Product Overview
▔▔The Yuken AR series variable displacement piston pump represents a milestone in modern hydraulic engineering. Developed by Yuken, a global leader in fluid dynamics, this series is engineered specifically to deliver high performance in a compact, lightweight package. It strikes an ideal balance between high operating efficiency and low acoustic emissions, making it an excellent upgrade for traditional industrial systems.
Key Advantages
▔▔-
Exceptional Efficiency: Volumetric efficiency exceeds 95% at standard operational thresholds, minimizing power losses and saving electricity.
Ultra-Low Noise Levels: Advanced swash-plate geometry reduces internal vibration, keeping noise below 55 dB(A) under nominal loads for a quieter workshop.
Lightweight Aluminum Housing: Utilizes high-tensile aluminum alloy construction to reduce overall machinery weight without compromising pressure resistance.
Cost-Effective Maintenance: A highly modular internal architecture allows for quick interchangeability of wear parts, significantly decreasing operational downtime.

FAQ
▔▔Q1: What is the main operational difference between the AR16 and AR22 models?
A: The primary difference lies in their internal geometric displacement. The AR16 delivers 15.8 cm³ of fluid per shaft revolution, whereas the AR22 delivers 22.2 cm³ per revolution. Both models share the exact same external physical dimensions and mounting footprint, allowing factories to scale up system flow without modifying physical machine mounts.
Q2: Can the Yuken AR series pump operate with water-glycol or synthetic fire-resistant fluids?
A: The standard AR series is optimized for petroleum-based mineral hydraulic oils. If your application mandates fire-resistant fluids like water-glycols or phosphate esters, special internal fluorocarbon seals (Vitons) must be specified during ordering to prevent chemical degradation of the internal components.
