(1) Teflon composite diaphragm: has a patented structural design, the use of finite element analysis of the fatigue resistance characteristics of the diaphragm, thereby greatly extending the service life of the diaphragm, and there is no problem of oil mist pollution. Rubber surface using a special process compound PTFE coating (thickness ≤ 0.2mm), greatly improving the corrosion resistance of the pump, can resist most of the corrosive media (including strong acids, strong alkalis); compared with the traditional diaphragm, in airtightness, corrosion resistance and strength is a chip higher.
(2) EPDM rubber diaphragm: the use of a unique structural design, compared to the composite diaphragm, lower noise, low cost, EPDM withstand relatively small tension. In the non-strong corrosive environment, the service life is slightly higher than the composite diaphragm. Excellent performance in weak acid and weak alkali environment, economical and applicable, can be preferred.
Main features and advantages
1） Small volume, low noise, low vibration, maintenance-free.
2) 24-hour continuous operation and long service life.
3) Non-polluting to the medium, providing pure liquid transmission.
4) allows pumping of almost all chemical reagents.
5) good sealing, good chemical stability and corrosion resistance.
6) Self-priming liquid pump, no need to add "priming water" to work, real self-priming function.
7) Easy installation, can be installed on the bottom and side in both directions.
Rubber valve features
Special structure design with special pump head, to ensure sufficient flow while limiting the vibration amplitude of the valve, and the vibration part of the valve is only subject to the pressure from the medium, which can greatly improve the service life of the valve.
Pump head features
Pump head material: the choice of imported PP, can be resistant to weak acid, weak alkali corrosion, the biggest advantage is no pollution of the medium, can provide pure liquid transmission; can also choose imported PPS, the advantage is high strength, corrosion resistance better than PP, the disadvantage is that the purity of the medium is not as good as PP.
Eccentric wheel assembly features
Eccentric wheel material selection SUS304 food-grade stainless steel, to prevent any pollution of the environment; structural design using motion simulation analysis, to achieve accurate counterweight; the use of high-precision imported bearings to ensure that in the state of high-speed operation, but still maintain excellent performance, greatly reducing the vibration and noise of the pump;.
Micro DC motor features
Independently newly developed miniature DC motor with small energy consumption and large starting torque, which can realize starting with load.
