High speed pump

Condition analysis:


Neutral medium high viscosity industry: tool steel shell, tool steel gear, composite seal

High viscosity weak acid and alkali industry: 9cr18 shell, 9cr18 gear, compound seal

High viscosity and strong acid-base industry: Stellite housing, Stellite gear, perfluoroether mechanical seal

Neutral medium low viscosity industry: housing 304SS, shaft and gear 2205, stainless steel (NSK or SKF) 440 bearing

Strong acid industry: defoamer, hydrogen peroxide, lactic acid, curing agent, acid solution, coating machine adhesive, desulfurizer; nitric acid, hydrofluoric acid, choose 316L or 2205 pump body, 2205 gear, PEEK bushing;

Food industry: for purification, Chinese medicine extract, yeast, honey, syrup and other high hygiene grades, preferred 316SS, shaft and gear 2205, zirconia ceramic bearing

The motor ratio is selected according to the displacement and the viscosity of the medium.


Function introduction Function introduction

The gear metering pump is a pair of gears that mesh with each other, one of which is the driving gear, and the other is the passive gear, which is driven by the driving gear to rotate. There is a small gap in the housing. When the gear rotates, the enclosed volume between the teeth increases in the suction chamber where the gear teeth gradually disengage, forming a partial vacuum. The liquid is sucked into the suction chamber under the effect of pressure difference. As the gear rotates, the liquid is pushed forward by the gear between the gear and the housing in two ways, and is sent to the liquid discharge chamber. In the liquid discharge chamber, the two gears are gradually meshed, the volume is reduced, and the liquid between the gears is squeezed to the liquid discharge port. Each time the gear rotates one time, the volume of the discharged liquid is constant. By measuring the rotation speed of the gear metering pump, the flow rate of the gear metering pump is obtained.
