Stator and Rotor for Screw Valves
1. The stator core is made of FFKM, FKM, NBR, optional. The stator housing is made of AL 7075 and the surface is fine ground after rotary milling to increase the high surface finish. The surface is fine-milled after cyclone milling to increase the high surface finish. The stator core and stator housing are die-cast to ensure the accuracy of the stator and rotor fit.
2. The material of the drive shaft is SUS304, the surface is fine grinding after CNC lathe machining to increase the high surface finish (0.40). The flexible shaft is wrapped with perfluoroelastomer, which ensures that the screw will not be suffocated with the high speed rotation of the drive rod (the maximum speed can be up to 2.2 revolutions/second).
3. The material of the screw is imported stainless steel, the surface of which is fine ground after cyclone milling and then plated with titanium to increase the high surface finish and wear resistance. Ceramic material is also available.
4. The combination of rotor and stator forms a sealed space, and the motor continuously extrudes glue particles by turning the rotor to form a stable spitting effect.

Product Features and Advantages
High glue dispensing precision
Adopting servo motor drive and eccentric screw rod feeding, so that the glue adhesive can be continuously and stably output.
Wide range of glue viscosities and spitting volumes
Adjustment of motor speed and gas pressure can be used to dispense different glue viscosities and quickly change the amount of glue spit.
No dripping and pulling of glue
The motor reverses and sucks back, easily solving the problem of dripping and pulling of glue.
Great adaptability of stator
The stator is resistant to medium corrosion and has a long service life, which greatly reduces the user's overall cost of ownership.
Volumetric metering
True volumetric conveying, the flow rate is not affected by pressure changes.
High output pressure
Single pump output pressure ≥ 20bar
Application Fields
Automotive, Electronics, Aerospace, Renewable Energy, Food Industry, Pharmaceuticals, Biotechnology, 3D Printing
