Foam Tester

The foam tester allows the determination of the foaming characteristics of lubricating oils at specific temperatures by empirically rating the foaming tendency and the foam stability. Especially in high-speed gearing and high-volume pumping systems, the tendency of oils to foam can lead to inadequate lubrication or cavitation, which may result in mechanical failure. For a more convenient workflow the foam tester comprises two individually maintained baths.

Standard methods:

Application range:
24 °C to 150 °C

Test places:
1 to 8

Sequence IV equipment

Benefits of Foam Tester at Terminal

Foaming can be a problem in gears and pumps, leading to mechanical failure. The foam tester determines the foaming characteristics of lubrication oils. The sample is blown with air at 24 °C and the foam is allowed to settle for 10 minutes. The volume of foam is measured before and after. The test is repeated at 93.5 °C.  This is a required test method to certify turbine oils and is used for evaluation purposes.
