DC Powered Pumps
What is a DC Powered Pump?
A type of pump that uses direct current charge to power the motor. They're useful for many purposes, particularly in rural locations that are far from power sources. Like gas-fueled pumps, they don't have to be connected to an electric grid. But they also offer advantages that many gas-fueled pumps don't have -- they're safer, they tend to last longer, and they don't have to be regularly refueled. While batteries are the most common power sources, solar power is an increasingly popular source of DC power.
Where are they used?
DC Power may be applied to many different types of pumps that are needed in rural areas — for example, well pumps that draw well water from under ground, sump pumps that are used to prevent basement flooding, or booster pumps that are used to push wastewater to a faraway location.
They're also good for pumps that are only activated intermittently to deal with sudden flooding or high water levels. Using a DC powered pump prevents the user from having to connect the pump to a power source. They're also good for pumping from water sources that are far away from electrical outlets, such as rivers, streams, or natural rural ponds. However, they usually aren't powerful enough to send water long distances.
