DC Powered Pumps

DC Powered Pumps use direct current from motor or solar power to move fluid in a variety of ways. Motorized pumps operate on 6, 12, 24, or 32 volts of DC power and use hand-operated, electric, pneumatic, or hydraulic motors. Solar-powered DC pumps use photovoltaic (PV) panels with solar cells that produce direct current when exposed to sunlight.

Many DC powered pumps use centrifugal force or positive displacement to move fluids. Centrifugal pumps apply centrifugal force to generate velocity, use rotating impellers to increase velocity, and push fluids through an outlet valve. Positive displacement pumps use rollers, gears, or impellers to move fluid into a fixed cavity so that when liquid exists, the vacuum that is created draws in more fluid. Diaphragm pumps are the most commonly used positive displacement pumps. They include a single diaphragm and chamber, as well as suction and discharge check valves to prevent backflow.A variety of special DC powered pumps are available.

Drum pumps are designed to transport or dispense the contents of drums, pails, or tanks. Macerator pumps empty holding tanks for sewage and typically include a bronze cutter to grind waste down to a small particle size. Sump pumps fit in compartments and remove unwanted water build-up that threatens to encroach on living or equipment space. Bilge or ballast pumps are used onboard boats and ships to remove water from the bilge or to lower or remove water for ballast. Micro pumps use a flexible structure to help move fluids in miniaturized systems and circulation pumps keep media circulating through distribution or process systems. Sampling pumps remove small amounts of media for analysis. Magnetic drive pumps use a magnetic or electromagnetic drive and are suited for laboratory, production line, chemical processing, general transfer utility, and original equipment manufacturer applications. DC powered pumps are available with a variety of specifications and features. Devices vary in terms of maximum discharge flow, minimum discharge pressure, inlet size, and discharge size. Adjustable speed pumps can operate at speeds selected by an operator while continuous duty pumps maintain performance specifications at 100% duty cycle.

Run dry pumps can operate without pumped fluid or external lubrication for an extended period of time. Some DC powered pumps are corrosion-resistant, explosion-proof, or meet strict guidelines established for sanitary process applications. Others are configured to pump sticky or stringy materials, include an integral grinding mechanism, or have centerline suction or discharge.

DC powered pumps can move media either vertically or horizontally, depending on the direction of the pump stator / rotar assembly. Level control devices turn pumps on and off automatically, depending on the level of the media.DC powered pumps are used in a variety of general industrial and commercial applications, as well as in the aerospace, automotive, food service, and medical industries. DC powered pumps are used to move liquids such as acids, chemicals, lubricants and oil, as well as water, wastewater, and potable water. Some devices move combustible or corrosive fluids, while others transport non-liquid gas or air media.
