Solar Equipment Applications For Our Pumps

Magnetic drive pumps are a critical element for the operation of solar equipment, such as thermal heating systems and alternative energy applications. Pumps for solar equipment such as our Brush 12V and 24V 809,809-HS, and 893 DC Mag are prefect for such applications. With these brush type motors, the solar pump will not suffer damage if the starting voltage is below what the pump is rated for. The speed of these pumps, and consequently the flow and head, can be altered by changing the incoming voltage.

Engineered to withstand harsh conditions, certain March mag drive solar pumps can be used submerged and are capable of a maximum flow of 8 gallons per minute at 1 foot and have a maximum head of 15.5 feet.

Can the Sun be Used to Power Water Pumps?

Solar power is more affordable and prevalent than ever before. Since 2008, U.S. installations have grown seventeen-fold from 1.2 gigawatts (GW) to an estimated 30 GW today. This is enough capacity to power the equivalent of 5.7 million average American homes. Solar power is a popular way to power water pumps, especially a solar pump in a remote location such as irrigation systems, ponds, fountains, water wells, and for livestock ponds where electricity is not readily available. If water is only needed during sunny conditions, the system will work without a battery backup system. However, if the pump is needed during overcast days or evenings and nights, then a battery system is necessary. Pumps for solar systems are efficient and practical for many uses.

Are Solar-Powered Water Pumps Economical and Practical?

Pumps for solar systems are both practical and economical. They are an extremely efficient way to provide a water pump where electricity is not readily available. They produce best when the weather is sunny, but with the use of a backup system, a solar pump provides water in all conditions.

For drawing water up short distances, 10 to 20 feet, a surface pump is practical. When the well is deep or water must be drawn for longer distances, a submersible pump is preferred. March centrifugal mag drive pumps are designed to pump water or chemicals and can withstand the harsh conditions required for some pumps for solar systems.

What are the Limitations of Solar Water Pumps?

The limitations of pumps for solar systems depends primarily on the selected pump and solar system output. March mag drive pumps used most often with solar systems are capable of a maximum flow of up to 8 gallons per minute at 1 foot and have a maximum head of 15.5 feet. Different solar pumps have differing limitations and requirements. Solar pump systems are limited by:

• Available sunshine and daylight hours
• Vertical and horizontal distance water is to be pumped
• Water flow decreases greatly when weather is cloudy or overcast unless backup power is supplied

When you need a small water pump, up to 8 gallons a minute, a solar pump can be an excellent solution. All costs are upfront in the purchase of the pump and solar system. There are no additional costs other than occasional maintenance.
