HYDRAULIC HAND PUMPS – GET THE LOW DOWN ON HIGH PRESSURE
Hydraulic hand pumps are mechanical devices used to generate hydraulic pressure by manual operation. They are commonly used in various applications where a relatively small amount of hydraulic force or pressure needs to be generated, such as in hydraulic jacks, presses, clamps, cylinders, and other hydraulic systems. These pumps are often employed in situations where electricity or other power sources are not readily available or practical.
The basic working principle of a hydraulic hand pump involves a handle or lever that is manually operated by the user. As the user applies force to the handle, it activates a piston or plunger inside the pump’s cylinder. This action creates a pressure difference, causing hydraulic fluid (usually oil) to be drawn into the pump from a reservoir or an external source. Subsequent strokes of the handle increase the pressure further, and this pressurized hydraulic fluid can then be directed to various hydraulic components through hoses or pipelines.
Hydraulic hand pumps are available in different designs and configurations, including single-acting and double-acting pumps. Single-acting pumps generate pressure in one direction, typically for extending a hydraulic cylinder. Double-acting pumps generate pressure in both directions, allowing for both extension and retraction of a hydraulic cylinder.
These pumps are valued for their simplicity, reliability, and ease of use, making them suitable for various industries such as automotive repair, construction, manufacturing, and maintenance. They are often used in situations where precise control of hydraulic force is required, and where portability and manual operation are advantages.
