Motor kit to change pump to a 48vdc from 24vdc
The Solar Force piston pumps operate directly from a PV array, or from a battery bank charged by PV or any other power source. They can draw water from a shallow well, pond, stream, river or storage tank and can push water up-hill (230' maximum head), through miles of pipeline, or for pressurized water systems (100 psi max; minimum 60 gal. pressure tank required). They can be used for domestic, agricultural, commercial, or industrial applications. Suction capacity is 25' at sea level (subtract 1' for each 1,000' above sea level). 5-9 GPM pumping capacity.
Robust, durable, and reliable, Solar Force pumps use less energy per gallon of water delivered than any other pump that we sell. The pump head is cast iron with a brass cylinder. These pumps have a proven design with a 20-year life, and are simple to maintain with common hand tools. Leather piston seals are easy to replace (5 to 10-year maintenance interval). The well illustrated installation and repair manuals make it easy to install and service.
The DC models are the most efficient, but the AC models use low-surge motors with low starting torque, reducing inverter and wire size requirements. Available with 12, 24, or 48 VDC motors, or with 120 VAC or 230 VAC, 50-60 Hz motors.
Solar Force pumps have 1.5" female-threaded intake ports and 1" female-threaded outlet ports. They measure about 22" x 13" x 16" high, and have a maximum weight of 115 lbs. Shipped in two boxes. 2-year warranty.
The Watt values listed in the following chart represent power used by the pump. For PV array direct operation, the array must be at least 20% larger. Over-sizing the array will increase the amount of water delivered per day because a larger array will produce the pump's required wattage in less light, allowing the pump to run at full speed for more hours each day, or in cloudy weather. For example, a 560 W array will produce 280 W in one half the amount of sunlight present at noon. The extra available power will not damage the pump motor as long as the array voltage doesn't exceed the voltage range of the pump motor.
