How to Correctly Determine Hydraulic Pump Condition Using Volumetric Efficiency

Rexroth A2VSL1000 hydraulic pumpThe hydraulic pump is usually the hardest working component of a hydraulic system. And as the pump wears in service, internal leakage increases and therefore the percentage of output flow available to do useful work (volumetric efficiency) decreases. If volumetric efficiency falls below a level considered acceptable for the application, the pump will need to be changed-out. In a condition-based … Read more

5 Things You Must Tell Your Hydraulic Equipment Supplier (OR 5 questions to make sure you ask your customer if you’re a hydraulic equipment designer!)

big question markWhen sourcing a piece of hydraulic equipment, there are five things about the environment the machine will operate in, that you should always disclose to the equipment supplier or designer-even if they don’t ask. Especially if they don’t ask:

1. Minimum and maximum ambient temperature. This information is necessary to determine the correct hydraulic fluid type, viscosity grade and … Read more
