Eaton Vickers 25V Hydraulic Pump provides constant fixed-displacement flow for open circuit industrial and mobile hydraulic applications. The balanced-vane pump is equipped with replaceable cartridge kits offering displacement capacities of about 33 to 67 cm³ per revolution.
This pump moves a fixed amount of hydraulic oil per shaft revolution. Thus, the pump speed will provide the flow capacity, and the connected circuit will control its use to accomplish the intended work. The simple and reliable operating principle enables the pump to be used in equipment where stable hydraulic flow is needed.
Some 25V pump models can withstand up to 172 bar pressure. However, it is important to note that the permitted pressure depends on the cartridge size, rotation speed, hydraulic fluid type, temperature and cycle load of the application. The users have to find out the rating for the whole model number rather than using the same pressure for all 25V pumps.
The replaceable cartridge incorporates the main components of the pump: rotor, vanes, cam ring and pressure plates. Sometimes, technicians can disassemble the unit and do repairs without the need to replace the entire pump. The balanced design of the pump is directed to hydraulic forces in such a way as to minimize radial loads on the drive shaft and bearings. Such an internal configuration allows the pump to operate smoothly and efficiently under certain fluid conditions and speed.
Eaton Vickers 25V pump models can be used in such applications as hydraulic power units, machine tools, presses, material handling equipment and manufacturing machinery. Different 25V pump models might have various shaft, mounting flange, port orientation, cartridge capacity and rotation direction. Therefore, proper identification becomes crucial for replacement purposes.
Possible signs of pump wear include low pressure, decreased flow, strange noise, overheating, external leakage and slow machine action. Also, similar problems can arise because of limited inlet flow, contaminated oil, improper viscosity and damaged vanes or cam surfaces.
