Process Duties
Pharmaceutical and biotech plants run many small, precise pumping duties. Buffer and media transfer feed bioreactors and mixing tanks. Filling and dispensing lines need accurate, repeatable flow. Chromatography and filtration skids need steady, pulse free feed. Fermentation and cell culture processes need gentle handling, because shear can damage cells and proteins. Cleaning and sterilising in place (CIP and SIP) then runs through the same equipment between batches.
Purified Water and Clean Utilities
Purified water and water for injection systems circulate continuously through loops that must stay clean and free of stagnant zones. Sanitary centrifugal pumps with polished internals handle these loops. Around them, plants run clean steam condensate, chilled water and process cooling systems. These utilities don’t touch the product directly, but they still need reliable pumps and good records.
Choosing Pumps for Clean Processes
- Peristaltic pumps: single use or sterile transfer, with only the tubing in contact.
- Diaphragm metering pumps: accurate dosing of reagents and pH control.
- Sanitary centrifugal pumps: purified water loops and thin liquids.
- Lobe pumps: gentle transfer of viscous or shear-sensitive products.
Materials, Finishes and Documentation
Clean processes need the right materials and the paperwork to prove them. Wetted parts are usually 316L stainless steel with a specified internal surface finish. Elastomers must suit the product and cleaning chemicals, and many sites ask for compliance statements for food or pharmaceutical contact. Material certificates, surface finish records and spare part traceability are often part of the order. Tell us your site’s requirements at the start, so the right documents come with the parts.
Hydraulics in Pharma Plants
Hydraulics play a smaller but important role. Tablet presses, packaging machines and some processing equipment use hydraulic power. Units near clean areas need a tidy, leak free design and careful choice of oil, so a leak never becomes a contamination risk.
Keeping Clean Processes Running
Batch processes punish unplanned stops. Keep critical spares such as tubing, diaphragms and seal kits on hand, change them on a schedule rather than waiting for a failure, and record every change. Our lifecycle support service can help build maintenance plans that fit your batch and validation schedule.
Related Process Sectors
Pharma and biotech overlap with other process industries. Hygienic product handling is covered under food & beverage, solvents and reagents under chemical processing, and paper based packaging under paper & pulp.
