How to Select the Right Pump for Pharmaceutical Liquid Fillers: A Technical Guide by Lingyao Experts

Introduction

Choosing the optimal pump for pharmaceutical filling machines directly impacts production efficiency, product sterility, and regulatory compliance. As a leader in GMP-certified equipment manufacturing, Lingyao Company shares actionable insights to streamline pump selection for injectables, biologics, and oral solutions.

Key Selection Criteria

1. Fluid Properties & Compatibility
   • Viscosity Range: Rotary lobe pumps for high-viscosity suspensions (e.g., ointments), while peristaltic pumps suit shear-sensitive biologics (e.g., mRNA vaccines).
   • Material Safety: Opt for 316L stainless steel or PTFE-coated pumps to avoid chemical interactions with APIs (Active Pharmaceutical Ingredients).
2. Precision & Compliance Requirements
   • Achieve ±0.5% dosing accuracy with servo-driven piston pumps, critical for low-volume fillers like insulin pens.
   • Ensure pumps meet FDA 21 CFR Part 11 for electronic records and ASME BPE standards for cleanability.
3. Sterility Assurance
   • Use CIP/SIP-enabled pumps (Clean-in-Place/Sterilize-in-Place) for aseptic processing lines, reducing contamination risks in lyophilized drug production.

Industry-Specific Recommendations

1. Biopharmaceuticals
   • Select pumps with ≤0.5% pulsation to protect cell therapy media integrity.
   • Case Study: LY-RP30 pumps reduced protein aggregation by 60% in monoclonal antibody production.
2. Oral Liquids & Syrups
   • Use magnetically driven centrifugal pumps for high-flow rates (up to 500L/min) in pediatric syrup lines.
