Flex-Flo™ Feed Delivery Systems

Nothing beats Cumberland's Flex-Flo™ feed delivery system in flexibility and adaptability. Using PVC tubing as the carrier of feed not only provides flexibility in facility design, but reduces dust, provides protection against insect and rodent contamination, and reduces stressful operation noise.

Multiple Models

Both tubing and augers are available in four sizes and five models with capacities ranging from 15 lbs. to 220 lbs./minute (6.8 kg to 99.8 kg/min.). Whether it's ground feed, crumble feed, mash, high moisture corn, shelled corn or pellets, Cumberland has the equipment to handle it.

System Efficiency

Cumberland offers several unloader systems including single, twin, tandem and twin tandem models. The Flex-Flo auger can be direct or belt driven by a 1/3 to 1 - 1/2 horsepower, totally enclosed fan cooled motor at a standard 358 RPM (other speeds are available for special applications). A wide selection of accessory equipment is also available including extension hoppers to adjust auger lengths, time clocks, automatic shut-off switches, intermediate drop kits, and y-drops.

Power Units

The Flex-Flo™ auger is driven by a 1/3 to 1-1/2 horsepower, totally enclosed, fan cooled motor at a standard 358 RPM (other speeds are available for special applications). Whether direct or belt driven, the drive system includes an easily accessible maintenance port, a safety back-up switch to automatically stop and restart the motor if feed backs up in the line (a warning light will notify you that this is occurring) and an automatic thermal shut-off switch which allows you to restart the system when the motor has cooled off. All electrical connections are safely housed in a plastic, water-resistant control box.

Flex-Flo™ PVC Tubing

Cumberland's polyvinyl chloride (PVC) tubing is mixed and formed in our own facility to our exacting standards under strict quality control. Blending our own PVC allows us to formulate the optimum compound for UV stabilization, strength, and wear resistance.

Cumberland's Flex-Flo™ PVC tubing is capable of spanning distances of up to 150' with most models and 250' with the 220 Model. For applications requiring distances greater than the standard length of any given system, extension hoppers are available that can expand the delivery range to practically any distance and can provide access 90 degrees from the main line.

Quality Auger

Cumberland augers are coiled in-house from high tensile steel. Our steel wire is flattened prior to hardening for a more consistent, higher quality product.

Universal Sensor

Cumberland's Universal Sensor is truly universal. It adapts to control voltages from 24 to 240 volts and can operate either normally open or normally closed. This switch utilizes technology that is not sensitive to changes in temperature or humidity, eliminating the need for a sensitivity adjustment. The convenient push button interface allows you to quickly and precisely program an on delay from one second to three hours to prevent short cycling of the feed system. LED's indicate the status of the switch at all times.

Maximum Run Timer

Cumberland's Maximum Run Timer prevents costly feed spills and auger wear by shutting down the feed line if the system operates longer than the programmed run time. An indicator light alerts you to why the system was shut down. The reset button allows the auger to be restarted after the problem has been corrected. The run timer easily adapts to any flexible auger system.
