Septic & Sump Tank Pumps (Solids-Handling, Grinder, Dewatering)
Septic tanks, wet wells, and building sumps demand reliable solids handling, level-smart control, and easy service. We apply submersible non-clog and grinder/chopper pumps for raw sewage, self-priming trash pumps where above-grade serviceability matters, AODD for portable bypass and cleanup, progressive-cavity for thick sludges, and mag-drive + metering for chemical feed/odor control. Brands: BJM, Gorman-Rupp, Goulds, Wilden, Yamada, ARO, Netzsch, LMI, Neptune, Emec, Walchem, Finish Thompson, Iwaki, Flux, Grundfos.
Best-Fit Pumps for Septic & Sump Tanks
| Service | Best Pump Type | Recommended Brands | Why It’s Best |
|---|---|---|---|
| Raw sewage / lift stations | Submersible non-clog (solids-handling) | BJM; Goulds | Passes wipes/solids; robust motors; float or transducer level control |
| Stringy or heavy solids (ragging) | Chopper / Grinder submersible | BJM (SKG) | Severe duty impellers shred rags to maintain flow and reduce clogs |
| Above-grade ease of service | Self-priming trash pump | Gorman-Rupp (T/Super T) | Accessible inspection cover; fast clean-out without pulling the pump |
| Portable bypass / wet-well cleanup | AODD (bolted, abrasion options) | Wilden; Yamada; ARO | Run-dry/dead-head tolerant; handles air entrainment and debris |
| Thickened sludge recirculation/transfer | Progressive-cavity (VFD) | Netzsch | Pulse-free, low-shear conveyance at high viscosity/solids |
| Odor control / pH / hypochlorite feed | Digital diaphragm or Peristaltic metering | LMI PD/TD & KML/KBL; Neptune; Emec; Walchem | Accurate ppm with back-pressure, anti-siphon, and calibration columns |
| Chemical transfer (NaOCl, acid/caustic) | Mag-drive sealless centrifugal (PP/PVDF/ETFE) | Finish Thompson DB/UC; Iwaki MX/MD | Leak-free containment; excellent chemical compatibility |
| Drum/IBC chemical loading | Drum/IBC pump + injection hardware | Flux | Ergonomic transfers; quick tube set changeovers |
Controls: We support float trees, pressure transducers, and panel integration for auto-duplex/lead-lag operation and alarm telemetry.

How We Engineer Sumps & Septic Duty
- Clog resistance: non-clog, grinder, or chopper hydraulics selected to the debris profile.
- Serviceability: above-grade self-priming options or guide-rail submersible designs.
- Controls: lead/lag alternation, alarm setpoints, and transducer/float redundancy.
- Chem feed: validated metering kits with back-pressure, anti-siphon, columns, and quills.
- Materials: elastomers/hard-iron where abrasion or H2S is present.

Septic & Sump Pump FAQs
Non-clog, grinder, or chopper—what’s right for me?
Non-clog passes solids efficiently; grinders macerate smaller flows; choppers tackle heavy ragging and wipes. We size to solids, flow, TDH, and clog history.
When should I pick self-priming over submersible?
Choose self-priming for above-grade access and rapid clean-out; choose submersible where footprint, noise, or inundation risk favors a wet-well install.
How do you keep chemical dosing accurate in lift stations?
We package metering with back-pressure, anti-siphon, calibration columns, and injection quills—plus control integration for alarms and run verification.
