Overview

All of Corken’s regenerative turbine pumps are known as a Coro-Flo®. The MDC-model (Magnetic Drive Coro-Flo) is a stainless steel turbine pump with a sealless magnetic drive configuration. The close-coupled magnetic drive pump mounts directly to a Corken supplied C-Face motor so no coupling or special alignment procedures are required. Installation is quick and easy. A close-coupled design is a great option when space is limited. With a sealless design there are no mechanical seals so you get maximum liquid containment when handling corrosive and toxic liquids.

 

MDC-model turbine pumps are designed for low capacity, medium head pumping applications involving corrosive liquefied gases such as aqueous and anhydrous ammonia, carbon dioxide, sulfur dioxide, chlorine, hydrogen chloride and many more.

 

The MDC-model industrial pump is designed for simplicity of inspection and service. All maintenance can be performed by simply draining the pump using the drain port and removing the pump cover. Since the impeller is the only moving part, downtime and maintenance costs are minimized. Available with NPT and slip weld connections.
