Overview

Low-Noise, Efficient and Reliable Hydraulic Power System

The Moog Silent Hydraulic Power Unit (HPU) is a reliable and efficient hydraulic power system that provides stable hydraulic power to machinery and equipment. The Silent HPU series covers a wide range of flow needs, from 100 l/min output to the maximum of 600 l/min. The Silent HPU is design based on a modular construction that allows for product assembly to be configured according to user requirements and with high flexibility when expanding output flow is required.

The Silent HPU features a robust and contamination-resistant designed radial piston pump that delivers high-pressure output while maintaining high reliability and long service life.

The rapid response and high volumetric efficiency of the radial piston pump promote overall efficient operation of the HPU and help save energy. The optimized design of the internal structure, achieved by increasing the piston count with smaller piston diameters, reduces flow and pressure pulsations on the high-pressure side, resulting in decreased noise emissions.

Features

  • Control cabinet (with the control panel) can be positioned either left or right-hand sides to fit space constraints and equipment layout
  • In addition to local operation, the Silent HPU can also be equipped with remote control functions to flexibly meet operational needs
  • The Silent HPU offers a Flow-on-Demand feature that intelligently controls the flow output for better energy savings
  • Multiple Silent HPU can be connected to form a hydraulically shared HPU as a single system of higher flow rates
  • Motor and pump assembly immersed in the oil tank to reduce the noise generated during operation
  • The pump assembly rack and oil tank are installed in the structure of the Silent HPU by means of mechanical isolation connection to maintain the overall noise in a low level

1) The output flow is calculated based on a 50 Hz power supply.

2) The measurement of the noise level [dB(A)] vary depending on the environment in which the device is located, and the noise level is measured in a free space environment.
