There are typically three types of hydraulic pump constructions found in mobile hydraulic applications. These include gear, piston, and vane; however, there are also clutch pumps, dump pumps, and pumps for refuse vehicles such as dry valve pumps and Muncie Power Products’ Live PakTM. The hydraulic pump is the component of the hydraulic system that…
This low profile hydraulic jack is only 2 inches high, but the stroke is up to 1 inch. Compared with ordinary jacks, multi-section jacks can be used in a narrower and lower space, effectively increasing the stroke of the jack within the height of the body, so that the weight can be raised higher and…
What are hydraulic gear pumps used for?
A hydraulic pump is a mechanical device that converts mechanical power into hydraulic energy. It generates flow with enough power to overcome pressure induced by the load. A hydraulic pump performs two functions when it operates. Firstly, its mechanical action creates a vacuum at the pump inlet, subsequently allowing atmospheric pressure to force liquid from…
In a condition-based maintenance environment, the decision to change-out a hydraulic pump or motor is usually based on either remaining bearing life or deteriorating efficiency, whichever occurs first. However, there are also certain situations where it is helpful, or even necessary, to quantify the pump or motor’s actual efficiency and compare it to the component’s…
