The pharmaceutical industry has extremely strict requirements for the cleanliness and compliance of the production environment. Traditional oil-lubricated vacuum pumps generate oil mist during operation, posing a risk of contaminating pharmaceutical raw materials, intermediates, or finished preparations. They also require regular oil changes and maintenance, making it difficult to meet GMP requirements for equipment cleaning and traceability. Leynow oil-free vacuum pumps adopt an oil-free lubrication structure to prevent oil contamination from entering the vacuum system from the source, and have become the preferred configuration for multiple processes such as freeze-drying, drying, filtration, concentration, solvent recovery, and pharmaceutical packaging.
Challenges Faced by the Industry
The requirements of pharmaceutical production for vacuum systems are not just about "pulling a vacuum", but more importantly, cleanliness, corrosion resistance, verifiability, and traceability. In practical applications, customers often encounter the following types of problems:
Risk of Oil Contamination
Oil-lubricated vacuum pumps generate oil mist during exhaust, which may contaminate pharmaceutical raw materials, intermediates, or finished preparations, affecting drug purity and safety.
Solvents and Corrosive Gases
Pharmaceutical processes often involve organic solvents and acid-base gases. Ordinary vacuum pumps are easily corroded, leading to seal failure and shortened lifespan.
GMP Compliance and Validation
The pharmaceutical industry has clear requirements for equipment materials, cleaning validation, and operational records. Equipment must be easy to clean, validate, and trace.
High Maintenance Costs
Vacuum pump oil needs to be replaced regularly. Downtime for maintenance and consumable costs add up, affecting continuous production and overall usage costs.
Leynow Pharmaceutical Industry Solutions
Targeting the actual working conditions of the pharmaceutical industry, Leynow provides overall vacuum solutions centered on oil-free vacuum pumps, forming a complete service closed loop from equipment selection and material matching to post-maintenance.
Clean and Oil-free Vacuum Acquisition Method
Oil-free vacuum pumps adopt a self-lubricating structure, and the inner wall of the cylinder is specially treated. They do not generate oil mist or exhaust gas, preventing lubricating oil from entering the vacuum system, meeting the pharmaceutical industry's requirements for cleanliness and GMP.
Corrosion Resistance and Solvent Working Condition Matching
For corrosive working conditions such as organic solvents and acid-base gases, optional corrosion-resistant coatings and sealing materials can reduce the risk of pump body corrosion and extend equipment service life.
Guarantee of Stable and Continuous Operation
For scenarios requiring long-term continuous operation such as freeze-drying and concentration, the heat dissipation and lubrication structures are optimized to reduce the risk of pump body overheating and maintain stable vacuum degree output.
Full-cycle Service and Parts Guarantee
Providing installation and commissioning, regular follow-up visits, and maintenance contract services. Repair parts are Leynow original genuine parts. All repair projects come with a 12-month warranty to reduce unplanned downtime.
