Pharmaceutical & Chemical Pumps (APIs, Buffers, CIP, Solvents)
From aggressive solvents and acids to high-purity buffers and CIP, we match containment, cleanliness, and control to your process. Mag-drive for hazardous transfer, digital/peristaltic metering for precision dosing, progressive-cavity for gels and slurries, AODD for portable duty, and multistage/inline centrifugals for water systems. Brands: Finish Thompson, Iwaki, LMI, Neptune, Emec, Walchem, Netzsch, Wilden, Yamada, ARO, Grundfos, Goulds, Griswold, Flux, J.L. Wingert, BJM, Gorman-Rupp.
Best-Fit Pumps for Pharma & Chemical Duty
| Service | Best Pump Type | Recommended Brands | Why It’s Best |
|---|---|---|---|
| Solvent/acid transfer (VOC, corrosives) | Mag-drive sealless centrifugal (PP/PVDF/ETFE) | Finish Thompson DB/UC; Iwaki MX/MD | Leak-free containment; broad compatibility and easy maintenance |
| API/buffer dosing, pH control | Digital diaphragm metering / Peristaltic | LMI PD/TD; Neptune 500/600; Emec; Walchem; LMI KML/KBL | High turndown accuracy; peristaltic excels with off-gassing/ crystalline media |
| High-viscosity gels, slurries, crystallizers | Progressive-cavity (VFD) | Netzsch | Low-shear, steady flow at very high viscosity/solids |
| CIP/SIP recirc and utility water | Inline / end-suction centrifugal | Grundfos TPE; Grundfos NB/NK; Griswold; Goulds | Efficient, sanitary-friendly layouts; back-pull-out service |
| RO/UF water systems & booster skids | Multistage centrifugal (VFD) | Grundfos CR | Compact high head, strong efficiency, excellent controllability |
| Portable transfer / totes, reactors | AODD (bolted, plastics or SS) | Wilden; Yamada; ARO | Air-powered safety; run-dry and dead-head tolerant |
| Drum/IBC unloading & day tanks | Drum/IBC pump + injection hardware | Flux; J.L. Wingert (columns, quills) | Ergonomic make-up; validated dosing and sampling hardware |
| Sumps/spill containment | Submersible (corrosion-resistant) / self-priming | BJM (submersible); Gorman-Rupp (self-priming) | Immersed reliability or above-grade serviceability |
Compliance note: On select models we can support documentation for USP water service, material declarations, and validation accessories. We confirm elastomers/plastics vs. SDS.
Recommended Pharma/Chemical Packages (Placeholders)
Tip Send SDS, target GPM/TDH, viscosity vs. temp, required documentation, and controls I/O. We’ll return curves and a validation-ready BOM.
How We Engineer Pharma & Chemical Duty
- Containment: sealless where compatible; proper venting and secondary containment.
- Dosing accuracy: back-pressure, anti-siphon, calibration columns, and quills.
- Shear & viscosity: PC/peristaltic for gels; VFDs to reduce tip speed.
- Water systems: BEP/VFD selection for RO/UF; stainless or polymeric wetted sets.
- Serviceability: isolation valves, drains/vents, and standardized wear kits.

Pharma & Chemical Pump FAQs
When do I choose mag-drive vs. a sealed pump?
Select mag-drive for compatible solvents/corrosives or VOC containment; otherwise we specify the correct seal plan and flush for your fluid and temperature.
Peristaltic or diaphragm for buffer/API dosing?
Use digital diaphragm for clean chemicals at pressure; choose peristaltic for off-gassing, crystallizing, or shear-sensitive fluids with hose-only wetted parts.
What documentation can you provide?
Curves, IOM, material declarations, calibration records, and validation accessories on select models. We align with your URS.
