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.
Our double pressure group have a standard fitting of :
