Eaton Vickers PVB90 Hydraulic Pump is a pump that generates high displacement and high variable flow and is intended for heavy duty open circuit hydraulic systems. The inline axial piston design of the pump gives a geometric displacement of 197.50 cm³/rev and allows working with the maximum outlet pressure of 210 bar.
PVB90 pump automatically regulates its displacement according to the needs of the system. At the high load working cycle, the pump can generate the necessary flow rate to produce a high actuator force. In case when the system does not need much hydraulic power, the pump will be able to decrease its output.
This pumps can be used for large presses, formers, material handling machines, heavy production lines and central hydraulic power units. PVB90 pump can work with pressure compensated, load sensing and other special control schemes. But all of them depend on the configuration chosen.
Appropriate inlet conditions are necessary to ensure the smooth operation of high flow pumps. The suction pipe must not be too small to allow adequate oil to enter the pump because inadequate oil may lead to cavitation, noise and internal damages. It is also advisable for operators to keep the hydraulic fluid clean and with correct viscosity and filtering.
The following issues: reduced machine power, slow actuator response, unstable pressure are indications of pump wear. Some additional signs include vibrations, high hydraulic oil temperature and leakage at shaft and control section of the pump. It is recommended to check the entire circuit in order to rule out valves, filters and inlet problems because their symptoms resemble those of pumps.
Rexton Hydraulic is a sales and service provider of Eaton Vickers PVB90 hydraulic pumps for heavy industrial applications. Our engineers examine the whole pump codes, working conditions and the install it with recommendations regarding replacement or repair of pumps. We also perform inspection, component assessment and rebuilding services.
