Chemical Processing Pumps (Reactor, Utility & CIP)
Move corrosives, solvents, slurries and polymers safely from bulk storage to reactors, day tanks and unit operations. We specify mag‑drive sealless, ANSI centrifugals, metering, AODD, gear and progressive‑cavity packages from Finish Thompson, Iwaki, Goulds, Griswold, LMI, Walchem, Neptune, Emec, Wilden, Yamada, ARO, Roper, Blackmer, Flux, Grundfos, Gorman‑Rupp, Netzsch and more—configured for compatibility, uptime, and compliance.
Pumps That Thrive in Chemical Processing
| Requirement | Best Technology | Recommended Brands | Notes |
|---|---|---|---|
| Acids/solvents transfer in closed systems | Mag‑drive sealless (PP, PVDF, ETFE, 316SS) | Finish Thompson (DB/UC), Iwaki (MX/MD) | No mechanical seal; emissions‑free; ideal for HCl, H2SO4, ketones, aromatics |
| Plant circulation & utility services | ANSI B73.1 end‑suction centrifugal | Goulds, Griswold | Interchangeable dimensions; wide hydraulic coverage; seal or seal‑less options |
| Precise dosing (pH, oxidants, inhibitors) | API‑675 diaphragm metering (hydraulic/solenoid) | LMI PD/TD, Walchem EWN, Neptune 500/600, Emec | PVDF/PFA heads; PTFE diaphragms; back‑pressure/relief; calibration columns |
| Viscous resins/polymers (1,000–100,000 cP) | Progressive‑cavity (low RPM) / external gear | Netzsch (PC), Roper, Blackmer | Low shear, constant flow; jacketed casings available for cold starts |
| Abrasive slurries & fillers | AODD or PC | Wilden, Yamada, Netzsch | Handles solids; run‑dry capable (AODD); elastomer selection by chemistry |
| Drum/IBC feed to day tanks | Drum/IBC pump | Flux F‑Series | Quick‑change tubes; explosion‑proof motor options; sanitary and chemical tubes |

How We Engineer Chemical Processing Pumps
- Compatibility first—wetted materials (PP, PVDF, ETFE, 316SS, Alloy‑20), elastomers (EPDM/FKM/PTFE/FFKM) validated against SDS and temperature.
- Containment—sealless designs, double‑containment canisters, leak‑detection switches, and secondary containment where required.
- NPSH & suction design—degassing heads for off‑gassing oxidants; oversized suction; flooded inlets on viscous feeds.
- Area classification & controls—Class I Div 1/2 motors, bonding/grounding, VFDs with interlocks, flow‑verify and alarms.
- Maintainability—ANSI dimensional interchange; top‑pull or back‑pull‑out designs; quick‑change elastomers on AODD.
Common Processing Tasks & Fluids
- Feed to reactors, neutralizers & blend tanks
- CIP chemical supply & return
- Solvent circulation & filtration skids
- Acid/caustic handling & pH control

Chemical Processing FAQs
When should I choose mag‑drive instead of a sealed pump?
Use mag‑drive for hazardous/volatile fluids, emissions control, and when seal failures are unacceptable. For high viscosity or slurries, we may favor sealed PD pumps or sealless canned‑motor options.
What’s the right metering pump for oxidants or acids?
PVDF/PFA wet ends with PTFE diaphragms. Solenoid drives are ideal for low flows; hydraulic diaphragm or mechanical diaphragm for higher pressure. Add back‑pressure, relief, and a calibration column.
How do you handle abrasive slurries in reactors?
AODD or progressive‑cavity with abrasion‑resistant internals; slow RPM; generous suction; strainers sized to protect valves without starving the pump.
