Sanitary Centrifugal Pump

1. Clean media delivery 

Its core function is to transport various fluid media with high hygiene standards, including food and beverages (milk, juice, beer, syrup), pharmaceutical raw materials (medicinal liquid, distilled water, oral liquid), daily chemical products (face cream, shampoo) and biological agents (fermentation liquid, nutrient solution), etc. The flow parts have no dead corners to avoid media contamination.

2. Low-shear material protection 

With an optimized impeller structure design, it generates low shear force during operation, which can reduce structural damage to easily emulsified, particulate, or heat-sensitive media, ensuring the stability of the original composition and properties of the material. It is suitable for conveying special materials such as yogurt, sauces, and vaccine intermediates.

3. High-efficiency and stable pressurized delivery 

It leverages centrifugal force to lift and transport media over long distances, providing stable head and flow rate according to working conditions. It meets the process requirements of material transfer, filling, and circulation between different processes in the workshop, and is suitable for positive or negative pressure conveying scenarios.

4. CIP/SIP in-situ cleaning and sterilization

It supports Clean In-In (CIP) and Sterilize In-In (SIP) operations, and can complete internal cleaning and high-temperature sterilization without disassembling the pump body, greatly simplifying the cleaning process, reducing the risk of cross-contamination, and complying with FDA, GMP and other hygiene certification standards.

5. Leak-free sealing protection 

Equipped with sanitary mechanical seals or aseptic sealing components, it can effectively prevent media leakage and the intrusion of external impurities, ensuring a clean production environment and avoiding the waste of valuable media. It is suitable for pharmaceutical and bioengineering fields with stringent sealing requirements.

I. Media Requirements 

1. Applicable Media: Clean fluids such as food and beverage, pharmaceutical fluids, daily chemical emulsions, biological agents, and pure water. 

2. Parameter Range: Viscosity ≤ 500 mPa·s; Temperature -20℃ to 150℃; Particle size ≤ 0.5mm, content ≤ 0.1%. 

3. Contraindications: Strictly prohibited from conveying highly corrosive, flammable, explosive, highly abrasive slurries and media containing large particles/fibers.

II. Installation and Operation Conditions

1. Ambient temperature and humidity: 5℃~40℃, humidity ≤85%, no condensation. 

2. Site requirements: Flat and firm ground, with ≥0.5m of maintenance space; free of dust and corrosive gases, meeting GMP cleanroom standards. 

3. Electrical configuration: AC 220V/380V/415V, 50Hz/60Hz; motor protection ≥IP55, outdoor installation requires a rain cover.

III. Adaptation to Special Working Conditions 

1. Aseptic scenario: Optional aseptic seal + clamp connection, supports SIP sterilization. 

2. Positive and negative pressure conveying: Upgraded negative pressure/high pressure resistant seal. 

3. Explosion-proof requirements: Optional Ex d II BT4 explosion-proof motor.

1. Food and beverage industry 

It can transport materials such as milk, yogurt, juice, beer, wine, syrup, cooking oil, and sauce. The low-shear design can protect the taste and nutrients of the materials and meet food-grade production standards.

2. Pharmaceutical and Biotechnology Industry 

It can transport pharmaceutical solutions, distilled water, oral solutions, vaccine intermediates, fermentation broth, nutrient solutions, etc., meeting GMP aseptic production requirements and supporting CIP/SIP cleaning and sterilization to avoid cross-contamination.

3. Daily Chemical and Cosmetics Industry

It can deliver viscous materials such as face cream, lotion, shampoo, shower gel, and serum. The smooth flow channel leaves no residue, ensuring product purity and stability.

4. Pure water and water purification industry 

Used for the transportation and circulation of reverse osmosis pure water and ultrapure water, it meets the high-purity water needs of the electronics and medical fields, and its corrosion-resistant material avoids secondary water pollution.

5. Dairy processing industry 

It is used in processes such as fresh milk pretreatment, cheese liquor transportation, and ice cream base transfer. The hygienic seal prevents impurities from entering and ensures the safety of dairy products.

I. Before powering on 

1. Close the inlet and outlet valves, fill the pump chamber with the medium, and do not run it dry; clean the inlet filter. 

2. Check the power supply voltage and confirm that the motor rotation is clockwise; check that the mechanical seal is adequately lubricated.

II. Startup and Operation 

1. Open the inlet valve → start the motor → after the pressure stabilizes, slowly open the outlet valve and adjust to the required flow rate. 

2. Monitor the pressure, flow rate, and equipment noise; ensure there is no abnormal vibration. Prolonged operation with the outlet valve fully closed is strictly prohibited.

III. Shutdown and Maintenance 

1. Close the outlet valve → disconnect the power → close the inlet valve; drain the residual medium from the pump chamber. 

2. For routine cleaning, use CIP (Clean In-Place) for cleaning in place; for aseptic operation, perform SIP (Sterile In-Place) sterilization, controlling temperature and time. 

3. For long-term shutdown: thoroughly clean and dry, seal the inlet and outlet; periodically manually rotate the pump to prevent jamming.

IV. Safety Precautions 

Power off and label the area before maintenance; take proper protective measures when operating with high-temperature media; and ensure that the sterile workshop follows GMP standards.
