HORIZONTAL DOUBLE WATER PRESSURE SYSTEMS

Product catalog summary
Description and Use
The document describes horizontal double water pressure systems, specifically the GD-J, GD-MG, and GD-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, offering higher water flow than traditional systems. A water tank is recommended for optimal operation.
Composition of the Double Pressure Systems
The systems are equipped with 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 antivibration features.
Scope
The systems are designed for liquids free of solid impurities, with a temperature range of 0 to 50°C (up to 70°C for GD-JBR series) and a maximum static pressure of 6 bar inside the pump body.
Accessories on Request
Optional accessories include cylindrical tanks made of painted or stainless steel with capacities ranging from 20 to 500 liters, and pressure reducers.
Performances
The document provides detailed specifications for various models, including material, power, absorption, RPM, maximum delivery, and pressure. For example, the GD-J/1 model uses stainless steel, operates at 24V, and delivers up to 50 liters per minute at a maximum pressure of 3.8 bar.
Dimensions and Weights
Dimensions and weights for the GD-J, GD-MG, and GD-JBR models are provided, with the option to modify arrangements upon request. Measurements are given in millimeters, and weights range from 26 to 85 kg depending on the model.

HORIZONTAL DOUBLE WATER PRESSURE SYSTEMS-1

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.
