Sewage & Wastewater Pumps (Collection, Treatment, Sludge & Utilities)
Municipal and industrial wastewater mixes solids, abrasives, fats, and corrosives. We deploy submersible non-clog/chopper for collection, self-priming trash for above-grade service, progressive-cavity for thickened sludge, AODD for portable bypass, mag-drive for chemical transfer, and digital/peristaltic for odor/pH/polymer feed. Brands: Gorman-Rupp, BJM, Goulds, Netzsch, Wilden, Yamada, ARO, Finish Thompson, Iwaki, LMI, Neptune, Emec, Walchem, Flux, Grundfos, Griswold.
Best-Fit Pumps for Sewage & Wastewater
| Service | Best Pump Type | Recommended Brands | Why It’s Best |
|---|---|---|---|
| Collection / lift stations | Submersible non-clog (solids-handling) | BJM; Goulds | Passes wipes and rags; robust motors; guide-rail removal for maintenance |
| Severe ragging / FOG heavy influent | Chopper submersible | BJM (SKG) | Shreds stringy solids and wipes to prevent clogging and restore capacity |
| Headworks/grit, above-grade O&M | Self-priming trash pump | Gorman-Rupp (T/Super T) | Inspection cover and wear-plate access without disturbing piping |
| RAS/WAS (thickened) & dewatering feed | Progressive-cavity (VFD) | Netzsch | Even, low-shear flow for sludge to belt press/centrifuge |
| Bypass pumping & portable transfer | AODD (bolted, abrasion kits) | Wilden; Yamada; ARO | Handles solids and air; run-dry/dead-head tolerant and easy to deploy |
| Chem transfer (hypo, caustic, acid) | Mag-drive sealless centrifugal (PP/PVDF/ETFE) | Finish Thompson DB/UC; Iwaki MX/MD | Leak-free containment for corrosives and oxidants |
| Polymer / odor control / pH trim | Digital diaphragm / Peristaltic metering | LMI PD/TD & KML/KBL; Neptune; Emec; Walchem | Accurate ppm dosing with validation hardware and control integration |
| Chemical make-up & IBC/drum loading | Drum/IBC pump + injection hardware | Flux | Ergonomic drum/IBC handling with fast tube swaps |
| Plant utilities (washdown/recirc) | End-suction/inline centrifugal | Grundfos; Griswold; Goulds | Reliable utility service with simple maintenance |
Integration: We can align to your panel I/O, float trees or transducers, lead/lag logic, and telemetry/alarm requirements.

How We Engineer Wastewater Duty
- Clog & abrasion control: non-clog or chopper hydraulics, hard-iron wear parts, generous NPSH margin.
- Service access: self-priming for above-grade O&M or guide-rail submersible removal.
- Accurate dosing: back-pressure, anti-siphon, calibration columns, injection quills.
- Chem containment: sealless mag-drive for oxidants/caustics; proper vents/secondary containment.
- Controls: lead/lag alternation, run verification, alarms, and telemetry integration.

Sewage & Wastewater Pump FAQs
When do I specify chopper vs. non-clog?
Chopper pumps excel where wipes and rags cause chronic clogging. Non-clog fits cleaner influent with passable solids and lower energy draw.
Is self-priming better for maintenance?
Yes—self-priming offers above-grade inspection and wear-plate access. Submersibles shine where footprint/noise or inundation drive a wet-well install.
How do you keep polymer and hypo dosing consistent?
We combine digital/peristaltic metering with back-pressure, anti-siphon, calibration columns, and injection quills—plus controls integration for alarms and turndown.
