CEJN introduces coupling for construction and demolition industries

CEJN has introduced a new coupling which the company describes as having a flat-face twist lock for the toughest applications in the construction and demolition segment. This quick connect coupling is designed to work with the highest surge flows and the toughest pressure impulses, the company says.

The TLX series is made from high alloy steels with zinc-nickel surface treatment for durability in adverse conditions. The series is available in sizes from ¾" to 1 ¼" to cover most applications.

High surge flows are one of the key reasons that screw-to-connect couplings fail in heavy duty applications, according to the company. For example, when using a crusher on concrete operators will build up high pressure just before biting through the concrete. The moment the crusher bites through the concrete, an extreme surge flow briefly occurs. This surge flow can be several times higher than the ordinary flow rate in the machine and is the cause of many coupling failures. The popular but makeshift solution has been to use bulky oversized couplings at higher costs than specialised equipment.

The CEJN TLX has its roots in a patented design with verified performance over many years in industrial auto-couplings which are connected at full working pressure on both sides and used in tough impulse applications, says the company. The design of the TLX valve package is highly robust and the seals are protected from being flushed away by surge flow. The coupling is designed with a round thread profile but without sensitive eliminators or complicated locking systems.

The flow rate of the TLX is not limited to a certain level as it can handle high flow without failures, according to CEJN.
