ByPass Valves

B166 (3/4″ and 1″) Automatic Dual Purpose, Bypass Valves

Applications
Used with all cylinder filling pumps. (Coro-Flo Models and low flow side channel pumps)

The B166B is a combination bypass and priming valve specifically designed for small cylinder filling type pumps, especially of the regenerative turbine type, such as the Coro-Flo pump series. The vapor elimination system keeps liquefied gas pumps primed to increase system reliability and decrease pump and seal wear. The B166B is a smooth operating bypass with moderate pressure buildup.

T166 (1-1/4″ and 1-1/2″) Pump Flow Control Valve

Applications
Used with large capacity pumps filling various sizes of tanks and bottles such as those used with delivery trucks or multi-spot cylinder-filling plants.

The T166 valve provides smooth-acting flow control. Specifically designed for bypass protection for pumps in the 30–100 GPM (6.8–22.7 m³/hr) range, such as those used on delivery trucks. In contrast to the B177, the T166 valve opens gradually as pressure builds up to modulate the flow, bypassing the excess capacity smoothly and silently back to the supply tank. A continuous internal bleed in this valve assists in eliminating vapors.

B177 (2″ and 2-1/2″) Differential Bypass Valve

Applications
Used in liquefied-gas bulk plant installations for the loading and unloading pumps.

The B177 is a low-pressure buildup valve specifically designed for applications requiring protection for positive displacement pumps in the 50–350 GPM (11.4–79.5 m³/hr) for smooth-acting flow control. To properly function, this valve requires a pressure sensing line for the storage tank. This valve should be applied where horsepower is limited and accuracy set points and flow points are necessary.

Z-Series Pumps

Z-Series Z3500 Stationary and Truck Pump

Z3500 Overview

Save time and money with higher flow rates—faster loading and unloading!

The new three-inch Z3500 LPG pump is designed for stationary and foot mounted truck applications. The Z3500 stationary pump has the same locked rotor design used in the Corken Z-Series truck pumps to ensure long pump life and excellent performance. With higher flow rates than other three-inch pumps, the Z3500 retrofits Corken’s and other competitive pumps with little or no change in piping.

Z-Series Z3500 Stationary and Truck Pump

Z4500 Overview

Higher capacities shorten fill times for transports and multiple bobtail loading

The Z4500 is a four-inch stationary pump designed for transport loading and multiple bobtail loading applications. If you have two or more bulkheads to load bobtails and transports and would like to shorten your fill times, then the Z4500 is the stationary pump for you. The Z4500 can fill two 3,000 gallon bobtails in 20 minutes or less at typical operating RPMs.

SC-Series Side Channel Pumps

SC-Series Side Channel Pumps are typically used for cylinder filling, vaporizer feeding, pumping from underground storage and bulk filling operations.

Applications
For those LPG applications where high-differential pressure is necessary or low NPSH conditions exist, such as pumping from underground tanks, the SC-Series multistage side-channel is the pump of choice.

Flexibility
The side channel pump is offered in six different sizes, each ranging from one to eight stages. This provides for a wide range of pressures, capacities, and liquid transfer rates.

Design
The Corken SC-Series pump line utilizes an integral centrifugal and side channel design to create flow characteristics which enable the pump to handle up to 50% vapor and low NPSH conditions. The multi-stage modular side channel design which features one to eight open radial-vane impellers is capable of building differential pressures of over 200 psi (14 bar).

Coro-Vane Stationary Pumps

Corken Coro-Vane^® pumps are positive displacement pumps. They produce a maximum differential pressure of 125 psig (8.6 bar g). Corken manufactures four sizes of Coro-Vane pumps, ranging from 1gpm to 350 gpm (0.2–79.5 m³/hr). Corken offers these pumps with v-belt or direct-drive mounting options.

Applications
Typical applications for the Coro-Vane^® pump include cylinder filling, loading and unloading of bulk trucks and transport trailers.

Long Life and Ease of Maintenance
The pump housing and rotors are constructed of ductile iron for extra strength and long life. The sliding vanes are self-adjusting which allows for longer life and higher efficiencies throughout the life of the pump. The pump design includes removable pump casing cams (liners) which when worn can be replaced in minutes. The seal and bearings can be replaced in minutes by simply removing four bolts. Some of the models are equipped with an internal relief valve.

Mounting Options
Corken offers the option of belt drive or gear drive with reducer. The Coro-Vane® stationary pumps are designed to run up to 950 RPM. The C51/F51 bottle filling Coro-Vane pumps are designed to run at 1800 RPM.

Coro-Flo Pumps

The Coro-Flo® pump is offered in three different model drive configurations. The C-Model configuration has the pump close coupled to a motor (shown below). The F-Model has a separate pump body and is directly driven through a coupling. And finally, the DS/DL Model pumps are mounted on a special bracket which will accept standard C-face motors.

Designed specifically for LPG, the
C-Modelpump is extremely quiet and free of vibration and pulsation and provides trouble free service and long life for volatile liquids such as LPG. The one moving part, the impeller, floats on the shaft without contacting adjacent surfaces, thus extending pump life. All Coro-Flo® pumps are listed by Underwriters’ Laboratories, Inc. for LP-Gas and anhydrous ammonia service.

The F-Modelpump is the base plate mounted version. Coro-Flo® pumps are design to operate at shaft speeds between 2880—3600 rpm. The F-Model provides the flexibility of motor selection.

The DS/DL Model pumps are designed to eliminate the need for a baseplate, coupling guard, and coupling alignment which makes the DS/DL series pumps compact and easy to install. The special bracket supports both the pump and the motor so they can be directly coupled.

The Coro-Flo® pumps have an option of ANSI flange connectionson all of the various sizes and model types.

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.
