Product Overview

The sanitary magnetic centrifugal pump is specifically designed for GMP-compliant applications in pharmaceutical, biotechnology, and food industries. It addresses traditional issues of shaft seal leakage and wear by replacing dynamic mechanical seals with welded static isolation sleeves, ensuring leak-free and wear-resistant operation. The pump features a compact, reliable structure suitable for conveying clean liquids without solid particles, including pure water, pharmaceuticals, beverages, alcohol, and other liquid products.

Key Features and Advantages

• Use of welded static isolation sleeves instead of dynamic mechanical seals eliminates leakage and wear problems.
• Simple, easy-to-disassemble design facilitates cleaning with no dead zones, meeting GMP hygiene standards.
• All wetted parts are made from high-grade stainless steel (316L/304), ensuring corrosion resistance and compliance with pharmaceutical quality management practices.
• Impellers are available in semi-open and closed types, both designed for easy cleaning and no dead corners.
• Sealing rings are made from silicone rubber or fluorine rubber, suitable for various chemical compatibilities.
• Permanent magnetic coupling driven by the motor eliminates the need for shaft seals, preventing leaks and contamination.

Applications

The pump is widely used in pharmaceutical, cosmetic, chemical, beverage, petroleum plating, and food industries for transporting acids, alkalis, oils, rare and precious liquids, toxic and volatile liquids. It is especially suitable for handling flammable, explosive, and leak-prone liquids. Additionally, it finds applications in environmental protection and water treatment sectors.

Technical Specifications

The pump models vary in power from 0.37 kW to 15 kW, operating at 380 V with full load currents ranging from 0.95 A to 29 A. Inlet and outlet diameters range from DN20 to DN80, accommodating different flow requirements. Below is a summary of selected models:

Working Principle

The pump operates by using a permanent magnetic coupling mounted on the motor shaft to drive the impeller without direct mechanical contact. This design eliminates the need for dynamic shaft seals, preventing leakage and contamination. The welded static isolation sleeve acts as a hermetic barrier between the motor and the pumped fluid, ensuring sanitary conditions and compliance with GMP standards.
