Use of the magnetic fluid seal technology in water is much more difficult technological problem in comparisonto gas or vacuum environment. Some seals constructed up to time been are designed as hybrid, two stagesealing structures with shields or mechanical seals used as protection measures to the magnetic fluid seal.Anyway, there is always problem with immediate contact between magnetic fluid and the environmentalliquid. In the paper are presented results of experiments carried out with one stage rotating magnetic fluidseal operating in immediate contact with utility water. The special test procedures have been elaboratedand practically used, with the aim to define main characteristics of magnetic fluid seals and to simplifyexperiments. These characteristics were: critical pressure, critical motion velocity and working life of theseal. Four grades of commercial, silicon based magnetic fluids of hydrophobic properties were tested ina single stage sealing system. The results of tests are presented in the form of tables and diagrams. It isconcluded that hydrophobic commercial magnetic fluids could be efficiently used in rotating shaft sealshowever in a limited range of motion velocity
