Hydraulic Power Unit Oil‑immersed Motor
- Oil‑cooled AC motor lowers noise and enhances thermal stability for continuous duty
- Compact motor‑pump integration reduces footprint and simplifies installation
- Single‑acting ramp and double‑acting lip circuits for precise dock leveler control
- AC 110/120/230/240/400V options to match regional power standards
- Aluminum central manifold with cartridge valves for robust control and serviceability
- Plastic or steel reservoirs sized for proper recirculation and cooling
- Pressure, flow, and leak‑tested assemblies for reliable startup
- Clean routing and fewer external components for easier maintenance and lower lifecycle cost
Oil‑immersed Motor Hydraulic Power Units deliver stable hydraulic power with lower noise and better thermal performance.
The electric motor runs submerged in clean hydraulic oil, improving heat dissipation and acoustic damping while keeping the package compact.
This design suits dock levelers, lift tables, and indoor industrial equipment where continuous duty, predictable uptime, and clean installation matter.
You get configurable single‑ or double‑acting circuits for ramp and lip control, with aluminum manifolds, quality pumps, and tested assemblies that integrate quickly into your system.
