Small displacement gear metering pump

The working principle of the gear metering pump, the gear metering pump is through a pair of gears that mesh with each other, one of which is a driving gear and the other is a driven gear, which is driven by the driving gear to mesh and rotate. There is a small gap between the gear and the pump casing. When the gear rotates, in the suction chamber where the gear teeth are gradually disengaged, the enclosed 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. As the gear rotates, the liquid is divided into two ways in the gear. It is pushed forward by gears with the housing and sent to the drain cavity. In the drain cavity, the two gears mesh gradually, the volume decreases, and the liquid between the gears is squeezed to the drain port.

Gear metering pump Widely used in fluid measurement

High precision, in a variety of temperature, high viscosity,  high pressure, good wear resistance conditions, can ensure  a stable and repeatable flow, measurement  accuracy as high as 0.3%.

The liquid is sucked into the suction chamber by a pile of occluded gears under the action of pressure difference, and then the medium is discharged from the chamber with rotation.

Compared with stainless steel tool steel has higher hardness, because it is a passive rotation of hard material, can reduce wear and long service life

one inlet and one outlet. Minimum displacement can be customized0.05cc  The maximum displacement can be customized200~1000cc

The working principle of the gear metering pump, the gear metering p- ump is through a pair of gears that mesh with each other, one of which  is a driving gear and the other is a driven gear, which is driven by the d- riving gear to mesh and rotate.

In the drain cavity, the two gears mesh gradually, the volume d- ecreases, and the liquid between the gears is squeezed to the drain port.

The gear metering pump with high accuracy,no pulsation;unique desi- gn,the the flexible drive connection between the motor and the mete- ring 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 gear metering 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.Advantages: suitable for high viscosity, low speed, high pressure, good wear resista- nce. Disadvantages: not suitable for media containing carbon powder, iron powder,carbon fiber, and quartz sand.Application industry Resin, ink,coating, spinning oil agent,AB glue,textile dye, animal fat, neutral solution,coating machine adhesive,dispensing glue injection sy- stem,hot melt adhesive equipment,Pu gel,oil,coating oil,colorant, pol- yurethane, paraffin, et
