DESCRIPTION AND USE

Water pressure system 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 GDV-J, GDV-MG and GDV-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 WATER PRESSURE SYSTEM

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 with antivibration

SCOPE

• Liquid free of solid impurities
  
• Temperature range of the liquid: from +0 to +50 °C (+ 70°C for series GDV-JBR)
  
• Static pressure inside the pump body: 6 bar max

ACCESSORIES ON REQUEST
