Busch VM 100

Premium vacuum pump lubricant

Basic Identifiers

5245 vacuum mineral DVC 100


Busch VM100 is characterized by low vapour pressure, which makes the product suitable for working pressures of approx 100 mbar to approx 10- 2 mbar. The product has a high viscosity index, because of which, viscosity changes are relatively small when the temperature changes. Because of the good oxidation stability, Busch VM100 is suitable for use at high temperatures. Because of this, Busch VM100 had a longer life span than conventional lubricants. Busch VM100 has an excellent water separating capacity. Water in the oil, as a result of forming of condensation, can easily be drained. Because of this, corrosion is prevented and the oil maintains its lubricating properties.

ASTM D341 Viscosity Calculator

You may calculate the viscosity of the oil at various temperatures based on ASTM D341. This uses the two sets of calibration data that we already have in order to calculate the viscosity at any temperature. You may input multiple temperatures at once, seperated by comma.
