High precision liquid metering stainless steel pumps gear mini hot melt glue pump


The dosing gear pump is composed of a pair of meshing gear.One of them is diving gear and the other is driven gear,The housing leaves a small gap, and when the gear rotates, the tooth is gradually disengaged from the meshing cavity.

The volume of the seal between the teeth increases, forming a partial vacuum, and the liquid is sucked into the suction chamber under the pressure difference,Every time the gear rotates, the volume of the liquid to be removed is constant, and the speed is controlled.Thereby calculating the flow of the gear metering pump...



The dosing gear pump with high accuracy,no pulsation;unique design,the  the flexible drive connection between the motor and the metering pump eliminates the influence of the alignment error between the motor and the metering pump on the measurement accuracy, and also prevents the motor from transmitting the vibration to the dosing gear pump.

  • High accuracy dosing and semi-automatic control 
  • More material for the more medium 
  • More sealing methods and good sealing performance
  • Wide measurable range, minimum displacement 0.05cc
  • High measurable medium viscosity, wide temperature range.
