2K Progressive Cavity Pumps
Liquid metering, dispensing solution
Output without impulse; continuous feeding; steady metering; 
Suitable for highly viscous glue with particles, resistant to wearing; 
Reverse suction design to eliminate dripping and stringing; 
Quick dismount mechanism design for easy cleaning, installation and maintenance! 
Worm-screw trace-amount dispensing valve is driven by the rotor of motor and forms a fixed geometry with the rotor and stator, thus realizing fixed fluid flow metering at constant volume and steady pressure; suitable for applications with glue that contains wearing materials with medium to high viscosity. The two-component system consists of two independent eccentric worm-screw trace-amount dispensing valves for synchronized metering and mixing, and can be combined with an automatic 3-axis robot for mass production.
