A double-acting hydraulic pump (4-button, 6-quart reservoir) is a compact power unit used to control hydraulic cylinders in both directions—extension and retraction—with precision.
🔧 Key Components & Meaning
Double-acting (DBL ACTING): The pump sends hydraulic fluid to both sides of a cylinder, allowing it to extend and retract using powered force (not relying on gravity to return).
4-button control (4-BUTTON): A handheld or mounted control panel with four switches/buttons, typically used for:
Extend (raise)
Retract (lower)
Possibly control multiple cylinders or functions (e.g., up/down for two circuits)
6-quart reservoir (6QT): The unit holds about 6 quarts (~5.7 liters) of hydraulic fluid, which supplies the system.
⚙️ How It Works
Motor activates pump: An electric motor drives a hydraulic pump that pressurizes the fluid.
Directional control valve: When you press a button, a valve directs fluid:
To one side of the cylinder → extends (pushes out)
To the opposite side → retracts (pulls back)
Fluid return cycle: Fluid from the opposite side of the cylinder returns to the reservoir
