|What Does a Hydraulic Filter Do? |
Some experts estimate that up to 75 percent of hydraulic power-fluid failures are the result of fluid contamination, notes Mobile Hydraulic Tips. Hydraulic filters protect hydraulic fluid and hydraulic equipment components from debris, rust and other particulate matter. Here are more details about hHow Does a Hydraulic Pump Work? Pumps are devices used to move liquids like water and fuel. Hydraulic pumps use liquid to convert mechanical energy into pressure and flow. Here's a brief look at how hydraulic pumps work.
