Snowplow hydraulic pumps convert motor or engine power into hydraulic pressure, enabling the blade to lift, lower, angle left or right, and float along the road surface. Choosing the right pump requires confirming voltage, pressure, flow rate, reservoir capacity, valve function, and mounting space.
For bulk supply or custom specifications, you can review our snow plow power unit product options and compare key selection points below.
How Does a Snow Plow Hydraulic System Work?
Snowplow hydraulic systems convert electrical power into hydraulic pressure. In modern truck-mounted setups, a 12V DC motor drives a gear pump, which draws oil from the reservoir and sends pressurized fluid through a valve block to lift and angle cylinders.
- 1
Lift blade: Motor starts, pump builds pressure, oil enters lift cylinder to raise blade.
- 2
Lower blade: Valve opens, allowing oil return; gravity often assists lowering.
- 3
Angle left or right: Oil directed to one angle cylinder while the opposite side returns to the reservoir.
- 4
Float function: Blade can follow the ground surface rather than staying locked.
Key Specifications and Hydraulic Circuit Diagram
When selecting a snowplow hydraulic pump, confirm the main specifications with your equipment model, blade size, and control requirements. Reference the parameters below and the provided hydraulic circuit diagram. For custom needs, contact us to match your specific requirements.
What Components Are Included in a Snow Plow Power Unit?
A snow plow power unit often includes more than just the pump. For replacement or OEM production, the full assembly structure should be confirmed before ordering.
- 1
DC motor: Drives the hydraulic pump.
- 2
Gear pump: Draws and pressurizes oil.
- 3
Reservoir: Stores hydraulic fluid.
- 4
Valve block: Directs oil for lift, lower, angle, float.
- 5
Relief valve: Protects against overpressure.
- 6
Solenoid valve: Receives cab control signals.
- 7
Ports and fittings: Connect hoses to cylinders.
If voltage, pressure, flow, tank size, and valve function are confirmed, you can send your snow plow power unit requirements to Jade Crown for specification matching.

Common Failure Signs and Maintenance Tips
Before replacing a snowplow hydraulic pump, check whether the problem comes from the pump, oil, valve block, wiring, filter, or cylinder. Many issues arise from contaminated oil, thickened oil in low temperatures, trapped air, or blocked filters.
- 1
Whining or screaming noise: Caused by thick oil, air, cavitation, or pump wear.
- 2
Weak lifting: Worn gears, low oil, pressure loss, or relief valve issues.
- 3
Blade does not move: Electrical faults, solenoid failure, frozen oil, or valve blockage.
- 4
Slow angle movement: Low flow, old oil, clogged filter, cylinder resistance.
- 5
Oil leakage: Inspect seals, hoses, reservoir, valve block, and cylinder connections.
How to Maintain the Hydraulic System
Snowplow equipment works in harsh environments, so regular oil maintenance is crucial for system performance and service life.
- Use low-temperature hydraulic oil suitable for snow plow applications.
- Change oil regularly before winter.
- Clean suction filter; remove metal particles from magnet if equipped.
- Check hose connections and wiring before installation.
- After adding new oil, cycle blade left/right/up/down to purge air.
- Check oil level with blade lowered; avoid overfilling.
