About this file
This is a submittal data document for a solar-powered submersible pump system (Model 3 SQF-3, Reference Number 95027333) designed for water production applications.
The system is sized for Helena, Montana (latitude 46.5889°N, longitude -112.0385°W) to produce 700 US gallons per day with a peak flow requirement. Key specifications include: a total annual water production of 909 cubic meters (658 US GPD average daily production), solar array configuration of 2 modules in series rated at 0.43 kW and 76 volts with fixed mounting at a 47-degree tilt angle, and a submersible pump rated at 2.3 US GPM at 333.4 feet total head under typical solar radiation conditions of 800 W/m². The pump materials are stainless steel (DIN W.-Nr. 1.4301, AISI 304) for the pump housing, impeller (EN 1.4301), motor, rotor, and stator with EPDM seals. The system includes 82 feet of 14 AWG pump cable with 2.9 percent cable loss and 320 feet of polyethylene riser pipe with total friction losses of 3.448 feet. The dimensional drawing indicates an overall length of 48 5/8 inches with an 8mm (5/16-inch) port connection and 1-inch NPT discharge. AC backup power requirements are 0.656 HP minimum output, producing 2.73 US GPM at 115V or 2.75 US GPM at 230V. Monthly water production varies from 192 US GPD in December to 993 US GPD in July, with the system achieving an average water production rate of 5.8 liters per watt per day.
