### 1. Diaphragm Pump Overview A diaphragm pump is a type of positive displacement pump that uses a flexible diaphragm to move fluid through the pump chamber. It operates by creating a vacuum on one side of the diaphragm and then forcing it back to push the fluid out. This design allows for precise control over flow and pressure. Known as a Roots pump, lobe pump, or high-concentration pump, it relies on two synchronized rotors that rotate in opposite directions, driven by an external gear system. These rotors divide the chamber into several small spaces, following a specific sequence (I-II-III-IV) to ensure continuous fluid movement. As each chamber fills and closes, the fluid is transported through the pump, maintaining consistent flow and pressure. ### 2. Product Features 1. All parts in contact with the material are made of stainless steel that meets sanitary standards, along with non-toxic rubber seals for safe and hygienic operation. 2. The rotor and pump chamber are designed without dead zones or non-metallic components, preventing contamination of the transported material. 3. Suitable for CIP cleaning and steam sterilization, meeting U.S. FDA and GMP standards. 4. Ideal for transporting viscous materials, foaming liquids, and substances with high solid content, preserving their original quality and preventing chemical reactions. 5. Uses dynamic and static mechanical seals that can be rinsed with water, withstand high pressure, and ensure no leaks. 6. Compact size, high head pressure, and efficient for long-distance and high-resistance transport. 7. The impeller and transmission gears are separated from the pump chamber, reducing wear, noise, and maintenance costs while ensuring long life and energy efficiency. 8. Can be equipped with a drive system for adjustable flow and metering purposes. 9. Capable of handling gas, liquid, and solid materials, including three-phase mixtures. Viscosity up to 1,000,000 CP and 55% solids slurry can be conveyed. 10. Easy to maintain, with minimal wearing parts and low operating costs. ### 3. Applications - **Food Industry:** Yogurt, whipped cream, ice cream, cheese blocks, whey, beer, malt, yeast, jam, syrup, soda, juice, pudding, tomato sauce, sesame paste, peanut butter, spices, cooking oil, etc. - **Chemical Industry:** Gels, facial cleansers, hand soaps, shower gels, detergents, shampoos, cosmetics, fragrances, glycerin, fatty acids, paints, resins, adhesives, and more. - **Pharmaceutical Industry:** Pills pastes, emulsifiers, syrups, medicines, ointments, biological products, vaccines, health supplements, etc. - **Construction Industry:** Paints, coatings, ceramic glazes, and corrosion-resistant materials. - **Other Industries:** Plastics, textiles, paper, coal flotation agents, nanomaterials, and bio-chemicals. ### FAQ 1. **Q: Are you a factory? How many workers do you have?** A: Yes, we are a factory. We have two factories located in Guangzhou and Jiangsu. Our workforce consists of approximately 100 employees, and we have 18 years of experience in cosmetic machinery. 2. **Q: What about after-sales service?** A: We offer a two-year warranty for large equipment such as hydraulic homogenizers and vacuum emulsifying mixers. For smaller filling machines like semi-automatic labeling machines, the warranty is one year. Free replacement of non-defective wearing parts is provided during the warranty period, excluding delivery charges. 3. **Q: What about installation?** A: Our engineers can be sent to your country, but the customer is responsible for air tickets and accommodation during the visit. 4. **Q: What should I do if I encounter a problem with the machine?** A: Please send us a photo or video of the issue. For small machines, we will provide a solution via video. For larger machines, our engineer will visit your site (customer pays travel expenses). 5. **Q: How do you ensure quality and delivery time?** A: All machines are tested before packaging. We use strong wooden packaging to ensure safe delivery over long distances. --- Let me know if you'd like this formatted for a website or product page!
