Proper lubrication of pharmaceutical equipment is a crucial step in ensuring the quality and safety of pharmaceutical production. When selecting lubricants, pharmaceutical companies must ensure that the lubricants comply with GMP (Good Manufacturing Practice) and other relevant international standards, such as NSF. These standards impose strict requirements on the safety, purity, and suitability of lubricants. Lubricants should be non-toxic, non-corrosive, and chemically inert with respect to the medications to prevent contamination. This is especially important for equipment parts that come into direct contact with medications, where food-grade or medical-grade lubricants should be used.
Key Pharmaceutical Equipment and Lubrication Requirements
Pharmaceutical equipment includes: reactors, shake flask machines, fermentation equipment, crystallization equipment, centrifuges, mixing and stirring equipment, stirring tanks, filling equipment, automatic filling machines, filling lines, etc. Lubricants are needed for the following critical components:
Mechanical Seals
Mechanical seals are crucial components that connect the reactor and stirrer. The sealing rings in mechanical seals must remain lubricated; otherwise, friction damage can occur, affecting the seal's performance.
Bearings
Bearings in reactors are often subjected to heavy loads and require lubricant support. High-temperature resistant greases should be selected to ensure lubrication and prevent unsafe chemical reactions that could damage the equipment and contaminate the products.
Gearboxes
Gearboxes, commonly found in the reactor’s drive system, reduce the rotational speed of the stirrer. Gearboxes require lubrication with oils and greases. Baoxing’s food-grade medical lubricants should be used to ensure effective lubrication without contaminating the final products.
Chains
Chains are commonly used in the drive systems, conveyor systems, and lifting equipment of pharmaceutical machinery, such as granulators, dryers, tablet presses, capsule filling machines, and filling machines. These chain-driven components require lubrication to prevent rust.
Cylinders
Cylinders convert compressed air pressure into mechanical energy, driving movements such as linear reciprocating, swinging, or rotating motions. In pharmaceutical equipment, cylinders are widely used for speed control and to drive conveyor belts and robotic arms. Lubrication is necessary to ensure long-lasting performance.
Pharmaceutical equipment must be regularly lubricated to maintain normal operation, avoid unnecessary chemical reactions, and prevent product contamination. However, every lubricant has its specific application range and limitations. Using the wrong lubricant can have serious consequences for both the equipment and the product. It is essential to strictly follow the equipment's operating instructions for lubrication to ensure both equipment and product safety.
