Eaton Vickers PVM057 Hydraulic Pump is designed for open hydraulic circuits, providing reliable pressure and adjustable flow rates. The axial pistons' geometric displacement is 57.4 cm³ per revolution, providing a realistic range of output suitable for demanding mobile machines and industry equipment. Due to the capability of varying the displacement of the pump, the hydraulic flow rate can be adjusted according to the machine needs rather than delivering maximum flow continuously.
The pump provides a nominal pressure of 315 bar and maximum peak pressure of 350 bar. Maximum operating speed of the pump is 1,800 rpm, where maximum flow is 102 liters per minute at 1,800 rpm. The weight of the pump is 36 kg. These figures are intended to be applied as selection criteria since they are affected by hydraulic fluid viscosity, oil temperature, inlet pressure, system load, and control configuration chosen.
Pressure compensation and load sensing are two control variants provided by the PVM series. Pressure-compensation can decrease the displacement of the pump after reaching the specified pressure, and a load-sensing system can control the displacement according to the working requirement of the hydraulic circuit. In this way, unnecessary generation of flow is prevented because the machine does not require more hydraulic power than necessary. Thus, more controlled operation, energy saving and reduction in heat generation may be achieved compared to an undersized or overloaded pump.
Each PVM057 pump may vary in terms of mounting flange, drive shaft, hydraulic ports, rotation direction, control system and through-drive configuration. Therefore, the complete selection of a pump cannot be made by its model number or its external appearance only PVM057 pumps. It is important to note that the pump's full name (model code) includes all information about the pump. The full name code of the pump written on its nameplate, as well as.
