1-KDN

Summary

Product Identification

The DAB PUMPS 1-KDN series comprises fire-fighting booster sets designed according to the European standard EN 12845. These units are modular in design, allowing for various configurations to meet the standard's requirements for sprinkler systems.

Available modular booster set versions include:

• 1 KDN .... EN: Composed of 1 electropump.
• 1 KDN .... EN-JET: Composed of 1 electropump + 1 jockey pump.
• 1 KDN MD EN: Composed of 1 Diesel pump.
• 1 KDN MD EN-JET: Composed of 1 diesel pump + 1 jockey pump.

Joint manifold kits are available as accessories to arrange booster sets with 2 or 3 pumps, as expected by EN 12845.

Compliance and Standards

• Designed and manufactured according to European standard EN 12845.
• A Declaration of Conformity to Standard EN 12845 is provided with each group.
• The user is responsible for carrying out inspection and check programs, arranging test, service, and maintenance schedules, and keeping records.
• The installer must provide the user with a documented inspection and checking procedure, including emergency manual starting instructions.

Main Components

The booster sets are composed of:

• Eccentric connection unit fixed on independent suction port of the pump.
• Standardized KDN series centrifugal pumps (with spacer coupling), conforming to EN 12845.
• Electrical or diesel motor, sized to supply the maximum power absorbed by the pump.
• Detection of diesel engine rotation (speed sensor).
• One control panel for each pump, equipped with:
  • Voltmeters and ammeters
  • 2 starting batteries
  • 2 battery charge control units
  • Rev counter
  • Hour counter
  • Man-0-Aut selector
  • General switch
  • Warning lights
• Control panel for jockey pump (if present).
• Fuel diesel tank with capacity to guarantee 6 hours of operation (for diesel versions only).
• Check valves.
• Jockey pump (if required), JET or KVCX series, for small pressure drops, complete with 1 expansion tank.
• Flow meter (optional), to be installed on the delivery manifold.
• Galvanized steel base.
• Galvanized steel delivery manifold, complete with starting pressure switches, by-pass circuits, and pressure gauge.

Electrical

Electrical pump models are specified for 400V, 50Hz, three-phase (T400/50). Motor power ratings for electrical pumps range from 5.5 kW up to 110 kW.

Mechanical / Hydraulic

• Pumps: KDN series centrifugal pumps, with optional JET or KVCX series jockey pumps.
• Fuel Tank: Diesel versions include a fuel tank with a 6-hour operating capacity.
• Connections:
  • Suction Nominal Diameter (DNA) options include 80 mm (2"), 100 mm (2"1/2), 125 mm, 150 mm, 200 mm, 250 mm.
  • Delivery Nominal Diameter (DNM) options include 2", 2"1/2, 80 mm, 100 mm, 125 mm, 150 mm.
