Product catalog summary
Description and Use
The document describes vertical double water pressure systems, specifically the GDV-J, GDV-MG, and GDV-JBR series. These systems consist of two self-priming electric pumps made from stainless steel or bronze, suitable for fresh and sea water. They are used on marine vessels to maintain consistent water pressure for onboard services like showers and kitchens. The systems can operate with both pumps simultaneously or individually, and it is recommended to pair them with a water tank for optimal performance.

Composition of the Double Water Pressure System
The system includes two self-priming pumps, four ball valves, two non-return valves, two manual restarting pressure switches, a pressure gauge, stainless steel manifolds, and an Omega base with anti-vibration mounts.

Scope and Limitations
The systems are designed for liquids free of solid impurities, with a temperature range from 0 to 50°C (up to 70°C for GDV-JBR series) and a maximum static pressure of 6 bar inside the pump body.

Accessories on Request
Optional accessories include cylindrical tanks with capacities from 20 to 500 liters and pressure reducers.

Performance Specifications
The document provides detailed performance specifications for various models, including power, absorption, RPM, maximum delivery, and pressure. Models are available in different materials and voltage configurations, including direct current and single or three-phase alternating current.

Dimensions and Weights
Dimensions and weights for the GDV-J, GDV-MG, and GDV-JBR models are provided, with the option to modify arrangements upon request. Measurements are given in millimeters, and weights are specified in kilograms.

GDV-J • GDV-MG • GDV-JBR Gruppi di pressione doppi verticali / Vertical Double Water Pressure Systems GDV-J GDV-MG 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 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. L’utilizzo dei nostri gruppi di pressione serie GDV-J, GDV-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 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.
