Engineering Principles and Design Considerations
Engineering pharmaceutical manufacturing equipment requires adherence to specialized principles that guarantee product quality, operator safety, and process efficiency. These include:
Sanitary Design and Material Selection
Material choices such as pharmaceutical-grade stainless steel (typically 316L) provide necessary corrosion resistance and cleanability. Surface finishes are critical — electropolishing and passivation reduce sites for microbial adherence.
Clean-In-Place (CIP) and Sterilize-In-Place (SIP) Integration
Equipment is often designed to support CIP/SIP for contamination control. This requires smooth interior surfaces devoid of dead legs and appropriate valve configurations. SKE & Eagle’s water treatment systems also synergize with these cleaning processes, ensuring high purity in critical utilities.
Process Automation and Control Systems
Advanced manufacturing equipment leverages PLC and SCADA systems to maintain tight process control. Sensors monitor parameters like temperature, pressure, and humidity with immediate feedback loops essential for consistent output.
Mechanical and Process Reliability
The design prioritizes reliability under continuous operation. Factors such as bearing selection, drive mechanisms, and wear resistant components reduce downtime. Reliability engineering frameworks, including FMEA (Failure Mode and Effects Analysis), guide component design.
Modularity and Scalability
Modern pharmaceutical equipment often supports modular assembly to facilitate adaptability for evolving product lines or scale-up requirements, allowing manufacturers to optimize production capacity without complete system overhauls.
Compliance with Pressure and Thermal Requirements
Many components operate under precise pressure and thermal constraints (e.g., autoclaves or pressure vessels). Compliance with ASME Boiler and Pressure Vessel Code is integral to equipment safety and legal adherence.
SKE & Eagle’s engineering teams focus on these design philosophies to deliver not only equipment that fulfills requirements but excels in system integration, robustness, and lifecycle value.
Compliance and Regulatory Standards
Pharmaceutical manufacturing operates under exacting regulatory regimes. Equipment must enable compliance with multiple guidelines including:
Good Manufacturing Practices (GMP)
Defined by agencies like the FDA, GMP ensures consistent product quality. Equipment must facilitate traceability, batch documentation, and contamination control through validated design and maintenance protocols.
FDA and EMA Regulations
Approval processes require documentation confirming equipment qualification (IQ, OQ, PQ) and validation. These documents demonstrate reproducible performance consistent with safety and efficacy mandates.
Pharmacopoeial Standards
USP, EP, and JP provide specifications for materials, process conditions, and quality tests affecting equipment design and use especially for water and excipient handling systems.
ISO Standards
ISO 13485 and ISO 9001 quality management standards frequently influence equipment manufacturing processes, driving quality assurance and risk management.
Environmental and Safety Regulations
Equipment must comply with OSHA safety requirements and environmental impact regulations, including handling of hazardous materials and emissions controls.
SKE & Eagle maintains comprehensive knowledge of these standards and ensures that its equipment designs exceed compliance thresholds, enabling pharmaceutical manufacturers to achieve regulatory success efficiently.
Water Treatment Systems in Pharmaceutical Manufacturing
Water is a critical pharmaceutical manufacturing input, often constituting over 70% of the drug product composition. The integrity of pharmaceutical manufacturing equipment relies heavily on supplying and maintaining high-purity water using sophisticated treatment and distribution systems.
Purified Water (PW) and Water for Injection (WFI) Requirements
Water Treatment systems routinely process feed water through filtration, deionization, or reverse osmosis to produce Purified Water, and further distillation or double-pass reverse osmosis for Water for Injection. Both must meet stringent microbial and chemical purity criteria.
