MOTORPUMPS AND FIRE-FIGHTING SYSTEMS – UNI 9490 STANDARDS

“ED SYSTEM”
  • With a main electric pump
  • With a main diesel motor pump
  • With a jockey electric pump

G.M.P. S.p.A. with an experience of more than 30 years in the production of electric and motorpumps, has also obtained an important specialization in fire-fighting systems. With a careful knowledge of standards, GMP can propose suitable and complete pumping systems for fire-fighting.

Considering the different technical performance required, we can study the most convenient solution to obtain the best result and we can prepare any technical information.

A very good fire-fighting system is complete of:

- a main electric pump;

- a pump with same capacity with endothermic motor;

- a jockey pump with electric motor at low power;

- control panel for the two pumps with general switch, starting and stopping remote control switch, thermic protections, selectors for automatic or manual running, warning lights;

- control panel for motor pump with endothermic motor with selectors for automatic or manual running, battery charger, warning lights, system for starting, system for heating of oil.

  

 
 

“EE SYSTEM”

  • With 2 main electric pumps
  • With a jockey electric pump

 

 

“D SYSTEM”
  • With a main diesel motor pump
 
 

Logistic of Running

The jockey electric pump, supplied with an hydraulic air vessel, keeps in pressure and full of water the complete system, and, by a special pressure-switch, starts to provide for little losses of the system.

When more water is required, for the opening of one or more gates, the pressure of the system lowers and, by the pressure-switch, the main electric pump starts.

When the main pumps does not start, for absence of electric power or for a break-down, the further decrease in pressure starts the motorpump by a calibrated pressure-switch.

When no water is required, by the closing of the gates, the pressure of the system increases and stops the pumps.
