Having a reliable source of emergency backup flow is critical for any high temperature equipment. During a commercial power outage or pump failure, the loss of coolant flow can quickly cause equipment damage. Shown at right is a natural gas powered engine pump that delivers 1,000 GPM @ 40 psi. Shown below is a smaller version for 350 GPM. Both systems include all controls for autostarting in the event of power loss.

ENG Series Engine Pump

  • Fully Automatic Operation
  • Starts Upon Loss of Electrical Power
  • Wide Range of Sizes Available
  • Compact Unitized Design
  • Natural Gas, Propane or Gasoline Fired
Safe Operation - Even when the lights go out . . .


An emergency city water option is available for backup cooling upon loss of flow or loss of electrical power. This option includes a fail-open valve for city water supply, a water driven turbine pump and a shell and tube heat ex chang er. This provides backup flow and cooling for safe op era tion on critical duties such as cooling bearings and seals on high temperature furnaces or any application where you can't afford to go down.


  • Centrifugal Circulating Pump
  • Water Driven Turbine
  • Shell and Tube Exchanger
  • Fail Open City Water Inlet Valve


Diaphragm pumps are frequently used for backup coolant circulation in systems requiring low emergency coolant flow (typically less than 100 GPM) and where a reliable supply of plant air or inert gasis readily avail able. A fail-open solenoid controls starting of the pump.
