Animal Grease High Viscosity Low Flow Gear Metering Pump
Gear Metering Pump is driven by a pair of intermeshing gears, one of which is a driving gear and the other is a passive gear, which is driven by the driving gear to mesh and rotate, and will be a small gap in the cavity of the gear pump.
When the gear rotates, in the suction chamber where the gear teeth gradually disengage, the closed volume between the teeth increases, forming a partial vacuum, and the liquid is sucked into the suction chamber under the action of the pressure difference. It is pushed forward by the gear between it and the casing, and 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.
