Gas connection assembly

The Gas Connection Assembly connects the sparger to a gas supply manifold. The Gas Connection Assembly terminates in Quick-connect gas fittings with inbuilt non return valves, to prevent gas escaping from the system in the event of accidental release of either end of the hose. An additional check valve is provided prior to the sparger assembly to provide failsafe protection of the hose and gas manifold against slurry ingress. The connection hose is a stainless steel braided PTFE hose designed for long life.

 

 

Wet end sparger assembly

The sparger is manufactured from stainless or alloy steel pipe and provides an unhindered flow path. There is no need for any internals to prevent slurry ingress. Leak free connection to the gas connection assembly and the insertion assembly is ensured with the use of custom made fittings.

A wide range of sparger pipe lengths ensure injection of the gas into the ideal mixing zone, which is not necessarily directly underneath the agitator. Custom made sparge pipe lengths are also available to order.

 

 

Insertion Assembly

The Insertion Assembly is a high specification system designed to make live removal and insertion safe. It consists of three key components:

• EPDM check valve – a self-closing valve which fits inside the tank nozzle on the side of the process vessel to prevent slurry leakage.
• Dual pipe seals – a redundant feature to prevent slurry loss whilst retracting or inserting the sparge pipe.
• A full port ball valve for isolation purposes.
