Solid-Laden Fluid Transfer (Soft Solids, Particulates & Mixed Phases)
When your fluid carries fibers, pellets, pulp, seeds, crystals, or fines, the wrong pump shreds product—or plugs lines. We apply AODD for portable/variable service, peristaltic for abrasives and air, progressive-cavity for gentle, pulse-free transfer of viscous mixes, non-clog/submersible for pits, and self-priming trash for above-grade O&M. Brands: Wilden, Yamada, ARO, Graco, Netzsch, BJM, Gorman-Rupp, Goulds, Griswold, Finish Thompson, Iwaki, LMI, Neptune, Emec, Walchem, Flux, J.L. Wingert, Roper, Blackmer.
Best-Fit Pumps for Solid-Laden Fluids
| Service | Best Pump Type | Recommended Brands | Why It’s Best |
|---|---|---|---|
| General solids transfer / variable duty | AODD (bolted; large ball/seat) | Wilden; Yamada; ARO | Run-dry/dead-head tolerant; passes soft solids; portable, easy to clean |
| Abrasive or air-entrained streams | Peristaltic hose pump | Graco; LMI KML/KBL | Only hose is wetted; handles grit/fines and variable suction with ease |
| Viscous with entrained solids (food, slurries) | Progressive-cavity (low-shear) | Netzsch | Gentle, pulse-free conveyance protects particulates and texture |
| Pits/sumps with solids | Submersible non-clog / agitator | BJM | Moves settled solids; rugged seals/impellers for dirty service |
| Above-grade access / clean-out | Self-priming trash pump | Gorman-Rupp (T/Super T) | Quick wear-plate adjustments and inspection cover for plug clearing |
| Binder/pH/preservative dosing | Digital diaphragm / Peristaltic metering | LMI PD/TD & KML/KBL; Neptune; Emec; Walchem | Accurate ppm with back-pressure, anti-siphon, and calibration hardware |
| Cleaning & chemical transfer | Mag-drive sealless centrifugal (PP/PVDF/ETFE) | Finish Thompson DB/UC; Iwaki MX/MD | Leak-free containment of caustic/acid cleaners and solvents |
| Drum/IBC loading of additives | Drum/IBC pump + injection hardware | Flux; J.L. Wingert | Ergonomic transfers with calibrated injection and sampling |
Sizing: We’ll ask for solids type/size, % by weight, viscosity vs. temp, SG, duty points, allowable shear, and sanitary requirements (if any).

How We Engineer Solid-Laden Duty
- Passage sizing: ports/balls/valves sized to your max particle and PSD.
- Low shear options: PC and peristaltic for texture-sensitive or fragile solids.
- Wear control: elastomer, hose, and metallurgy choices for abrasives.
- Serviceability: self-primers and guide-rail subs to minimize downtime.
- Dosing validation: back-pressure, anti-siphon, columns, and quills.
Common Solid-Laden Uses

- Cooling tower blowdown solids
- General plant sumps
- Portable transfer & cleanup
Gentle on Product. Tough on Clogs. Easy to Own.
Send PSD/max particle, % solids, viscosity vs. temp, SG, shear limits, and CIP needs. We’ll size a serviceable package with curves and a complete BOM.
Solid-Laden Transfer FAQs
AODD or peristaltic—what should I pick first?
Start with AODD for portable or variable duty. Choose peristaltic when abrasion, suction lift, or air entrainment dominate—and quick hose swaps beat rebuilds.
When does progressive-cavity make sense?
When you need gentle, pulse-free flow for viscous mixes with particulates—especially where shear damages product texture or floc.
How do you prevent plugging in long runs?
We size passages to max particle, keep velocity in the solids-transport window, maintain NPSH margin, and select wear parts/metals suited to your solids.
