Description and technical characteristics

Firefighting pumped-tanker AZ-5,0-50 on chassis Ural-4320-79 is designed to deliver firefighting crew with a water–supply, foam agent and the fire–technical equipment to the place of fire origin. Fire extinguishing by water from the tank, reservoirs and hydrants, and by air – mechanic foam are available. The vehicle is equipped with pump unit LSA3000 which may be used both as standard fire pump and effective compressed foam firefighting system.

  • water supply (including seawater);
  • foam agent supply;
  • «wet» compressed foam supply;
  • «dry» compressed foam supply.


CAFS (Compressed Air Foam System) advantages:

  • increase of the firefighting and rescue potential of the firefighting vehicles;
  • reduction of fire extinguishing time (max. effect of CAFS is achieved on the first stage of operation);
  • reduction of the harmful environmental impact;
  • increase of the vehicle operation without refilling by reduction of the foam and foam agent volume;
  • possibility of the simultaneous operation from one fire pump both with water supply nozzles and foam nozzles;
  • possibility of compressed foam supply when working at high buildings;
  • economy of foam agent by usage of the more concentrated (1%) foam agents and exacting electronic inspection of the foam agent consumption.


LSA 3000 assembly:

The pump unit LSA 3000 consists of the following elements based on the frame in united module:

  • noncorrodible firefighting centrifugal pump of a normal pressure Johstadt NP 3000;
  • priming system;
  • pump for foam agent supply;
  • compressor;
  • automatic electronic injector system of compressed air and foam dosing;
  • ejector system of foam agent supply and dosing with manual operation (optional);
  • pipe lines and locking devices;
  • control panel with illumination.
