Product catalog summary
Description and Use
The document describes horizontal double water pressure systems composed of two self-priming electric pumps. These pumps are available in stainless steel (J-INOX or MG-INOX) for fresh water or bronze (JBR) for both fresh and sea water. They are widely used on marine vessels to ensure adequate and constant water pressure for onboard services such as showers, kitchens, washbasins, and toilets. The systems can operate with both pumps simultaneously or individually, offering higher water flow compared to traditional systems. It is recommended to pair the system with a water tank for optimal performance.
Components of the Double Water Pressure System
The system includes two self-priming pumps (J-INOX, MG-INOX, or JBR), four ball valves (two for inlet and two for outlet), two non-return valves for inlet, two manual restarting pressure switches, one pressure gauge, stainless steel manifolds, and an "Omega" base with anti-vibration mounts.
Scope and Limitations
The system is designed for liquids free of solid impurities, with a temperature range from 0 to 50°C (up to 70°C for the GD-JBR series). The maximum static pressure inside the pump body is 6 bar.
Accessories on Request
Optional accessories include cylindrical tanks made of painted or stainless steel with capacities ranging from 20 to 500 liters, and a pressure reducer.
Performance Specifications
The document provides detailed performance specifications for various models, including power, absorption, RPM, maximum delivery, and maximum pressure. Models are available in different materials and voltage configurations, including direct current (24V), single-phase alternating current (230M), and three-phase alternating current (230-400T).
Dimensions and Weights
The document includes dimensions and weights for different models, with the option to modify the arrangement upon request. Measurements are provided in millimeters, and weights are listed in kilograms.

Gruppi di pressione doppi orizzontali / Horizontal double water pressure systems Gruppi di pressione composti da 2 elettropompe autoadescanti in acciaio inox tipo J-INOX o MG-INOX (idonee per acqua dolce) o in bronzo tipo JBR ( idonee per acqua dolce e acqua di mare) largamente utilizzati sulle imbarcazioni per garantire una adeguata e costante pressione idrica nei servizi di bordo quali: docce, cucine, lavandini, wc, ecc. 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. L’ utilizzo dei nostri gruppi di pressione serie GD-J, GD-MG e GD-JBR garantisce una maggiore portata di acqua rispetto a quelli tradizionali in quanto le due elettropompe, siano esse entrambe in corrente continua, in corrente alternata o a tensione mista (c.c + c.a.) possono lavorare sia contemporaneamente che singolarmente. Per un corretto funzionamento si consiglia di abbinare un serbatoio di accumulo al gruppo di pressione. 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.
