Message:There are several types of hydraulic pumps. While most of them fall into the fixed displacement category, some can be categorized under adjustable displacement as well. Screw pump is a type of hydraulic pump that looks sort of a double Archimedes spiral, only closed. Having two screws in one body, the screw pumps are used for high flows and relatively low pressure. Usually seen on board ships, this pump has a constant pressure hydraulic system for the control of ball valves, and also for the steering gear and help drive systems. Although the efficiency is not that high, this type of hydraulic pump has the advantage of low sound levels. Anotherhydraulic pumps type would be Gerotor pumps. This very special pump has more efficiency as well as the sound level, knowing that this is only a medium pressure pump. Gear pumps are on the simple side, an economic pump that is used in simple hydraulic systems. However, the efficiency of such is not very good, especially at higher pressures. Vane pumps would be another type of hydraulic pumps where it has a higher efficiency rate as compared to gear pumps. In general, vane pumps can be used for mid pressures for up to 180 bars. There is also the axial piston pump, which has the best efficiency level among all the other pumps. These pumps can work with a pressure of up to 350 bars. Radial piston pumps, on the other hand, are used specifically for high pressure and relatively small flows.
