The Hydraulic Multi-Pass Test Bench is a precision filtration testing system designed to evaluate hydraulic filters, oil filters, fuel filters, and other fluid filtration materials. By continuously introducing test contaminants and using online particle counting, the system dynamically measures filtration efficiency, contaminant holding capacity, and pressure drop characteristics under realistic operating conditions. This provides accurate, repeatable data for filter performance analysis, R&D, and quality control.
Application
(1) Hydraulic Filter Testing – Evaluate full-flow hydraulic filters for industrial machinery, construction equipment, and mobile hydraulics.
(2) Engine Oil Filter Assessment – Test efficiency, dirt-holding capacity, and pressure drop of engine oil filters in automotive and heavy-duty applications.
(3) Fuel Filter Evaluation – Assess diesel, gasoline, and alternative fuel filters for filtration precision and contaminant retention.
(4) Filtration Media Development – R&D labs can test new hydraulic or oil filter media formulations.
(5) Industrial Quality Control – Monitor and verify filter performance during manufacturing or incoming inspection.
(6) Training & Demonstration – Educational institutions or technical centers can demonstrate filtration principles and test methods.
Standards
(1) GB/T 18853 — Hydraulic filters — Multi-pass method for evaluating filtration performance (China).
(2) ISO 16889 — Hydraulic filters — Multi-pass method for evaluating filtration performance (International).
(3) ISO 4548-12 — Full-flow lubricating oil filters for internal combustion engines, filtration efficiency and contaminant capacity.
(4) ISO/DIS 19438 — Diesel and gasoline fuel filters, filtration efficiency and contaminant capacity by particle counting.
(5) SAE J1858 / ASTM F23 — Supplementary international guidance for multi-pass filter testing.
Features
(1) Fully Automated Control – PLC-based system for automatic operation, monitoring, and data logging.
(2) High Measurement Accuracy – Integrated KZD-3A online particle counter with 32 channels for precise upstream and downstream readings.
(3) Comprehensive Testing – Measures filtration efficiency, contaminant holding capacity, and flow-pressure drop in a single platform.
(4) Precise Thermal Management – Automatic heating and silicone-rubber electric heating with refrigeration cooling for stable oil temperatures.
(5) Robust Construction – Stainless steel pipelines, aluminum frame, and high-quality components ensure durability and contamination-free operation.
(6) Modular Fixture Design – Adaptable for various filter elements, including spin-on and media panels.
(7) Real-Time Data Output – Flow rates, pressure drop, and particle counts displayed and logged continuously.
