Type 196
The DEPAC type 196 is a stationary, balanced, single-component seal that was specially developed for installation spaces according to DIN 24960 / EN12756. The stationary design guarantees the best possible running smoothness and entirely rules out scoring of the shaft. The balancing results in lower face friction and thus less wear, which is reflected by an optimisation of the service life.
DEPAC also offers these mechanical seals in larger sizes than the standard sizes indicated in the standard. The mechanical seal can be combined with popular retainers, glands and adapter parts.
