Extremely quiet and free of vibration and pulsation, the Coro-Flo pump provides trouble-free service and long life. For low-capacity, medium-head pumping such as cylinder filling, the C-Series is the pump of choice.

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 ac-celerated 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 main-tenence on these pumps is easy and very infrequent.

Same features and reliability as the “C” models but used for base mounting with standard foot mounted motors. Motor volt-age, phase etc. can be selected to suit the individual application. Commonly used to feed vaporizing and aerosol systems.

The FF075 and FF150 pumps are designed for larger capacity or higher differential pressure applications. Exceptionally well suited for larger motor fuelling, vaporizer feed systems in both aboveground and underground tank applications.

Corken Coro-Vane Stationary Pumps

Corken Coro-Vane Sliding Vane 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.

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 sup-ported 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.

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.

Pump Accessories

Blackmer Bypass Valves

Pump Checkout Procedure

Blackmer differential bypass valves are designed to protect pumps and system components from excessive pressure damage. Five sizes are offered to provide full flow capacity up to 250 GPM.

Valve “A” must be open. Verify that the excess flow valve has not inadvertently closed.

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 pres-sure after pump is started with valve “C” open

Throttling valve “C” will dead head the flow and allow the operator to judge the highest pressure increase the pump is capable of producing.

Reopening valve “B” will allow the operator to do a final reset of the bypass valve.

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.

Fisher Absolute Bypass ValvesCertain 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 atmo-spheric pressure and fill the need for this type of application.

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.

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.

Common applications include grain dryers, construction heater loads or any vaporized gas application requiring a presssure boost.
