DESCRIPTION AND USE
Water pressure systems composed of 2 self-priming electric pumps made of stainless steel type J-INOX or MG-INOX ( suitable for fresh water), or 2 self priming electric pumps made in bronze type JBR (suitable for fresh water an sea water), widely used in the marine field to grant a proper and constant water pressure for all on board appliances such as: showers, kitchen, washbasins, toilets, etc.
The use of our double pressure systems series GD-J, GD-MG and GD-JBR allows for a higher water flow than the traditional pressure systems, as the two pumps made in d.c., a.c., or mixed (d.c + a.c) can work either simultaneously or singularly.
For a proper operation of the group it is recommended to install a water tank.
COMPOSITION OF THE DOUBLE PRESSURE SYSTEMS
Our double pressure group have a standard fitting of:
No. 02 Self priming pumps type “J-INOX” , “MG-INOX” or “JBR” (voltages and performances as shown in the table)
No. 04 Ball valves (No. 02 in the inlet, No. 02 in the outlet)
No. 02 Non return valves in the inlet
No. 02 Manual restarting pressure switch.
No. 01 Pressure gauge.
Manifolds made in stainless steel
“Omega” base made in stainless steel with antivibration.
SCOPE
Liquid free of solid impurities
Temperature range of the liquid: from +0 to +50 °C ( + 70°C for series GD-JBR)
