subject: Hydraulic Pumps Types And Operating Specifications [print this page] Hydraulic pumps source out their power from mechanical forces in order to pump fluid into the pump's own outlet. Like a motor they are capable of rotating and acting. It is very important to know about the operating specification of these pumps and to check into the features it possesses, in order use the best type of these pumps.
According to their type and operating specifications these hydraulic pumps are subcategorized. Depending upon the type, it can be an axial or radial piston, an internal or external gear or a vane. As far as the operating specifications are concerned, it not only involves operating speed, horsepower and temperature but also includes continuing and maximum operating pressures.
Now discuss some types of Hydraulic pumps
A hydraulic ram pump- Powered by hydropower a hydraulic ram pump functions as a hydraulic transformer that takes in water at one "hydraulic head" (pressure) and flow-rate, and outputs water at a higher hydraulic-head and lower flow-rate. To develop pressure that allows a portion of the input water that powers the pump to be lifted to a point higher than where the water originally started, these pumps utilizes the water hammer effect.
The hydraulic ram or hydraulic hand pump is sometimes used in remote areas, where there is both a source of low-head hydropower, and a need for pumping water to a destination higher in elevation than the source. The ram is often useful in such situation, since it doesnt need any outside source of power other than the kinetic energy of flowing water.
