Water system pumps are pressure sensor controlled multi-outlet pumps with variable speed drive, serving 1-5 outlets. Electronically controlled motor speed to maintain steady flow. VSD accepts from 10 to 29 volt DC for use with 12 or 24 volt DC power. As flow reduces, amp draw reduces to conserve energy. Self-priming up to 10’. Gives constant flow and hot water mix. Eliminates accumulator tank. Diaphragm design allows for extended dry running. Ignition protection. Fitting: connections for 1/2” ID hose or 1/2” qest threads.
