DC voltage: 12VDC
Pump load: 15 volts, 19.3 amps, 290 watts
Min PW watts: 377
Applications include irrigation, live stock, domestic water, pond management, water treatment, solar water heating, hydronic space heating, hot water circulation, and fire protection. They can tolerate silty water and deliver up to 70 GPM.
The temperature limit for the standard pumps listed here is 140°F (60°C). The SunCentric pumps are also available in High Temperature models, which raise the temperature limit to 240°F (115 °C). The High Temperature versions have a brass impeller which reduces flow by about 15% using the same watt-age.
These centrifugal pumps have been in worldwide use since 1989. They can be used PV array direct without batteries and do not require a pump controller or linear current booster (LCB). Maximum suction lift is 10 vertical feet (3 m). Use a foot valve if the pump is mounted higher than the water source.
No routine maintenance is required. These pumps can be repaired in the field using ordinary tools and skills, without removing the pipes. They feature a cast iron pump body with polycarbonate impeller. The included instruction manual shows illustrated repair details. For best reliability, minimize or eliminate suction lift by placing the pump low and close to the water source, minimizing the possibility of cavitation which causes excessive wear and loss of performance.
