Firematic Eductors

Rural fire companies need creative solutions to utilize water sources that are not accessible using typical drafting techniques. The Fire Eductor allows fire companies to tap into water supplies like ponds, streams, and swimming pools up to 250’ away and can generate flows up to 670 GPM. Larger Image

To put the unit in operation, a 2½ inch hose line and a 5 inch LDH supply line are stretched from the fire truck with the eductor to the water supply. The eductor is placed in the water and the motive line is charged to 150 psig. This immediately starts the flow of water back to the fire truck through the 5 inch LDH supply line. Once the suction flow is established, the first portion of the flow is used to replenish the tank water in the truck. Once the tank has been replenished, the water supply has been established and water can be supplied for use on the fire. The unit was designed for 17.5 feet of head and during our prototype testing, we were able to achieve 750 gpm net suction gain. We supplied 200 gpm at 150 psig to the eductor, 750 gpm was developed as a suction flow with a total flow back to the fire truck of 950 gpm. 200 gpm of the 950 gpm was being recycled back to supply the eductor. TurboDraft setup is quick and simple.

FIRE FIGHTING APPLICATION CHALLENGES:
1. Access to a water source is more than 30 feet and typical drafting techniques cannot be implemented
Solution A Solution B
By stretching a 2 1/2" supply line and a 5" or 6" return line, usable water supply of 600 GPM or more can be achieved at a distance of over 100 feet. Actual usable water supply will be determined by discharge line loss and elevation differences between water source and pump suction. Utilize a portable pump or truck mount pump on a field truck to supply the TurboDraft Fire Eductor.  Achieve usable fire flows of 800 GPM or more.
Solution C Solution D
Small portable pumps can be operated in parallel to support the 200 GPM supply requirement and achieve 800+ GPM usable water supply. Permanently install TurboDraft at the base of a dry hydrant to overcome friction and elevation losses to increase dry hydrant output. Fire flows at elevations up to 40' can be achieved.

2. Due to congestion at the fire scene, portable tanks for tanker delivery need to be set up at remote location
TurboDraft can be used in conjunction with a portable pump to provide constant flow between remote tanks and fire scene supply tank. Flow from the remote tanks can be controlled by a gate valve in the 5" supply line. If discharge line is blocked, supply line flow is discharged into portable tank and recycled.
3. Elevation between water level and fire truck position prevents the use of traditional drafting technique or dry hydrant installation
Install a dry hydrant equipped with a TurboDraft unit. By connecting the pump suction to the dry hydrant with a hard sleeve, usable suction flows of 600 GPM can be attained at 35 feet of elevation.
4. Flood mitigation and water transfer
TurboDraft can also be employed in emergency flood situations. TurboDraft's ability to transfer large volumes of water in a short amount of time makes it a critical piece of equipment for dewatering basements and other low-lying areas where water collects.

Notes:
  1. Theoretical, based on test curves of 9/21/99 and hose friction loss per NFPA® Fire Protection Handbook, 15th Edition, Table 17-7H, actual friction losses may vary depending upon hose and coupling design/manufacturer.
  2. All flows achievable with 1,000 GPM rated pumper based on NFPA recommended pump curves. Use larger pumper where maintenance/ performance is questionable.
  3. Minimum available flow from a water source recognized by ISO for grading purposes is 250 GPM. ISO does not recognize drafting sources requiring a lift in excess of 18' (This is not a drafting device as it operates under pressure.)
