– Designed to SH/T0087 Standard for Accurate Evaluation of Coolant-Induced Cavitation Corrosion on Aluminum Pumps
During high-speed circulation, engine coolant can cause cavitation corrosion on aluminum water pump impellers, directly affecting cooling system life. The DFYF-931 Cavitation Corrosion Tester is designed and manufactured in strict accordance with industry standard SH/T0087, specifically for evaluating the cavitation corrosion tendency of engine coolants on aluminum pumps. It provides a critical testing tool for coolant formulation optimization and quality acceptance.

Key Features
◆ Standard Test Pump
Equipped with a GM (General Motors) standard test pump, fully compliant with ASTM requirements, ensuring test results are comparable to international methods.
◆ Precision Reservoir Design
The reservoir features a pressure sensor and a thermometer port for temperature correction, improving test realism and repeatability.
◆ Full Stainless Steel Circulation Piping
All circulation lines are made of stainless steel – corrosion-resistant, contaminant-free, and reliable for long-term use.
◆ One-Key Automatic Sampling
After preparing the sample, simply press one button for automatic sampling. Easy operation reduces human error.
◆ Fully Automatic Pressure Control
Integrated pressure maintaining and relief system controls the pressure within 100–106 kPa (factory preset, no user adjustment needed). When pressure drops below 100 kPa, the system automatically pressurizes to 100 kPa; when it exceeds 106 kPa, the relief valve activates until pressure falls below 106 kPa. No manual intervention required – precise pressure control ensures stable instrument performance.
◆ Microprocessor Temperature Controller
Digital display with Pt100 sensor, temperature control accuracy of ±1°C, ensuring stable testing under the set temperature conditions.
◆ Digital Timer with Auto Shut-off
Built-in digital timer accurately records cumulative test time. When the test reaches 100 hours, the system automatically cuts off power for safe and unattended operation.
Applications
The DFYF-931 is suitable for engine coolant manufacturers, quality inspection agencies, automotive parts laboratories, and research institutes. It is used to evaluate the cavitation corrosion degree of coolants on aluminum pump impellers under high-temperature, negative-pressure circulation conditions – an ideal tool for cavitation resistance R&D and quality control of coolants.
