Bubble Test
 |
The bubble test is a frequently used visual test method. The surface must be visible for this method. After creating a pressure difference at the test specimen a foam-creating test liquid (indicator) is coated onto the low-pressure side of the test specimen. A homogenous thin and well-coated layer is required for the detection of small leakages. At the location of a leakage bubbling takes place due to gas emanation. |

The vacuum pump EV 20 N is suitable for leak tests at
- Pipes
- Tanks
- Sheet construction
Butt joints, hollow seams, corner joints as well as fused nozzles can be tested. Especially for tests of pipe constructions this method has proven to be highly reliable.
For enhancement of the operation safety the pump is protected by water seperator, flotation valve as well as back-pressure valve and filters.
