DEPAC Stationary Parts - Extremely Versatile!

 A mechanical seal consists of several components: the rotating part, the stationary part and the gland. On the spare parts market the user will find diverse glands of different designs and dimensions for his equipment.
DEPAC offers a large selection of stationaries as an alternative to the spare parts traditionally stocked by the user. Selecting the optimum mechanical seal entails choosing the correct stationary part.
Alternatively the user can combine his selection of the optimum stationary part with a new matching gland or adapter (see pages 21 - 23).
