High Speed Pump: principles, applications and advantages
2. Working Principle
The gear metering pump is a pair of intermeshing gears, one of which is a driving gear and the other is a driven gear that is driven to rotate by the driving gear. The housing has a small gap. When the gear rotates, in the liquid suction chamber where the gear teeth gradually disengage, the sealed volume between the teeth increases, forming a partial vacuum, and the liquid is sucked into the liquid suction chamber under the pressure difference. The gear rotates, and the liquid is driven by the gear between the gear and the casing to be sent to the discharge chamber. In the discharge chamber, the two gears gradually mesh, the volume is reduced, and the liquid between the gears is squeezed to the liquid discharge port. Each time the gear rotates, the volume of the discharged liquid is constant, and the flow rate of the gear metering pump is obtained by measuring the rotation speed of the gear metering pump.

3. Key Features of High Speed Pump
- Precision Casting with Strong Versatility: As a precision-cast general-purpose pump, it offers excellent fluid compatibility and adapts well to a wide range of fluid media.
-
High Metering Accuracy: Equipped with a unique friction-plate structure on the gear sides, it achieves metering accuracy of up to ±1% under ideal operating conditions, ensuring stable and controllable flow.
-
Dry-Run Resistance and Corrosion Resistance: Built with corrosion-resistant plain bearings (slide bearings), it maintains reliable performance and extended service life even in fluids with poor lubricity.
