DC powered pumps use direct current from motor, battery, or solar power to move fluid in a variety of ways. Motorized pumps typically operate on 6, 12, 24, or 32 volts of DC power. Solar-powered DC pumps use photovoltaic (PV) panels with solar cells that produce direct current when exposed to sunlight.

 

DC vs. AC

The main advantage of DC (direct current) pumps over AC (alternating current) pumps is that they can operate directly from a battery, making them more convenient and portable. They are easier to operate and control, since AC systems typically require a controller to manage speed. DC pumps also tend to be more efficient. However, AC pumps usually are designed for higher speeds and larger bursts of power. They also have a longer working lifespan than DC pumps.

Types

DC pumps come in many different design types, each with its own method of operation, advantages, and preferred applications. For more information on these different types of pumps, visit the Pump Types information page on GlobalSpec.

  

Specifications

As with most pumps, the primary specifications to consider when discerning DC powered pump performance are flowrate, pump head, pressure, horsepower, and operating temperature. For an explanation of these specifications and pump performance curves, visit the Pump Flow information page on GlobalSpec.

 

Features

DC powered pumps can also be distinguished based on the features they provide, such as adjustable speed, run-dry capability, and corrosion resistance. GlobalSpec's Pump Features page provides a full list and explanation of these different pump features.

  • Booster Pumps

    Booster pumps are used in applications where the normal system pressure is low and needs to be increased.

  • Condensate Pumps

    Condensate pumps are used to collect and transport condensate back into a steam system for reheating and reuse, or to remove unwanted condensate from an HVAC or appliance collection pan.

  • Diaphragm Pumps

    Diaphragm pumps use a diaphragm that moves back and forth to transport liquids from one place to another.

  • Drum Pumps

    Drum pumps are used to transfer materials from a container into a process or other container. They may be electrically, hydraulically, or pneumatically powered depending on the working environment or application.

  • Gear Pumps

    Gear pumps use intermeshing gears to pump various types of liquids. Typically, one gear is the driver and the other is free wheeling. The gears have very tight tolerances so that the fluid being pumped cannot pass through them. Common uses for gear pumps include high pressure, metering, and flow control applications.

  • Metering Pumps

    Metering pumps are positive displacement pumps designed to dispense precise amounts of fluids and measured flow control.

  • Screw Pumps

    Screw pumps are rotary, positive displacement pumps that have one or more screws to transfer fluids or materials along an axis.
