Model Code Selection
The model code provides a detailed breakdown of product series, displacement, valve plate, input rotation, input shaft, mounting flange, main port location and type, special features, control options, and compensator settings.
Specifications and Performance
Specifications for various pump models include maximum geometric displacement and mounting flange specifications, as well as available shaft-end types.
Control Options
Control options include pressure and flow compensators with various settings, allowing customization based on application needs.
Operating Requirements and Recommendations
Guidelines for efficient pump operation include recommendations for installation and start-up procedures.
Typical Applications
M Series pumps are suitable for applications such as mining machinery, injection molding machines, metal forming machines, oil and gas equipment, conveyor lines, primary metals, and metal cutting equipment.
Features and Benefits
The pumps offer long life, quiet operation, low pressure ripple, reduced maintenance, and flexibility in machine design, promoting a leak-free system.
Performance Overview
The document provides detailed performance metrics for the Industrial Variable Displacement Piston Pumps, specifically the PVM020 model, including data on delivery, efficiency, input power, and torque at various operational speeds and conditions.
Specifications
The pump's performance is evaluated at different rotational speeds (1800, 1500, 1200, and 1000 r/min) and a constant temperature of 50°C (120°F) with an inlet pressure of 1.0 bar absolute (0 psi gauge).
Delivery and Efficiency
Graphs show delivery (effective flow) and efficiency (volumetric and overall) against outlet pressure, with efficiency percentages provided for each speed setting.
Input Power and Torque
Charts illustrate the relationship between input power (kW and hp) and torque (Nm and in.lb.) at full stroke and cutoff conditions.
Noise Levels
Noise level data is provided for different operational speeds, measured in decibels (dBA), with petroleum oil (10W) as the working fluid, compared to NFPA standards.
Case Flow vs. Outlet Pressure
Graphs show case flow rates against outlet pressure at full flow and cutoff conditions, providing insights into the pump's internal leakage and efficiency under varying pressures.
Key Observations
- Input torque and power increase with speed and pressure.
- Efficiency tends to decrease as outlet pressure increases.
- Noise levels are documented for various speeds, showing typical values for industrial settings.
Recommendations
For optimal performance, it is recommended to operate within the specified speed and pressure ranges. Regular monitoring of noise levels and efficiency can help in maintaining the pump's performance and longevity.

Eaton M Series pumps are open circuit, axial piston designs. A variety of control options allows the pumps to perform most efficiently in a specific application. Efficiency of the pump controls allows down-sizing of system cooling needs, saving up front cost in the machine. Alternatively, cooling capacity could be kept the same and the flow capability of the system increased, thus improving performance and customer satisfaction. The M Series also contains a strong proven rotating group allowing the pumps to handle pressures to 280 bar (4000 psi) continuous and 320 bar (4600 psi) intermittent...

Control Options Pressure Compensator Control – Code A The pump will provide a continuously modulated flow to meet changing load demands at a pre-adjusted compensator pressure. At pressures below the compensator setting, the pump will operate at maximum displacement. See model code on page 4 for compensator pressure ranges. Warning: The pressure compensator may be adjusted beyond the rated pressure of the pump. When adjusting the pressure limiter, install a 0-350 bar (0-5000 psi) gage in the outlet gage port and limit the pressure setting to the continuous rated pressure for the pump displacement...

Control Options Load Sensing and Pressure Compensator Control – Code B or C The pump will provide power matching of pump output to system load demand, maximizing efficiency and improving load metering characteristics of any directional control valve installed between the pump and the load. Load sensing ensures that the pump always provides only the amount of flow needed by the load. At the same time, the pump operating pressure adjusts to the actual load pressure plus a pressure differential required for the control action. When the system is not demanding power, the load sense control will operate...
