Food Processing Pumps (Hygienic Transfer, Dosing & CIP/SIP)
Move product safely—from bright liquids to viscous pastes—while protecting texture and meeting sanitary standards. We package sanitary AODD for gentle, portable transfer; sanitary centrifugal for bright liquids and CIP returns; peristaltic for shear‑sensitive or inclusion‑rich fluids; progressive‑cavity for high‑viscosity pastes; and digital metering for CIP/SIP chemistry and micro‑ingredient dosing. For aggressive cleaning chemistries, we add mag‑drive sealless transfer. Brands: Wilden, Yamada, ARO, Graco (sanitary lines), Grundfos (hygienic centrifugal), LMI, Neptune, Emec, Walchem, Finish Thompson, Iwaki, Flux, Netzsch, Roper, Blackmer, BJM, Gorman‑Rupp, Goulds, Griswold and J.L. Wingert.
Best‑Fit Pumps for Food Processing
| Processing Duty | Best Pump Type | Recommended Brands | Why It’s Best |
|---|---|---|---|
| Chunky sauces, slurries, particulates | Sanitary AODD (polished 316L, tri‑clamp) | Wilden, Yamada, ARO, Graco | Gentle on inclusions; portable; CIP/SIP options; easy changeover |
| Bright liquids (water, juice, brine), CIP return | Sanitary centrifugal | Grundfos (hygienic series) | Smooth, efficient flow; cleanable surfaces; low shear |
| Shear‑sensitive or pulp‑filled products | Peristaltic | LMI KML / KBL | Low shear dosing/transfer; accurate at low flow; sanitary tube swaps |
| Pastes, concentrates, tomato & meat emulsions | Progressive‑cavity (sanitary) | Netzsch | Steady, low‑pulsation flow at high viscosity; protects texture |
| Oils, syrups, chocolate tempering | External gear (food‑grade) | Roper, Blackmer | Constant flow vs. speed; performs at viscosity and back‑pressure |
| CIP/SIP chemical dosing (caustic/acid/sanitizer) | Digital diaphragm metering (PVDF/PTFE) | LMI PD/TD, Neptune 500/600, Emec, Walchem | High turndown; accurate ppm; PLC/SCADA integration |
| Bulk cleaning chemical transfer | Mag‑drive sealless centrifugal (PP/PVDF/ETFE) | Finish Thompson DB/UC, Iwaki MX/MD | No mechanical seal → fewer leaks; broad chemical compatibility |
| Ingredient drum/IBC unloading | Sanitary drum/IBC pump | Flux F‑Series | Food‑grade tubes; tri‑clamp options; ergonomic handling |
| Plant waste sumps, floor drains | Submersible dewatering / self‑priming trash | BJM (submersible), Gorman‑Rupp (self‑priming), Goulds/Griswold | Solids handling to keep areas clean; fast service access |
| Verification & sanitary accessories | Tanks, calibration columns, injection quills | J.L. Wingert | Auditable dosing; safe injection; compliant instrumentation |
Note: We match materials (316L, FDA elastomers) and finishes (Ra) to your QA plan; 3‑A/EHEDG models quoted where required.

How We Engineer Hygienic Flow
- Materials & finish—316L, FDA elastomers; surface finish to spec (e.g., ≤ Ra 32 µin) and drainable housings.
- Shear & texture—peristaltic/AODD for inclusions; PC for viscous pastes; centrifugal for bright liquids.
- Controls—dose‑to‑flow/residual, 4–20 mA/pulse, batching and interlocks to fillers/pasteurizers.
- CIP/SIP integration—spray coverage, return velocities, elastomer compatibility and vent/relief design.
- Maintainability—tool‑less disassembly, back‑pull‑out designs, quick‑change tubes and isolation spools.

Food Processing FAQs
When is sanitary AODD better than centrifugal?
AODD excels with inclusions or variable viscosity where gentle handling and portability are key. Sanitary centrifugal is best for bright liquids and CIP return at higher flows.
Peristaltic vs. progressive‑cavity for viscous products?
Peristaltic is ideal for low‑flow, low‑shear dosing/transfer. Progressive‑cavity is better for continuous, higher‑flow movement of thick pastes and concentrates with low pulsation.
How do I handle aggressive CIP chemicals safely?
Use PVDF/PTFE‑headed metering pumps for accurate dosing and mag‑drive sealless pumps for bulk transfer of oxidants/alkalis to minimize leaks and maintenance.
