Product Overview

▔▔

The Yuken variable displacement piston pump series (primarily focusing on the standard AR16 and AR22 frame designs) offers an ideal blend of compact geometry, high efficiency, and affordability. Specifically designed for low-to-medium pressure systems, it delivers excellent performance in applications requiring adjustable operational thresholds between 290 PSI (20 bar) and 2320 PSI (160 bar).

Key Advantages

▔▔

Precise Pressure Adjustability: The on-board compensator allows operators to easily dial in pressures anywhere from 290 to 2320 PSI.
Lightweight Aluminum Casing: Built with a specialized high-tensile aluminum alloy body that significantly reduces system weight and simplifies installation.
Superior Power Conservation: Rapid swashplate response ensures that the pump sheds flow output when system pressure limits are met, cutting electric utility costs.
Low Vibration & Quiet Design: Optimized internal port tracking limits fluid ripple, preserving a quieter manufacturing workshop floor.

FAQ

▔▔

Q1: How do I manually adjust the output pressure on this Yuken pump? A: There is an adjustment screw with a locknut located directly on the pump's pressure compensator block. Loosening the locknut and turning the screw clockwise increases the pressure cutoff limit, while turning it counter-clockwise lowers it within the 290 to 2320 PSI range.

Q2: What happens if my system pressure drops completely below 290 PSI? A: The internal control piston requires a baseline of 290 PSI to reliably stroke and destroke the swashplate. If the system pressure falls below this floor, the pump defaults to its maximum displacement (full flow) and its pressure control response may become unstable.
