HYDRAULIC SYSTEMS: OPEN VS. CLOSED

Open vs. closed center hydraulic systems can be complex to understand. So let us explain the main differences between the two systems and the pros/cons of application use.  

Open Center Systems

In open center hydraulic systems oil flows through entire system continuously . A solenoid directs flow in the component to either operate the component (ex.- compressor or crane), or to bypass the component without operating it.

Closed Center Systems

In closed center hydraulic system’s the main pump is pressure compensated, which means that the flow is directed to components only when needed. When a component is not in use, the system pressure flow does not flow through the component.

What is the Best Option?

Open Center

– Pro: Easier to install – no load sense line

– Pro: Less expensive; smaller gear pump

– Con: Flow is constantly flowing at high pressure – creating heat

Closed Center

– Pro: Fuel savings – less HP required as you are not providing constant system pressure

– Pro: Less heat generated from constant flow

– Con: Expensive; larger pump required for operation
