CB2 COMBIPRESS - Pressure boosting sets - 1

COMBIPRESS "CB2" Pressure boosting sets CB2 - 2CP CB2 - 4CP OPERATING PRINCIPLES CONSTRUCTION CHARACTERISTICS COMBIPRESS are twin pump pressure boosting sets supplied preassembled and ready to install. The sets are designed so that the pumps operate automatically in succession as the demand for water increases. This results in significant energy savings as the second pump only runs at times of high demand. The lead pump is alternated automatically by the control box. • USES • • • Clean water and chemically non-aggressive liquids. Water supply: pressure boosting in industrial applications, condominiums, hotels, communities, water treatment plants, campsites, schools, hospitals, barracks, etc Irrigation: playing fields in general (football, golf, etc), agricultural cultivation, artificial snow systems. • • • PUMPS complete with suction and delivery manifolds, ball valves and non-return valves BASE made from sheet metal PRE-INSTALLED control systems, comprising a pressure gauge and two user-adjustable pressure switches (the factory settings are indicated in the following tables), fitted to the delivery manifold. CONTROL BOX complete with door-interlock power switch, low voltage pressure switch command circuit, automatic pump alternation function, thermal overload protection and pump start-up protection (prevents the pumps from continuously starting-up as a result of small and brief supply demands). CB2m: single-phase 230 V - 50 Hz. CB2: three-phase 230/400 V - 50 Hz up to 4 kW. 400/690 V - 50 Hz from 5.5 to 18.5 kW.
