How Edwards Gear Pumps Work
The Edwards gear pump develops flow by carrying fluid between the teeth of two meshed gears. One gear is driven by the drive shaft and turns the other. The pumping chambers formed between the gear teeth are enclosed by the pump’s housing and the side plates.
A partial vacuum is created at the inlet as the gear teeth unmesh. Fluid flows in to fill the space and is carried around the outside of the gears. As the teeth mesh again at the outlet, the fluid is forced out. High pressure at the pump’s outlet imposes an unbalanced load on the gears and their bearing support structure.
Features & Benefits
- Perfectly timed rotors synchronised by timing gears, making it physically impossible for rotors to clash against each other
- Casing liners minimise corrosion, wear, and tear, extending pump lifespan
- Shafts are supported on both ends by bearings, not bushings, for added reliability
- Pump drive flexibility to suit different operating conditions
- Dry running capability
- Rugged bronze construction – resists corrosion and provides many years of service
- Inexpensive repair and maintenance
- Flexible – adapts to existing or new drive equipment
- Self-priming
