GUM

The gum content tester helps to prevent induction-system difficulties by measuring the unevaporated residue of fuel that may lead to deposits and sticking intake valves. Featuring a multi-function head for simultaneous positioning of all 5 sample tubes increases accuracy and safety. GUM is suitable for aircraft fuels, motor gasoline and other volatile distillates.

Options: GUM for tests with air or steam supply GUM for tests with air supply only

Standard methods:
ASTM D381, ISO 6246, EN6246, JIS K 2261, DIN 51784, FTM 791-3302, IP 131, IP 540

Application range:
Up to +280 °C (air & steam supply)
Up to +246 °C (air supply)

Sample volume:
50 mL per tube

Benefits of GUM at Jet fuel

This method is used to determine the existent gum content of aviation fuels, the gum content of motor gasoline or other volatile distillates. High gum content can cause induction system deposits and sticking of valves,while a low gum content will ensure the proper function of the induction system or the carburetor. In case of aviation turbine fuels, a high gum content is indicative of contamination by higher boiling oils, caused by poor handling of the downstream process in the refinery.
