DERC Rupture Disc Holder

Safety device for high pressure pump systems

The DERC Rupture Disc Holder is specially designed for the waterjetting industry as a safety device for high pressure units and systems. When the pressure gets higher than the rupture disc permits, the rupture disc will break out, which results in an immediate system pressure drop. Therefore the installation can never exceed the maximum pressure of the mounted bursting disc. 

Rupture disc/bursting disc

The DERC Rupture Disc Holder holds a rupture disc, also known as a bursting disc or burst disc. When the system pressure exceeds the maximum pressure of the rupture disc, it will break the rupture disc. As a result the water can now drain through the drain holes at the top of the Rupture Disc Holder. A protective hood is installed over the drain holes is, which prevents the water from spraying around uncontrolled.

The male inlet connection can be inserted directly into a valve manifold or fitting. The connections are 1/2" NPT, 13/16"-16 UNF (9/16"MP), 1 1/8"-12 UNF (9/16" HP).

The DERC Rupture Disc Holder should always be sealed with seal wire and associated bursting seal after placing the rupture disc. In this way, the safety is ensured and it is always clear what type of bursting disc is mounted in the holder.
