Applications

It is a general purpose mechanical seal with a wide range of applications. It is designed to operate with cold and hot water, oils, fuels, not very aggressive chemicals and other liquids containing small amounts of abrasives.

The A3 seal with a central spring is dependent on the direction of the shaft rotation. Looking at the slide ring face, a right handed shaft rotation needs a right handed spring (A3R) and left handed shaft rotation needs a left handed spring (A3L).
