling fins; and replacing the hydraulic oil at intervals recommended in the product manual. The manufacturer specifies 32# anti-wear hydraulic oil with a cleanliness rating of NAS 8-10. The oil-immersed pump design reduces the frequency of pump-specific maintenance compared with externally mounted pumps.
While the unit features a self-contained design with pre-assembled manifold and valving, hydraulic system installation requires professional knowledge of fluid dynamics, hydraulic piping, and electrical connections. The three-phase motor wiring must be configured correctly for the available voltage (220V or 380V), and incorrect wiring can damage the motor. EONMACH recommends installation by a qualified hydraulic technician or licensed electrician. A detailed installation guide is provided with the unit to assist the installing technician.
Yes, EONMACH offers customization options including alternative pump displacements (6ml/r to 28ml/r), motor power ratings (1.5KW to 5.5KW), tank capacities, mounting orientations (vertical or horizontal), control voltage options, and additional safety features. Business buyers with specific flow, pressure, or space requirements should contact the EONMACH sales team with their application parameters to receive a configured quotation.
The power pack is equipped with a pressure relief valve that limits maximum system pressure to protect the motor, pump, and connected hydraulic components from overload damage. The unit includes a manual hand pump for emergency lifting or lowering in the event of a power outage. The two-speed descent valve provides controlled deceleration near the end of the lowering stroke. For additional safety options such as load-holding valves or burst protection, business buyers should consult EONMACH technical support.
