Magnetically coupled external gear pumps

The external gear design offers flow that is relatively independent of pressure providing constant fluid delivery with no pulsations. The flow will have a controlled volume that is accurate and repeatable, making it highly suitable for metering applications. The D, T, & P Series pumps can meet these demands in circumstances with high differential pressures and high system pressures, as well as thin to moderate viscosity fluids. The high volumetric efficiency is achieved by utilizing two identical gears that rotate against each other.

• One gear is driven by being coupled with the magnet. The other gear, the driven gear, rotates in the opposite direction. The un-meshing of the gears creates a vacuum on the inlet side, pulling media into the pump
• The media flows around the gears and housing to the discharge side
• The gears mesh back together forcing the media out the discharge end precisely into your application

Advantages:

• Long Life – Up to 20,000 Hours
• Metering Accuracy Better Than 1%
• Continuous Fixed Displacement Flow
• Virtually No Pulsation
• Easy, Low Cost Installation and Start Up
