Product Overview

Series capability and selection context

Custom hydraulic power units (hydraulic stations) built for your actuators: pump, motor, tank, valves, filters and cooler matched to pressure, flow and duty.

Matched hydraulic power source

Pump flow, operating pressure, motor power, tank volume and control logic can be configured for the equipment.

Integrated auxiliary functions

Cooling, filtration, brake release, lubrication and control-valve functions can be combined in one package.

Built around installation limits

Frame, tank, manifold and electrical control layout can be adapted to available space and service access.

Configuration Reference

Verified configuration choices

Final sizing, configuration and interface require JST engineering confirmation.

Electric motor	Voltage, power, duty cycle and protection grade
Hydraulic pump	Gear pump, vane pump or piston pump according to pressure and flow
Oil tank	Volume, mounting, cleaning access and heat dissipation
Manifold and valves	Pressure control, flow control, directional control and load-holding logic
Filtration	Suction, return or pressure filters for oil cleanliness
Cooling	Air cooler or water cooler for high-duty operation
Accessories	Hoses, couplings, gauges, sensors, breathers and fittings

Applications

Typical applications

Hydraulic winch, wheel drive and slewing drive power supply
Industrial presses, test benches and machine tools
Construction, agricultural, mining and forestry machinery
Marine deck equipment and offshore hydraulic systems
OEM hydraulic equipment and compact power packs
Brake release, lubrication, cooling and auxiliary hydraulic circuits

Selection Guide

Information used for preliminary selection

Actuator requirement: confirm motor, cylinder, winch or drive functions powered by the unit.
Pressure and flow: define operating pressure, peak pressure, pump flow and required speed.
Power source: confirm electric motor voltage, frequency, power limit or engine-driven requirement.
Tank volume: select oil tank size based on flow, heat generation, duty cycle and installation space.
Valve control: specify relief valve, directional valve, counterbalance valve, proportional valve or custom cartridge valve manifold block.
Filtration and cooling: choose suction filter, return filter, pressure filter, air cooler or water cooler as needed.
Monitoring: define pressure gauge, temperature sensor, level switch, pressure switch and electrical control needs.
Compact hydraulic power pack or skid-mounted hydraulic station.

Engineering Notes

Series-specific review points

Product type: Hydraulic power unit / hydraulic power pack / hydraulic station.
Main components: Electric motor, pump, tank, manifold, valves, filters, cooler and accessories.
Pressure and flow: Configured according to actuator requirement and duty cycle.
Power source: Electric motor voltage and power selected by application.
Controls: Manual, electrical, sensor feedback or PLC-compatible options.
Customization: Tank, pump, valve logic, cooling, filtration, frame and accessory options.

Final sizing, configuration and interface require JST engineering confirmation.

OEM & Custom Builds

Custom and OEM hydraulic power units

For OEM equipment builders, JST configures the hydraulic station around the machine rather than offering a fixed catalog unit. The electric motor, pump, oil tank, manifold, filtration, cooling and frame are matched to the actuators the unit will drive and to the space available on the machine.

Build Scope

What is configured for your machine

Built for the actuator: when the unit feeds a JSJ hydraulic winch, JNM or JHM motor, wheel drive or slewing drive, pressure, flow and brake-release functions are reviewed together with that drive.
Valve logic in one block: pressure, flow, directional and load-holding functions can be combined in a custom manifold block.
Fit to the machine: frame, tank, manifold and electrical control layout adapted to installation space and service access, as a compact power pack or skid-mounted station.
Engineering review first: send the duty and hydraulic data; installation drawings are supplied after the model and interface are reviewed.

For a winch application, start from the rope duty described in how to size a winch drive motor, then send the result with your selection review request.

FAQ

Hydraulic power unit questions

Can JST build a custom or OEM hydraulic power unit?

Yes. JST configures the electric motor, pump type, oil tank, manifold and valves, filtration, cooling, frame and accessories around the actuators it will drive. Final sizing, configuration and interface are confirmed by JST engineering.

What information is needed to quote a hydraulic power unit?

The actuators to be powered (motor, cylinder, winch or drive), operating and peak pressure, pump flow and required speed, electric motor voltage, frequency and power limit, duty cycle, valve functions, filtration and cooling needs, monitoring and control requirements, and the available installation space.

Which pump does a hydraulic station use?

A gear pump, vane pump or piston pump is selected according to the required pressure and flow. The choice is confirmed during the engineering review.

Can the power unit be supplied together with a JST winch or motor?

Yes. Power units are used to supply hydraulic winches, wheel drives and slewing drives, and can integrate brake release, lubrication and cooling circuits, so the unit can be reviewed with the JST motor, winch or manifold it will feed.
