Eaton Vickers PVM074 Hydraulic Pump features increased flow capability for use in high-demand open hydraulic circuits. It is an adjustable-displacement axial piston pump with the geometric displacement of 73.7 cm³ per revolution. With appropriate control equipment, it can vary its output depending on the hydraulic system needs. As such, it is designed for machinery operation based on varying pressures and flow rates within a regular work cycle.
According to the performance data, the nominal operating pressure is up to 315 bar, while the peak operating pressure is up to 350 bar. The PVM074 can run at a maximum speed of 1,800 rpm, and at that speed, it delivers about 127 liters per minute of maximum flow rate. The weight of the pump is approximately 45 kg. This information allows making an initial selection; however, the output will depend on hydraulic oil viscosity, temperature, inlet pressure, etc.
Pump can work with controls based on pressure compensation, load sensing and others depending on configuration. Pressure compensator will regulate displacement of pump after reaching the desired pressure by hydraulic system. At the same time, the load sensing control will depend on pressure and flow demands of working circuit. This set of control possibilities is going to allow the pump to provide the required output without generating unnecessary flow.
Eaton Vickers PVM074 Hydraulic Pump can be used for construction machinery, material handling equipment, industrial presses, processing machines, and hydraulic power units. With its flow and pressure characteristics it can be used with equipment which operates large cylinders or hydraulic motors. However, it is necessary to determine the whole system demands before using the pump. The oversized or incorrectly controlled pump will generate heat, consume additional energy and cause stresses in hydraulic equipment.
The model code will define the type of control, shaft, mounting flange, port arrangement, rotation direction and possibility of through drive of pump. Thus, two PVM074 pumps can have the same external look but have different installation requirements. Technicians should check inlet conditions, filters, case-drain flow and system pressure before deciding on repair or replacement.
