Hydraulic pumps are devices that convert a mechanical force into hydraulic energy (fluid flow). You will find hydraulic pumps on all sorts of hydraulic systems where movement of fluid is necessary. Some common examples include oil, water and coolant pumps that move the fluid from a reservoir and circulate it through the system.
Hydraulic fluid flow can be used to create mechanical movement (typically on a geared shaft) through the use of a hydraulic motor. While many configurations of hydraulic motors exist, the basic principle is the same: flowing fluid applies a force to a gear (or gears) and creates a rotational movement on a gear as the fluid passes from the inlet port to the outlet port.
While the pump is the heart of a hydraulic system, it wouldn’t function without the right hydraulic valves. These components come in various types and configurations and are used to adjust the pressure, flow and direction of the fluid as it flows through your system. Depending on the complexity and size of your hydraulic system, your number of valves will vary. Proper maintenance and service is key to ensuring a healthy and reliable hydraulic system.
Depending on the type of hydraulic system you have and your need for consistent and stable operation, a hydraulic accumulator may be necessary. An industrial hydraulic accumulator is filled with energy (pressurized fluid) during normal system operation that it stores and releases when the system pressure falls below a predetermined level. Once the system is back up to the pressure, the accumulator is automatically charged again, ready for the next drop in pressure.
