Corken Pumps
Corken Coro-Flo Regenerative Turbine Pumps
The regenerative turbine pump is the most dependable LP gas pump on the market.
The free floating impeller with teeth cut on both sides picks up the fluid and creates
a spiraling motion around the circumference of each side. The fluid is slightly accelerated and pressurized in dozens of small steps creating a smooth, quiet, overall
product flow. With only a single pump seal and it’s free-floating impeller, the maintenence on these pumps is easy and very infrequent.
Corken “C Series” Coro-Flo Pumps
Extremely quiet and free of vibration and pulsation, the Coro-Flo pump provides trouble-free service and long life. For lowcapacity, medium-head pumping such as cylinder filling, the C-Series is the pump of choice.

Corken Pumps
Corken Coro-Vane Sliding Vane Pumps
The sliding vane pump is the most popular type of pump in the LP gas industry for
higher flow rate applications. In this type of pump, a slotted rotor is eccentrically supported in a cycloidal cam creating a crescent cavity between the rotor and the cam.
The sliding vanes sweep the incoming fluid to the opposite side of the crescent where
it is squeezed through discharge holes in the cam toward the pump outlet.
Because the vanes must always firmly contact the cam, special porting is designed
into these pumps which routes discharge pressure under the vanes to keep them
retracted from the rotor.
Corken Coro-Vane Stationary Pumps
Corken Coro-Vane pumps utilize the sliding-vane design to ensure pumping efficiencies remain high throughout the life of
the pump. The vanes are self-adjusting for wear. Coro-Vane pumps are positive displacement pumps. They produce up to a
maximum differential pressure of 125 PSIG. Three models are offered with capacities up to 350 GPM.

Corken Coro-Vane Truck Pumps
The Corken Z-Series truck pumps offer some remarkable improvements over competitive designs.
Rotor Centering - thrust bearings in addition to heavy duty roller bearings keep the rotor from grinding thru the endplates.
Blade Life - large diameter, low mass blade drivers won’t drive thru the blades even at elevated speeds.
Cavitation - new design blades, push rods and liner allow speeds up to 800 RPM.

Certain applications require a set line pressure that does not
vary with the pressure of the storage tank. Absolute bypasses
measure the difference between the line pressure and atmospheric pressure and fill the need for this type of application.

Pump Checkout Procedure
Checking the performance of a liquid propane pump is readily accomplished by recirculating the product flow and throttling
the discharge to determine the pressure capability of the system. The pump should be able to increase the tank pressure by at
least 80 psi without motor overload or pressure fluctuation.
If the system doesn’t have a pressure gauge, install one.
If the filling hose is too short to provide recirculation, get a longer one.
B
Valve “A” must be open. Verify that the excess flow valve
has not inadvertently closed.
C
The filling hose must be connected to valve “C” to allow
free circulation back to storage.
Valve “B” must be closed to eliminate the bypass circuit.
Pressure gauge “D” will show tank pressure with the
pump off. It will read a modest (20 psi) increase in pressure after pump is started with valve “C” open
A
D
CO
Throttling valve “C” will dead head the flow and allow
the operator to judge the highest pressure increase the
pump is capable of producing.
RK
EN
Reopening valve “B” will allow the operator to do a final
reset of the bypass valve.

Pressurizing Pump Sets
We assemble complete pressurizing pump sets for a wide variety of pressure and load requirements. These assemblies provide
a complete pump pressurizing package for continuos duty service with all components prepiped on a common base for ease of
installation.
Differential Pressure Applications
Absolute Pressure Applications
This style pump set is used where the load requires a
moderate boost in pressure above what the storage tank
can provide. A differential bypass regulates the boost
pressure. The dual check valve arrangement allows the
load to operate without the pump running with the option
of runing the pump when low storage tank pressures are
experienced.
This style pump set is used where an absolute line
pressure is required by the load. The absolute bypass
holds the delivery pressure to a constant value in contrast
to a differential value.
Common applications include hot mix plants, propane air
mixers or any vaporized gas application where a steady
pressure is required.
Common applications include grain dryers, construction
heater loads or any vaporized gas application requiring a
presssure boost.
