Description

Parameter Specification for YUKEN Variable Displacement Piston Pump A56-LR01AS-60

This document provides detailed parameter specifications of the YUKEN A56-LR01AS-60 variable displacement piston pump, including model interpretation and key technical parameters, to facilitate installation, operation and maintenance reference.

1. Model Explanation

Model: A56-LR01AS-60
  • A56: Series identifier, YUKEN variable displacement piston pump (medium-to-large displacement, suitable for medium-flow, high-pressure industrial hydraulic systems, larger displacement than AR16 series)
  • LR: Mounting and connection type, thread-mounted with standard connection specifications (easy to install and disassemble, suitable for flexible installation scenarios in medium-flow hydraulic systems)
  • 01AS: Control type, constant pressure control with pressure compensation and signal feedback (automatic flow adjustment according to system pressure, with signal feedback function for intelligent system control, more advanced than conventional 01C type)
  • 60: Configuration code, special seal and large-size port design, adapted to harsh industrial working conditions, matching petroleum-based hydraulic oil and compatible with partial flame-retardant oils
