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.
