Choose a liftgate hydraulic pump by matching the original voltage, operating type, pressure, flow rate, reservoir, hydraulic ports and mounting dimensions. This guide explains the main configurations, replacement requirements and specifications available from Jade Crown Hydraulic. You can view our liftgate hydraulic pump range while checking your existing unit.
What Is a Liftgate Hydraulic Pump?
A liftgate hydraulic pump converts electrical power into hydraulic pressure to operate a vehicle-mounted lifting platform. A complete liftgate hydraulic power unit normally includes an electric motor, gear pump, reservoir, solenoid and control valves.
The same assembly may also be called a liftgate power unit. In some markets, tailgate hydraulic pump is used for a similar commercial vehicle product.
How Does a Liftgate Hydraulic Pump Work?
When the motor starts, it drives the hydraulic pump and sends pressurized oil from the reservoir to the cylinder. The cylinder then raises or lowers the platform according to the valve circuit.
A relief valve limits maximum pressure, while check valves and solenoid valves control oil direction and help hold the platform in position.
Which Operating Type Does Your Liftgate Need?
The operating type must match the original cylinder and hydraulic circuit.
- 1Power up / gravity down: Hydraulic pressure raises the platform, and gravity lowers it.
- 2Power up / power down: Hydraulic pressure controls movement in both directions.
- 3Single-acting: Oil enters one cylinder port.
- 4Double-acting: Oil alternately enters two cylinder ports.
A single-acting unit should not replace a double-acting system unless the cylinder and valve circuit are also changed.
Which Specifications Must Match Before Replacement?
A replacement liftgate hydraulic pump should be confirmed according to the following key information:
| Item | What to Confirm |
|---|---|
| Power and circuit | Voltage, single-acting or double-acting |
| Hydraulic output | Required pressure and flow rate |
| Reservoir | Capacity and mounting direction |
| Connections | Port thread, position and hose layout |
| Installation | Overall dimensions and control wiring |
Providing the original part number, nameplate photo and clear product images helps us confirm the configuration more accurately. You can submit your liftgate hydraulic pump parameters for fitment confirmation and receive further selection support.
Can It Replace Maxon or Waltco Liftgate Pumps?
A replacement unit may be used with an existing branded liftgate after all important parameters have been confirmed.
A replacement for a Waltco liftgate hydraulic pump must match the original voltage, operating type, pressure, ports and installation dimensions. The same checks are required when replacing a Maxon liftgate hydraulic pump.
The brand name alone cannot confirm compatibility because different models may use different motors, valves, reservoirs and hydraulic circuits.
What Specifications Does Jade Crown Hydraulic Offer?
Jade Crown Hydraulic provides standard and customized hydraulic power units within the following range:
| Specification | Available Range |
|---|---|
| Voltage | 12V / 24V DC, 110V / 220V AC |
| Flow Rate | 1.0-5.0 L/min |
| Pressure | Up to 16 MPa |
| Acting Type | Single-acting / Double-acting |
| Reservoir Capacity | 3L-10L |
| Mounting Options | Horizontal / Vertical |
| Remote Control | Wired / Wireless optional |
The 12V and 24V DC options are commonly used for vehicle-mounted liftgates. The 110V and 220V AC versions are available for special or stationary hydraulic equipment.
What Should Be Checked Before Replacing the Unit?
A platform failure may also be caused by low battery voltage, damaged wiring, a faulty solenoid, low hydraulic fluid or cylinder leakage.
Before replacing the complete unit, check:
- 1Battery voltage and grounding
- 2Switches, cables and solenoids
- 3Hydraulic oil level
- 4Hoses, fittings and cylinders
- 5System pressure
These checks can help avoid replacing a working liftgate hydraulic pump.

Frequently Asked Questions
How Do I Know If a Liftgate Hydraulic Pump Is Bad?
Check the battery, wiring, solenoid, oil level and external leakage first. Pump wear is more likely when the motor runs normally but the system cannot build sufficient pressure.
What Hydraulic Fluid Should Be Used?
Follow the liftgate or power unit manufacturer’s recommendation. ISO VG 32 is common in moderate temperatures, while colder conditions may require lower-viscosity oil.
Can Only the Motor Be Replaced?
Yes, if the pump, valves, coupling and reservoir remain in good condition. The new motor must match the original voltage, shaft, rotation, power and mounting dimensions.
What Information Is Needed for Replacement?
Provide the liftgate model, original part number, voltage, operating type, pressure, flow, reservoir, port details, installation dimensions and product photos.
Send the original part number, photos, required quantity and operating parameters to contact the Jade Crown Hydraulic team for liftgate hydraulic pump technical advice and a quotation.
