Product catalog summary

Overview of PVM Open Circuit Piston Pumps
Eaton's PVM series open circuit piston pumps have been enhanced to offer increased versatility and performance. Key improvements include an upgraded nominal pressure rating from 280 to 315 bar for standard displacements, a new 'Power Control' option with a hydro-mechanical torque limiter, and performance data for low shaft speed operations in variable speed applications.

Specifications and Features

Pressure Ratings: The PVM series has been tested for improved pressure ratings, with models such as PVM018, PVM045, PVM057, PVM074, PVM098, and PVM131 now supporting a nominal pressure of 315 bar and a peak pressure of 350 bar.
Power Control: This feature limits the maximum torque output by reducing displacement as pressure increases, preventing the stalling of the prime mover/motor and allowing larger pumps to operate with the same motor size.
Variable Speed Performance: The PVM pumps are optimized for quiet operation and low inertia, making them suitable for both open and closed loop motion control modes. They support a wide speed range, with standard speed versions optimized for low sound at 1800 RPM and high-speed versions reaching up to 2800 RPM depending on displacement.

Applications
The enhanced PVM pumps are suitable for a variety of applications, including discrete manufacturing (presses, machine tools), processing industries (primary metal, food, wood), oil/gas/marine sectors, alternate energy (wind turbines), and general industrial uses (hydraulic power units).

Model Code and Options
The document provides a detailed model code for the PVM series, outlining options for displacement, valve plate, input rotation, input shaft, mounting flange, main port location and type, special features, control options, and compensator settings. This allows for customization to meet specific application needs.

The latest addition to control options* for PVM, the Power control** limits the maximum torque output by the piston pump by reducing the displacement as pressure increases hence limiting the power rating at a given speed. As pressure increases the pump displacement is reduced such that the set torque value is not exceeded. The addition of this Power control option provides the option of operating of larger size pump with same size motor. It also prevents the stalling of prime mover/motor by ensuring the set torque is not exceeded. * Available control options are listed in the model code on the...
