TRAILER HYDRAULIC PUMPS, CYLINDERS & HYDRAULIC COMPONENTS
IN PHOENIX, ARIZONA
Hydraulic systems are the driving force behind many dump trailers, hydraulic tilt trailers, deck-over trailers, roll-off trailers, and other specialized equipment trailers. Whether you're raising a dump bed, operating hydraulic ramps, extending a tilt deck, or powering auxiliary trailer equipment, your hydraulic system relies on properly matched pumps, cylinders, hoses, valves, and electrical components to operate safely and efficiently.
Deer Valley Trailer stocks a large selection of hydraulic pumps, hydraulic cylinders, reservoirs, hydraulic hoses, fittings, replacement motors, solenoids, remote controls, battery cables, hydraulic fluid, and related components for many trailer manufacturers. Whether you're replacing a failed hydraulic pump, diagnosing a slow dump bed, repairing a leaking cylinder, or building a custom hydraulic system, our knowledgeable parts specialists can help identify the correct replacement components for your trailer.
HOW A TRAILER HYDRAULIC SYSTEM WORKS
A trailer hydraulic system converts electrical energy into hydraulic pressure to move heavy loads with precision and control. When the hydraulic pump is activated, pressurized hydraulic fluid is directed through hoses and control valves into a hydraulic cylinder. As pressure builds, the cylinder extends or retracts, creating the force needed to raise or lower the trailer bed, tilt deck, or other hydraulic components.
Every hydraulic system depends on clean hydraulic fluid, properly sized components, and leak-free connections to operate safely and reliably.

HYDRAULIC PUMPS
The hydraulic pump is the heart of the hydraulic system. Powered by a 12-volt electric motor on most dump trailers, the pump generates hydraulic pressure that moves fluid from the reservoir to the hydraulic cylinder. Selecting the correct pump depends on the trailer's hydraulic system design, cylinder type, pressure requirements, and flow requirements.
Deer Valley Trailer carries replacement hydraulic power units and related components for many popular dump trailer and equipment trailer applications.
HYDRAULIC POWER UNITS
Most dump trailers use compact self-contained hydraulic power units that combine the electric motor, hydraulic pump, fluid reservoir, relief valve, and control manifold into a single assembly. These units are designed for dependable operation while simplifying installation and maintenance.
HYDRAULIC CYLINDERS
Hydraulic cylinders convert hydraulic pressure into the lifting force required to operate your trailer. Choosing the correct replacement cylinder requires matching the bore size, stroke length, mounting style, and operating pressure to your existing hydraulic system.
SINGLE-ACTING HYDRAULIC CYLINDERS
Single-acting cylinders use hydraulic pressure to extend the cylinder while gravity or the trailer's weight returns the cylinder to its retracted position. This design is commonly found on many dump trailers because it provides reliable lifting performance with a simple hydraulic system.
DOUBLE-ACTING HYDRAULIC CYLINDERS
Double-acting cylinders use hydraulic pressure for both extension and retraction, providing greater control over cylinder movement. They are commonly used on hydraulic tilt trailers, specialty equipment trailers, and applications where powered movement in both directions is required.
TELESCOPIC CYLINDERS
Many dump trailers use telescopic hydraulic cylinders to achieve significant lifting height while maintaining a compact retracted length. Multiple nested stages extend sequentially, allowing the trailer bed to reach a steep dumping angle for efficient unloading of gravel, dirt, debris, and other materials.

HYDRAULIC SYSTEM MAINTENANCE
Routine maintenance is one of the best ways to maximize the life of your hydraulic system. Regularly inspecting hydraulic hoses, fittings, cylinders, electrical connections, battery cables, and fluid levels helps identify potential problems before they become major repairs. Clean hydraulic fluid is essential for protecting pumps, valves, and cylinders from premature wear, while replacing damaged hoses or leaking seals promptly can help prevent more extensive hydraulic system damage.
DEER VALLEY TRAILER EXPERT TIP
One of the most common mistakes we see is replacing a hydraulic pump without determining why it failed. Low battery voltage, poor electrical connections, contaminated hydraulic fluid, damaged cylinders, leaking hoses, or sticking control valves can all place additional strain on the hydraulic system. Before replacing major components, inspect the complete hydraulic and electrical system to help identify the root cause of the problem. This approach often prevents repeat failures and helps ensure long-term reliability.
