This water cooling unit fits Pfeiffer HiPace 300 and 300H turbo pumps. It attaches to the side of the pump with two included bolts. 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 required when using a flange heater band with a CF flanged pump. Pfeiffer HiPace 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 unit has Pfeiffer part number PM 016 624-T.
