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...

Who Took Our Poll?Top
From our perspective, we believe Switched Reluctance will be the eventual motor driver, materials cost will drive the the products in this direction.
Brushless heavy duty 12 Volt DC motors as replacement to Brushtype motors.
Brushless technology, robust plastic housing, sealed ball bearing
Two brands: piusi and fillrite.
Applications and UseTop
Carefully select the correct product when pumping flammables or a disaster can occur.
Unit cost is a factor, however it should not be the overriding factor, maintenance is overlooked too often.
Oversize rather than undersize; use gate on output to control load on motor; pump materials should fit the materials being pumped.
Most vulnerable part is motor starter, not the hydraulics body. Need to consider both electric and hydraulic circuits with same importance.
Know what type of pump you are getting. Depending on what your application is, certain types of pumps will not work. For example, a centrifugal pump may be a bad choice if you are pumping a viscous fluid against a pressure.
Electrical apparatus or control products do not handle current ratings for hazardous locations.
