The pump will have a minimum current draw when stalled and no pumping is taking place. However, the current output (amps) will be directly proportional to sun intensity. It will also avoid trying to operate the pump in a stalled condition when solar output is too low.Įach residential-size solar module will produce a fairly constant 17-volts output at almost any level of sunlight. Although it is possible to connect the pump leads directly to the output terminals of the solar module, a controller provides much better pump performance and start/stop control. Your solar powered pumping system should include a pump controller such as the one in the photo on page 37. For most applications the tilt will be equal to your latitude. Most farm and ranch applications should have the modules and pump controller mounted on a raised pole to stay above snow drifts and potential damage from animals.Ī 24-volt DC SolarJack pump for a 4-inch well casingĪ pole mount also allows easier adjustment of module tilt and east-west orientation during initial setup to achieve the best overall year-round performance. This low flow rate can still provide over 350 gallons of water per day from all but the deepest well applications.Ī solar module can be mounted almost anywhere, but should face in a southerly direction (for North America). Unfortunately, this also usually means a very low flow rate, so having a storage tank or open trough is essential.Īlthough the flow rate can be less than one gallon per minute (GPM) for the smaller pump sizes, this small flow will be fairly constant throughout the solar day (9 AM to 3 PM for most locations). A DC water pump is designed to pump using the absolute minimum of electrical power. Low voltage DC pumps designed to operate on solar power are not designed like 220-volt AC water pumps. Local residents enjoying the “solar water supply” at the open top drinking tank.īy adding a storage tank and increasing the size of the pumping system, excess pumped water can be stored, which can continue to supply water during the night or when it’s cloudy and the pump is off. When the sun is shining, the system is pumping, when the sun is not shining, the system is offsimple. A solar-powered water system is one of the easiest solar power systems to install, since you will not need a battery or battery charging equipment. These solar applications made economic sense because the location was too remote to run a long power line. We have also designed larger systems to pump directly from drilled wells up to elevated storage tanks, which provide gravity-fed water back down to remote ranch buildings. I recently designed a solar-powered pumping system for a local farmer wanting to pump water from a lake up to a watering trough for cattle in a distant fenced field. There are many remote applications where a solar-powered water pump is more cost effective than installing a conventional grid-connected AC pump. In this issue I will address another form of “free” water pumping.

BELOW GROUND CANTEX LIFT STATION AS BUILT DRAWING ISO
Hydromatic, an ISO 9001 registered quality system, is a part of the Pentair Pump Group of Pentair, Inc. Hydromatic is a manufacturer of wastewater products for residential, commercial, municipal, domestic and international markets. Hydromatic, founded in 1959, is located in Ashland, Ohio, with additional distribution in Canada. To complement the standard features, a variety of options are available for the station and controls. To regulate the temperature a thermostat controlled vent fan is furnished in the station. Piping includes individual suction lines terminating at the 90˚ suction elbow, individual discharge swing check valves, a three-way plug valve, and individual air bleed lines with shut off valves. The pumps are complete with an open drip proof “T” frame motors up to 25 HP with flows from 70 to 600 GPM. The station will accommodate two 4˝, V-belt driven self-primer pumps. The new station comes complete with four access panels, two lockable-hinged doors and two solid fastened panels with tamper-proof screws, providing easy access for routine maintenance. For an added security, the PFC6X6 station is designed to be vandal-resistant.
