A feed tank is a hygienically designed storage vessel used to supply raw materials, active pharmaceutical ingredients (APIs), solvents, and intermediates to a pharmaceutical production process. These tanks act as controlled buffer sources, enabling a continuous or batch-wise flow of ingredients while supporting accurate process regulation and flow consistency.
By maintaining a stable and sanitary supply of materials, stainless steel feed tanks are essential for minimizing process interruptions and increasing efficiency in pharmaceutical manufacturing. Gpi Pharma designs and manufactures custom-built feed tanks that meet the highest industry standards, with full compliance to GMP and FDA guidelines.
Do you have a question about our feed tanks?
Custom feed tanks for continuous and batch production
Our pharmaceutical feed tanks are more than just vessels. They serve as active links in your production process. Whether integrated into upstream buffer preparation or downstream formulation and filling, each stainless steel feed tank is designed for precision, hygiene, and long-term durability. We provide tailored solutions for both aseptic and non-aseptic environments.
Thanks to modular engineering and flexible production methods, we offer feed tanks from our factory or assembled on-site, ensuring smooth integration with your facility and production line.

FAQ
Can a pharmaceutical feed tank be used for both batch and continuous production?
Yes. Gpi Pharma feed tanks are designed to support both batch-wise and continuous production processes. Each feed tank is custom-built to match your specific production setup, whether you operate a batch production line, a continuous process, or a combination of both. Volume, agitation, connections, and instrumentation are all configured to ensure reliable and precise ingredient supply throughout your manufacturing cycle.
How are pharmaceutical feed tanks cleaned and sterilized?
Gpi Pharma feed tanks are equipped with integrated CIP and SIP systems, allowing the vessel to be fully cleaned and sterilized in place without disassembly. This design meets the strictest GMP and hygiene standards. The internal surface finish of Ra ≤ 0.6 µm or better further supports reliable cleaning cycles by minimizing product adhesion and contamination risk.
What materials are used in GMP-compliant stainless steel feed tanks?
Gpi Pharma manufactures feed tanks in high-grade stainless steel, including 1.4404 (316L) and 1.4571, as well as duplex and super duplex grades for more demanding chemical environments. All gaskets and seals are made from FDA-approved materials such as PTFE or silicone, ensuring full compliance with pharmaceutical hygiene and material safety requirements.
