Autogas Pumps

The autogas market is unique with its own distinct needs. With the aid of marketers, designers and installers of autogas systems, Corken has designed a pump to meet those needs.

Model FF075 (frame mount)

Corken autogas pumps achieve new levels of performance by delivering more capacity at high differential pressures, non-pulsating and quiet transfer, longer pump life and ease of maintenance. Versatility is a key part of the pump design and makes it a great fit for other applications such as cylinder filling, vaporizer feeding and bulk transfer.

Advantages

Ideal for dual hose dispensers and multiple dispensers	Metric fasteners
ANSI or DIN flanges (DLF vs. DLD)	Ductile iron case
Continuous duty capability	Designed for 50 and 60 Hz
Self-aligning, free-floating impeller	Single mechanical seal
Heavy duty bearings

Mounting Options
The DLF and DLD models are direct mounted with C-face electric motor as shown to the right. The foot mounted version above is mounted on a baseplate and can be direct driven through a coupling to a 2,880/3,600 RPM motor or through a V-belt drive.

Superior Design
The autogas pumps are designed to be extremely quiet and free of vibration and pulsation. The one moving part, the impeller, floats on the shaft without contacting adjacent surfaces, thus extending pump life. These factors contribute to trouble free service and long life exhibited by the autogas pump

Long Life and Ease of Maintenance
The autogas pump has design features and a rugged ductile iron construction for long life. The design of the pump also readily accommodates standard maintenance. The mechanical seal can be replaced in minutes.

Applications

T-style compressors can handle the same applications as a D-Style compressor. These include transfer of liquids between tanks, off-load/load out liquids, recover residual vapor, pressure boosting, etc. The T-style, however, offers the advantage of precise leakage control. The T-style compressor was designed to provide maximum leakage control when handling toxic, hazardous, and explosive gases.

Options

Corken offers a broad range of material options. Corken also offers various corrosion resistant coatings, valve options, and equipment configurations. Corken supplies custom engineered packages as well. Skid mounted units can be supplied with control panels, safety controls, receiver tanks, liquid traps, and other special accessories as required.

Self-lubricating teflon piston rings
Ductile iron construction
Positive piston rod/packing alignment
O-ring gaskets
High-efficiency valves
Purge or pad capability

Double distance piece (T-Style)
Designed for improved leakage control, this option has three separate sets of packing per piston rod which effectively form two distinct distance pieces or barriers to external leakage. Each distance piece has its own line connections and can be separately pressurized, purged or vented to provide a wide range of application flexibility. For added convenience, purge kit options are available that include all the accessories needed to control the purging or pressurization of each chamber.

Serviceability

Industrial Coro-Vane Series Pumps

Corken manufactures variations of its positive displacement, sliding vane design for various applications. Each of these offers unique features for the transfer of hazardous, non-lubricating liquefied gases and low viscosity liquids. For more information, review the various pump styles offered by Corken below.

Low Pressure CP Series Pumps: These pumps are designed for operating pressures up to 200 psi (13.8 bar) and flow rates up to 400 gpm (1,514 L/min). They are ideal for various petroleum products with low vapor pressures such as petroleum based oils and fuels. These pumps are also capable of handling numerous thin liquids such as alcohols or solvents.

High Pressure CD Series Pumps: These pumps are designed with a ductile iron construction for operating pressures up to 400 psi (27.6 bar) and flow rates up to 400 gpm (1,514 L/min). They are ideal for applications involving liquids at elevated pressures such as liquefied gases. CO2, ammonia, and various freons are examples of such liquefied gases. These sliding vane pumps were specifically designed for the transfer of such liquids.

Magnetic Drive Series Pumps: These pumps are offered in CP and CD versions which cover the range of operating pressures described above only with a seal-less design. This magnetic drive pump is ideal for pumping hazardous, toxic, foul smelling or other difficult to seal thin liquids.
