Fuel-Water Separator Test Stand
The Advanced Fuel-Water Separator Test Stand is designed to evaluate the water separation efficiency of diesel fuel filters and fuel-water separators under controlled laboratory conditions. The system integrates fuel circulation, water injection, pressure and temperature control, and automated water content analysis to assess separator performance with high repeatability.
The test stand supports flow rates from 1 to 25 L/min and provides automated injection, titration, data acquisition, and report generation. Its programmable control system enables unattended testing according to configured test procedures, making it suitable for fuel filter manufacturers, automotive component laboratories, and diesel fuel system research and development.
