Product catalog summary
Description and Use
Water pressure systems, also known as autoclaves, are extensively used in the nautical sector to ensure adequate and consistent water pressure for on-board services such as showers, kitchens, sinks, and toilets. For optimal operation, it is recommended to install a non-return valve in the suction inlet and to check the internal pressure of the tank after long periods of inactivity to ensure it is equal to or lower than 0.2 bar of the minimum pressure switch setting.
Composition of the Water Pressure System
The systems are typically equipped with an electric pump (J-mini, J-INOX, MG-INOX, or JBR series), a 20-liter cylindrical tank made of stainless steel or painted steel with a butyl rubber diaphragm suitable for foodstuff, a pressure switch (adjustable from 1.4 to 2.8 bar), a pressure gauge, a 5-way brass pipe fitting, and a 500mm flexible pipe.
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 the JBR series), and a maximum static pressure of 6 bar inside the pump body.
Accessories on Request
Optional accessories include a non-return valve (1” or 1”1/2) and a safety manual resetting pressure switch “SQUARE D” which stops the system when no water is available, preventing dry running.
Performance Specifications
The document provides detailed performance specifications for various models, including voltage, power, absorption, RPM, switch setting, tank pressure, maximum delivery, and maximum head. For example, the J-mini/20X model with stainless steel tank operates at 12V with a power of 0.4 HP, delivering up to 55 liters per minute with a maximum head of 2.8 meters.
Dimensions and Weights
Dimensions and weights are provided for different models, with measurements in millimeters. For instance, the J-mini/20X model has dimensions of 440mm (A) x 295mm (D) x 70mm (E) and weighs approximately 15 kg.

GRUPPI DI PRESSIONE (AUTOCLAVI) WATER PRESSURE SYSTEMS Gruppi di pressione, (autoclavi), largamente utilizzati nel settore nautico per garantire una adeguata e costante pressione idrica nei servizi di bordo quali: docce, cucine, lavandini, wc, ecc. Per un perfetto funzionamento si consiglia: • Installazione di una valvola di non ritorno nel tubo di aspirazione. • Dopo un lungo periodo di non utilizzo dell’autoclave, accertarsi che la pressione interna del serbatoio sia uguale, (o inferiore di 0,2 bar), alla pressione minima di taratura del pressostato. Water pressure systems, widely used in the nautical sector to grant a suitable and constant water pressure for all on-board appliances such as: showers, washbasins, toilets, etc. For a proper operation it is recommended : • To install a non-return valve fitted in the suction inlet. • If the unit is not used for a long time, before operating it, make sure that the inside pressure of the tank is equal to (or lower than 0.2 bar) the minimum setting pressure of the pressure switch. COMPOSIZIONE DEL GRUPPO DI PRESSIONE COMPOSITION OF THE WATER PRESSURE SYSTEM I nostri gruppi di pressione, (autoclavi), sono normalmente forniti equipaggiati da: • Elettropompa serie J-mini, J-INOX, serie MG-INOX o serie JBR (voltaggio e prestazioni specificate in tabella). • Serbatoio cilindrico da 20 litri in acciaio inox (20X) o da 20 litri in lamiera di acciaio verniciato con flangia inox (20L), con membrana interna in gomma butile per uso alimentare. • Pressostato, (taratura di serie 1,4-2,8 regolabile ai valori consigliati in tabella). • Manometro. • Raccordo 5 vie in ottone. • Tubo flessibile da 500 mm. Our water pressure systems are normally equipped with: • Electric pump series J-mini, J-INOX, MG-INOX or JBR (voltage and performances as shown in the table). • Cylindrical tank 20 liters made in stainless steel (20X) or 20 liters made in painted steel sheet with flange made in s.s. (20L), with inside butyl rubber diaphragm suitable for foodstuff. • Pressure switch, (serial setting 1.4 - 2.8 adjustable to the values suggested in the table). • Pressure gauge. • 5-ways pipe fitting made of brass. • Flexible pipe - 500mm. Liquido esente da impurità solide Temperatura del liquido: da +0 a +50 °C.(+70 °C per serie JBR) Pressione statica nel corpo pompa: 6 bar max. Liquid free of solid impurities Temperature range of the liquid: from +0 to +50 °C Static pressure inside the pump body: 6 bar max. Valvola di non ritorno da 1” o da 1”1/2: Pressostato di sicurezza a riarmo manuale “SQUARE D””: Il vantaggio di questo dispositivo rispetto al normale pressostato consiste nel fermare automaticamente l’ autoclave all‘esaurimento della riserva d’acqua, prevenendo la marcia a secco. Non return valve 1” or 1”1/2. Safety manual resetting pressure switch “SQUARE D”: The advantage of this system respect the normal pressure switch is that the water pressure system is stopped when no more water is available, thus preventing the unit to work without water.
