dipompa

Dipompa is a term used in Italian technical literature to denote a dual-pump arrangement in a single pumping system. Depending on configuration, a dipompa can deliver higher flow when pumps operate in parallel, or greater head when arranged in series. English-language references usually translate it as dual-pump or two-pump system.

A dipompa typically comprises two pumps connected to common suction and discharge headers, with valves and instrumentation to coordinate operation. In parallel, pumps share the load to increase flow; in series, the pumps raise the system pressure. Some installations employ redundant or hot-standby layouts for reliability.

Control and protection are provided by a pump controller or PLC that monitors pressure, flow, and motor current, and performs sequencing to prevent dry running and to balance loads. Common protections include overload, cavitation alarms, thermal protection, and check-valve arrangements to prevent backflow during shutdowns.

Applications include municipal water supply, irrigation, chemical processing, and fire-protection networks where reliability and flexibility are important. Advantages of dipompa systems are higher availability, fault tolerance, and maintenance options; disadvantages include increased cost, complexity, and energy management challenges if pumps are not well matched.

Etymology: the term derives from Italian di- meaning "two" and pompa meaning "pump." In practice, the concept is widely described in English as dual-pump or two-pump systems.
