This Edwards water cooling unit is optional on the nEXT730D and nEXT930D turbo pumps, and is included standard with nEXT1230H pumps. The water cooling block slides into a slot in the base of the pump and is secured with 4 M4 screws. This water cooling block has push-fit connectors for the supply and discharge hoses (8mm OD plastic hose). The hose connections may be unscrewed and removed to make use of the integrated G 1/8” threads. This water cooling kit is needed when using a flange heater band with a CF flanged pump. Edwards nEXT turbo pumps also benefit from water cooling when there are high gas throughputs, cyclic operations and/or high ambient temperatures. In order to ensure long trouble-free operation, the cooling water must be clean and not contain any oils, greases or suspended solids. This water cooling kit has Edwards part number B8J200820.

This water cooling unit fits:

• nEXT730D turbo pumps
