Dynamic Sealing in Chemical Process Pumps

Flowserve Chemstar Repeller and the Mark 3™ Sealmatic pumps feature dynamic sealing technology, enabling pump operators to significantly reduce the total life cycle cost of process pumps in demanding services, such as:

•         Unspared continuous-duty applications, e.g., recirculation in starch conversion
•         Applications in which seal flush is undesirable, such as evaporator feed service and ethanol production
•         Hard-to-seal liquids — sodium hydroxide mineral acids, phosphoric acid and sulfuric acid, for instance
•         Liquids containing solids
•         Batch operations like tank unloading where run-dry conditions might exist
