External gear pump of fuel dispensers for sale

An external gear pump of fuel dispensers for sale, such as EG1 (https://en.chinaeaglestar.com/products/showproduct.php?lang=en&id=25), EG3 (https://en.chinaeaglestar.com/products/showproduct.php?lang=en&id=15), EG5 (https://en.chinaeaglestar.com/products/showproduct.php?lang=en&id=16), EG6 (https://en.chinaeaglestar.com/products/showproduct.php?lang=en&id=22) and EG7 (https://en.chinaeaglestar.com/products/showproduct.php?lang=en&id=18), consists of two identical, interlocking gears supported by separate shafts. Generally, one gear is driven by a motor and this drives the other gear (the idler). In some cases, both shafts may be driven by motors. The shafts are supported by bearings on each side of the casing.

 

As the gears come out of mesh on the inlet side of the fuel dispenser pump, they create an expanded volume. Liquid flows into the cavities and is trapped by the gear teeth as the gears continue to rotate against the pump casing.

 

The trapped fluid is moved from the inlet to the discharge around the casing.

 

As the teeth of the gears become interlocked on the discharge side of the fuel dispenser pump, the volume is reduced and the fluid is forced out under pressure.

 

No fluid is transferred back through the centre between the gears, because they are interlocked. Close tolerances between the gears and the casing allow the fuel dispenser pump to develop suction at the inlet and prevent fluid from leaking back from the discharge side (although leakage is more likely with low viscosity liquids).

 

The external gear pump of fuel dispensers for sale designs can utilise spur, helical or herringbone gears.
