Type 270P
The type 270 P is a stationary single-cartridge seal with an additional safety seal. The DEPAC safety seal guarantees a high degree of process safety through targeted leakage if the mechanical seal fails. The advantage: The emergency seal ensures that operation can continue until the next planned maintenance – thus reducing the cost risk of a production standstill.
The type 270 P is supplied as standard in the O-ring design version.
