Corken – Z4500
- 1,446 L/min
- 24.1 bar
- 107°C
The model Z4500 (4″ Class 300 RF flange) is a stationary pump designed for large loading and unloading applications. When using two or more bulkheads to load transports or multiple bobtails, the Z4500 can shorten the fill times. To protect the pump form excessive pressure buildup, all of the Z-Series stationary pumps are equipped with a built-in internal relief valve. In the event the discharge

Corken – Z2000
- 287 L/min
- 6.9 bar
- 107°C
A two inch foot-mounted pump with NPT flanges. The pump is securely mounted on a steel frame fixed to the truck’s chassis and piped from the internal valve on the truck’s tank. To limit the length of the power take-off drive line, the Z2000 is typically installed close to the power take-off box between the front of the truck’s tank and the cab of the truck.

Corken – F (Coro-Flo)
- 136 L/min
- 27.6 Bar
- 400 SSU
The Corken Coro-Flo was originally developed to fill propane cylinders, but it has found its way into many other fields, especially where volatile liquid transfer is involved. It is commonly used to feed aerosol filling lines, and to transfer liquefied gases like NH3 CO2, SO2 and the refrigerant gases.

Tech Data
- Pumps 2 to 36 gpm (7.6 to 136 L/min)
- Heads to 700 ft (213 m)
- Max. RPM 3600
- Max. pressure: 400 psig (27.6 Bar)
- Temperature: -25° to +225° F (-32° to +107°C)
- Max. viscosity 400 SSU
- Case/cover: Ductile Iron ASTM A-536
- For thin liquids & liquefied gases: Propane, Butane, Ammonia, Refrigerants, Sulfur Dioxide, Carbon Dioxide, Gasoline Light Oils, Solvents, Propylene, Pentane, Foam Blowing Agents
- Application: ideal for research laboratory work and for handling many liquids of the petrochemical, lpg, nh3 and aerosol industries.

Corken – FF150
- 85 L/min
- 10.0 bar
Regenerative Turbine Pump. The mechanical design of the regenerative pump closely resembles a typical centrifugal pump. The lightweight impeller allows an overhung impeller design to be used. This design requires only one mechanical seal to seal off the pumping chamber. The impeller is designated to float on the shaft so hydraulic forces in the pump may perfectly center the impeller to prevent metal to metal contact between the impeller and casing. A free floating impeller is much easier to install than a centrifugal pump impeller.

Corken – Standard Model Sliding Vane Pumps
- 1,457 l/min
- 24.1 bar
- 107°C
- 4,250 cSt
Corken’s standard model sliding vane pumps utilize the original ten blade design with no blade drivers. The mechanical seal now has a silicon carbide seal seat providing maximum leakage control and is approved for propane, butane, and agricultural ammonia. Suitable for bulk pump transfer and propane delivery truck applications. Available in 2” and 3” sizes.

Corken – Z (Sliding Vane Pumps)
- 1,457 L/min
- 24.1 bar
- 107°C
- 4,250 cSt
The Z-Series Coro-Vane® pumps offer a six blade design with blade drivers and a patented needle roller thrust bearing rated for 4,000 lbs. The needle roller thrust bearings protects the pump against dynamic impact loads imposed on the pump by the drive system. Premature failures due to axial thrust loads are minimized on truck applications. With O-ring construction throughout, they are rated for 400 psi (28.6 bar) working pressure. Since the Z-models sliding vane pumps are used primarily in LPG (propane & butane) and agricultural ammonia applications, the non-adjustable internal relief valve is pre-set at the factory and does not require adjustments in the field.

Z-Series pumps are a great option for other liquefied gases with high vapor pressures such as natural gas liquids (NGLs), refrigerants, CO2, and many more. Applications include bulk pump transfer, propane delivery truck, and transport. Available in 2”, 3” and 4” sizes.

When an electric motor drive is not the preferred option, there are alignment issues, or space is limited, a hydraulic drive is the solution. This option allows the user to mount a hydraulic motor directly to the pump forming a precise compact alignment. The hydraulic drive option is available on Z-Series pumps only. The lettter “H” shown in the model number (e.g. ZH2000) designates the hydraulic drive option.
