Stable storage and precise flow control for high-performance pharmaceutical production
What is a buffer tank?
A buffer tank is a hygienic vessel designed to temporarily store active pharmaceutical ingredients, solvents, intermediates, and other process fluids between different stages of pharmaceutical manufacturing. These tanks play a vital role in regulating flow rates, pressure, temperature, and quantity to ensure a consistent and controlled supply of materials throughout the production line.
By absorbing fluctuations in production and preventing disruptions, buffer tanks support stable process conditions and help increase efficiency. Gpi designs and manufactures custom stainless steel buffer tanks that comply with the most stringent industry standards, including GMP and FDA guidelines.
Engineered for process regulation and production stability
Our stainless steel buffer tanks are tailored to your specific pharmaceutical process. Whether used to stage intermediates between filtration and formulation, or to balance input and output in batch and continuous systems, our buffer tanks are essential for achieving process stability and optimizing flow control.
Available in a wide range of volumes, from compact models for small-scale applications to large vessels for commercial production, each tank is designed for maximum durability, hygiene, and performance. With both factory-assembled and on-site build options, integration into your facility is seamless and efficient.
Applications in pharmaceutical and biotech processes
Stainless steel buffer tanks from Gpi are widely used across pharmaceutical and biotechnological operations. They are ideal for:
- Storing intermediate products between critical production steps
- Balancing flow between upstream and downstream processes
- Holding solvents or APIs prior to blending or final formulation
- Conditioning fluids through temperature or pressure regulation
- Preventing bottlenecks by absorbing peaks in production cycles
By stabilizing fluid dynamics within your process, buffer tanks help ensure quality, consistency, and operational efficiency.
Key advantages of our stainless steel buffer tanks
Our tanks are developed to support clean, safe, and continuous operations in pharmaceutical environments. Key features include:
- Durable and hygienic materials: Crafted from corrosion-resistant stainless steel such as 316L or 1.4410 duplex, our tanks are built for long-term use in sterile conditions
- Advanced temperature control: Tanks can be equipped with thermal jackets and insulation to maintain precise fluid temperatures and avoid quality loss
- Accurate level monitoring: Integrated radar, ultrasonic, or capacitive sensors ensure real-time liquid level tracking for reliable flow management
- Integrated process control: Pressure and temperature transmitters help maintain optimal operating conditions, protecting product quality and process continuity
- Rotating and (Custom designed) Static spray balls for effective cleaning: custom designs available.
- Comprehensive safety systems: Features such as overpressure valves, safety relief devices, and alarms provide protection under varying process conditions
- Flexible installation options: Tanks can be installed vertically, horizontally, above ground, or underground, offering versatility for any production environment
- Reinforced construction: Double-walled designs provide extra containment and safety for sensitive or hazardous materials
- Flow control optimization: Optional integration with flow meters ensures precise fluid transfer and process consistency
- Superior surface finish: Ground interior finishes and optional electropolishing reduce contamination risks and simplify maintenance
Technical configurations to match your production goals
Each buffer tank is fully customizable to meet your operational and regulatory needs. Options include:
- Construction materials such as 316L, 1.4571, or duplex stainless steels
- Internal surface finishes with Ra values up to 0.6 microns or better
- Volumes from a few hundred liters to several thousand liters
