1. The high—strength acid and alkali resistant stainless steel rotating shaft design is adopted to ensure the stable and accurate operation of the core part rotor in the working chamber; The rotating shaft with ultra— high strength and stiffness plays an obvious role in eliminating vibration and improving the service life of mechanical seal; 2. Products writh various working clearances can be selected according to different process requirements to meet the pressure needs under different working conditions, and the maximum output pressure can reach 16bar; 3. There is no special fixing device for the pump body, which will not affect the position of mechanical seal and other fixed parts during disassembly and maintenance; 4. The mechanical seal structure design of wave plate spring is adopted to make the force on the sealing surface more uniform and make the installation diagram 03 http.//wwvv.jonhen.net service life of the seal longer; The interchangeability of rotors of various shapes 5. can be realized on the same equipment; 6. All materials in contact with materials are acid and alkali resistant stainless steel, which fully meets the requirements of food safety and hygiene standards and GMP, and can fully meet the cleaning needs of CIP: Synchronous gears and bearings manufactured 7. with high precision; 8. Various forms of power transmission mechanism.
