Overview
All of Corken’s regenerative turbine pumps are known as a Coro-Flo®. The DL-/DLD-/DLF-model regenerative turbine pump is a direct mount made for a standard, two pole C-Face motor with a 8.5″ rabett diameter. A 8.5″ rabett diameter fits 182TC, 184TC, 213TC and 215TC motor frames. The direct mount supports both the pump and motor so they can be directly coupled. Since the it is designed to exact tolerances of the pump and motor, simple assembly will result in proper alignment of the pump and motor shaft. The advantage of a direct mount is no coupling guard, baseplate, or special alignment procedures are required for installation.
The DL-model comes with the standard NPT connections. The DLD-model has DIN flange connections while DLF-model has ANSI flange connections. All of these pumps are designed for liquefied gases such as LPG (propane & butane) agricultural ammonia, natural gas liquids (NGLs), CO2, SO2, refrigerant gases, and many other many more.
