One question that comes up quite frequently, in regards to those businesses and individuals that keep an inventory of hydraulic cylinders parts on hand

If you operate hydraulic machinery in cold weather or cold environments, there are changes in how hydraulic system components function in colder temperatures.

BCC Research published a “Global Markets for Hydraulic Pumps” report back in 2014 that examined the future economic impacts and growth for this industry on a global scale.

Selecting the right hydraulic oil for your hydraulic system requires taking into account the type of oil and the viscosity. The proper oil specifications are also directly related to the type of pump used in the system.

Think about this for a moment: A hydraulic system is only as good as the cleanliness of the hydraulic fluid used within the system. If you do not take steps to properly filter the fluid, you will spread contaminants throughout the entire system.

Pumps are key components of a hydraulic system, generating hydrostatic energy by conveying oil (or another suitable fluid) through machinery in a precisely modulated manner. As hydraulic machinery varies in size, complexity, and functionality, the pumps within these systems vary as well to accommodate the particular demands of the application.

Hydraulic systems are typically operated using one of two different types of pumps: hydraulic gear pumps and piston pumps. There are key differences between the two types of pumps in how they operate, which is essential in choosing the right pumps for your needs.

The efficiency of hydraulic pumps and motors helps you determine when it is time to replace the pump or motor or both. A decline in pump efficiency is sometimes easy to notice, especially if the cycle times are becoming longer or maximum pressure levels are not being reached.

There are several different factors that can affect the life expectancy of hydraulic pumps. A good general rule of thumb is to begin by reviewing the expected number of operating hours the pump will run before it fails.

Before you bleed out the air in your steel tubes and other hydraulic system components, it is important to know whether there is air in your system. If you notice erratic operation with a drop in hydraulic pressure, there is probably air getting into the system somewhere, such as through a cracked hose.
