Petrochemical Pumps (Feedstocks, Intermediates & Utilities)
Process plants demand uptime, containment, and documentation. We size ANSI centrifugal for utilities, mag-drive sealless for corrosives/solvents, gear for lube and hydrocarbons, AODD for portable or unknown fluids, progressive-cavity for viscous slurries, and multistage for pressure sets/boiler feed. Brands: Griswold, Goulds, Grundfos, Finish Thompson, Iwaki, Roper, Blackmer, Wilden, Yamada, ARO, Netzsch, Gorman-Rupp, BJM, LMI, Neptune, Emec, Walchem, Flux, J.L. Wingert.
Best-Fit Pumps by Petrochemical Duty
| Service | Best Pump Type | Recommended Brands | Why It’s Best |
|---|---|---|---|
| Process utilities / transfer (clean) | ANSI B73.1 end-suction / inline | Griswold; Goulds; Grundfos TPE/NB/NK | Standardized footprints, efficient loops, back-pull-out service |
| Corrosives & solvents (aromatics, ketones) | Mag-drive sealless centrifugal (PP/PVDF/ETFE) | Finish Thompson DB/UC; Iwaki MX/MD | Leak-free containment for VOCs and hazardous fluids |
| Hydrocarbons / lube oil circulation | External gear (relief/bypass) | Roper; Blackmer | PD stability across viscosity and temperature swings |
| Viscous slurries / polymer intermediates | Progressive-cavity (VFD) / AODD (portable) | Netzsch (PC); Wilden/Yamada/ARO (AODD) | Low-shear steady flow or rugged portable transfer |
| Tank farm / sump & spill response | Self-priming trash / Submersible | Gorman-Rupp; BJM | Above-grade clean-out or immersed reliability for pits |
| Boiler feed / high service pressure | Multistage centrifugal (VFD) | Grundfos CR | Compact high head with strong efficiency and NPSH margin |
| Chemical injection (inhibitors, scavengers, catalysts) | Digital diaphragm / Peristaltic with validation | LMI PD/TD; LMI KML/KBL; Neptune; Emec; Walchem (control) | Accurate ppm with back-pressure, anti-siphon, calibration columns |
| Drum/IBC unloading & day tanks | Drum/IBC pump + injection hardware | Flux; J.L. Wingert | Ergonomic makeup with correct quills/columns for verification |
Note: On select models, hazardous-area motors/instrumentation and API/ISO options are available. We align metallurgy, elastomers and documentation with your spec.

How We Engineer Petrochemical Duty
- Containment: sealless transfer where compatible; correct seal plans elsewhere.
- Hydraulics: BEP-biased selection, NPSH checks, and surge/relief on PD systems.
- Materials: elastomers/metals vs. aromatics, acids, caustics; chloride awareness.
- Compliance: hazardous-area options and documentation matched to spec.
- Serviceability: back-pull-out frames, clean-out ports, isolation, drains/vents.

Petrochemical Pump FAQs
ANSI centrifugal or mag-drive—how do I choose?
Use ANSI for clean utilities and broad operating windows; choose mag-drive where VOC containment matters and fluid properties suit sealless limits.
What protects PD pumps on hydrocarbon service?
Relief/bypass valves, pressure switches and interlocks—plus suction sizing and NPSH checks for cold-start viscosity.
Can you meet hazardous-area specs?
Yes—on select models we supply hazardous-area motors and instrumentation with documentation aligned to your spec.
