Eaton Vickers PVB20 Hydraulic Pump

Eaton Vickers PVB20 Hydraulic Pump is constructed in variable-displacement axial piston design used in various applications. The industrial hydraulic systems require the pump that can react quickly and efficiently to load variations, and this pump fulffils the same. Geometric displacement of this hydraulic pump is 42.80 cm3/rev and maximum outlet pressure is up to 210 bar. The PVB20 is applicable to medium flow open circuit installations.

The Eaton Vickers PVB20 Hydraulic Pump alters its displacement depending on hydraulic demands. When less flow is needed, the pump reduces its output instead of pumping the extra oil continuously. During the active working cycle, the pump increases its flow rate in order to drive the actuators and create the pressure. It helps to control power usage, hydraulic oil temperature and unnecessary wear.

The PVB20 is applicable to the industrial press, machine tools, injection-molding equipment, hydraulic power packs and material handling equipment. The various control options allow this pump to be used in different applications. There are several control options such as pressure compensation, load sensing and other specialized control designs. Some selected pumps may provide the option of through-drive which allows to connect another hydraulic pump to the same shaft.

Routine maintenance is essential in maintaining efficient performance of the pump. Proper care of the hydraulic oil, correct viscosity and filtration are key factors. In addition, the operators should also examine the inlet line for restriction, improper sizing and air ingestion. These situations will lead to the development of cavitations, abnormal sounds and damage on the rotating components. Oil temperature and pressure settings may be examined to minimize premature wear.

The common problems associated with pumps include instability in pressure, sluggish machine operation, low flow rate and overheating. Other possible problem includes leakage around the shaft seal and control housing. However, one should examine filters, valves and system settings prior to making the diagnosis.
