Pumps and Compressors

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.

Operating Specifications

• Flow rates up to 23 gpm (87 l/min)
• Working pressures up to 300 psi (20.7)
• Differential pressures up to 250 psi (17.2 bar)
• Temperature range: -150 to 450 °F (-101 to 232 °C)
• Viscosities up to 32 SSU (6.8 cSt)

Corken’s regenerative turbine industrial pump is known as a Coro-Flo®. The Coro-Flo turbine pump is a continuous duty design and is a great choice for lower flows and moderate to high differential pressures. The liquid is circulated between the teeth of an impeller that rotates between the pump casing and head. Since the Coro-Flo is designed with a free-floating impeller, there is no metal-to-metal contact so the maintenance requirements are minimized. Corken offers several models of regenerative turbine pumps for wide range of differential pressures, and capacities.

Our Coro-Flo turbine pump was originally developed to fill propane cylinders. Over the years it has found its way into many other applications—especially where volatile liquid transfer is involved. It is commonly used as a vaporizer feed pump, aerosol propellant pump, and propane cylinder filling pump. Suitable for light liquids such as gasoline, solvents, and light oils and liquefied gases such as ammonia, carbon dioxide, sulfur dioxide, propane, butane, and refrigerant gases.

Each product group below is designed for specific capacity and mounting configuration. To find a regenerative turbine pump for your application, select one of the product groups listed below.

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.

HDP (High Differential Pressure) Turbine Pump Packages Overview

Standard HDP Package For Three Phase Electrical Power

If you already have three phase electric power, then our standard HDP turbine pump package is for you. Since three phase power is sufficient for operating the larger horsepower motors required for high differential pressure applications, the standard HDP does not include the variable frequency drive (VFD). Three phase electric will provide the power needed for building 125 to 250 psi (8.6 to 17.2 bar) of differential pressure.

Optional HDP Package For Single Phase Electrical Power

If you are limited to single phase electric power and your pumping application requires high differential pressures, then the optional HDP turbine pump package is for you. With the optional HDP package you get a variable frequency drive (VFD) that allows you to convert a single phase electrical power to three phase power. Three phase electrical power is necessary to operate the larger horsepower motors required for building 125 to 250 psi (8.6 to 17.2 bar) of differential pressure.

A Variable Frequency Drive (VFD) Offers Many Features & Benefits…..

• Easily converts single phase a source to three phase service
• Slow start-up feature eliminates flow surges
• Variable motor speed capability maximizes pump performance
• Includes motor overload protection to minimize potential damage
• Shipped pre-programmed at 60 Hz with 4 second ramp-up speed
• Magnetic starter is not required so your installation costs are minimized
• A standard remote switch is available

Ideal HDP Applications Include….

• Aerosol filling stations
• Autogas filling stations
• Cylinder filling stations
• Propellant
• Vaporizer feed

HDP Turbine Pump Packages Are Available In Three Models

Overview

All of Corken’s regenerative turbine pumps are known as a Coro-Flo®. An F-model turbine pump is a frame mount design and requires a baseplate. A frame mount utilizes a direct drive configuration that runs at motor speed and requires a coupling and coupling guard. With a frame mount design, you have the flexibility to choose from a variety of motor types. This turbine pump is designed for liquefied gases such as propane, butane (LPG), agricultural ammonia, natural gas liquids (NGLs), CO2, SO2, refrigerant gases, and many other many more. FF- & FD-models 060, 075, and 150 produce a higher differential pressure than our standard F model pumps and are commonly used in autogas filling stations.

Operating Specifications

• Flow rates up to 50 gpm (189.3 l/min)
  
• Working pressures up to 400 psi (28.6)
• Differential pressures up to 250 psi (17.2 bar)

All of Corken’s regenerative turbine pumps are known as a Coro-Flo®. The C-model  turbine pump is a close-coupled design that mounts directly to a Corken supplied C-Face motor so no coupling or special alignment procedures are required. With a close coupled design, installation is quick and easy. C-model turbine pumps are designed for low capacity, medium head pumping applications involving liquefied gases such as LPG (propane & butane), CO2, and refrigerant gases. Since the compact,close coupled design is ideal for tight spaces, the C-model Coro-Flo is the pump of choice for dispensing applications like propane cylinder filling stations.

The D- and F-model sliding vane pumps have a working pressure of 350 psi (25.2 bar) are ideal for low flow applications involving light liquids. Unlike the CP-, CD- and Z-models, they do not have a replaceable cam but you can replace the sideplates. The internal relief valve is adjustable and there are a wide variety of mechanical sealing options. Available in a 1” inlet and a .75” outlet only.

The D-model sliding vane is a bare pump that can be close-coupled to any NEMA 56 or 66 C-face motor. With a close-coupled design, there are no special alignment requirements so installation is quick and easy. An F-model sliding vane pump is a frame mount design that is mounted to a baseplate and requires a coupling and coupling guard.

Hydraulic Drive Option Overview

When an electric motor drive is not a preferred option, misalignment has been an issue, or you have limited space, the hydraulic drive is a great solution. This option allows for direct mounting of a hydraulic motor and forms a compact alignment. The hydraulic drive option is available with the CP-, CD-, PT-, PZ- and Z-model product groups. The hydraulic drive configuration is designated by the lettter “H” within the model number. The model numbers for our hydraulic drive sliding vane pumps begin with CPH, CDH, PTH, PZH and ZH. The operating specifications for the hydraulic models are the same as the standard CP-, CD-, PT-, PZ- and Z-models. For details on the operating specifications, refer to the pages containing our standard models.
