Dayliff FLEN Fire Sets - Dayliff | Dependable Quality

Product Overview

Product Details

DAYLIFF FLEN packaged Fire Sets are specially designed to provide automatic water supply to fixed automatic sprinkler firefighting installations. Pump sets combine single duty diesel and electric powered supply main pumps to ensure serviceability in all conditions as well as a jockey pump to maintain system pressure. The fire sets are certified by KEBS for assembly in conformity to BS EN 12845 standard to ensure high reliability. Particular features include:-

  • Individual electric motor and diesel engine powered pump sets providing standby supply in event of electrical power failure.
  • Separate automatic jockey pump to maintain system pressure restricting start of main pumps to at least one open sprinkler.
  • Independent control panels for each pump with EN 12845 compliant control units.
  • Double self-disabling type pressure switches providing automatic starting of the main electric and diesel pump(s)
  • Main pumps of back pull-out design and stable curves with spacer couplings to allow inspection of the hydraulic parts without disconnection of the piping, motor, or engine
  • Vibration dampening system on diesel engine-driven pump sets consisting of rubber anti-vibration expansion joints that reduce the amount of the vibrations produced by the diesel engine reaching the system.

For all firefighting applications high levels of equipment performance and dependability are vitally important for the protection of both lives and property. Dayliff FLEN Fire Sets combine quality components for optimal operational efficiency with high pumping efficiency and competitive pricing to provide effective, reliable, and easy to install firefighting solutions certified to accepted insurance performance standards.
