This rotary vane pressure pump uses one-third to one-half the energy of conventional AC pressure pumps and eliminates the high starting surges that can push inverters to their limits.
The Flowlight Model 2930-48 is available in 48 volts DC only. It is designed for use with battery banks and is not intended for direct solar operation.
At 16.5" long, these pumps are more powerful, quieter, and significantly more durable than less expensive Shurflo diaphragm pumps. Wearing parts are replaceable and typically last 5 to 10 years, while the overall life expectancy of the pump is approximately 15 to 20 years.
Flowlight pumps are an excellent choice for pressurizing a full-time off-grid residence. A large pressure tank, 40 gallons minimum, must be used and can typically be purchased locally.
We also recommend installing the pump in an outdoor pump house with the pressure tank, as the rotary vane action may be too noisy for some indoor applications.
The EZFLOW Installation Kit and Inline Filter Kit are considered essential equipment and make the pump easier to install and service.
The EZFLOW Installation Kit includes:
The Dry Run Switch helps prevent pump damage if the water source runs dry. This is essential protection where water shortages are possible, as operating the pump without water can permanently damage it.
Do not allow this pump to run dry.
The Dry Run Switch may be added at any time.
