Municipal Drinking Water Pumps (Raw Intake, Treatment & Distribution)
For potable water plants and boosters we prioritize materials compliance, containment, and efficiency. Multistage and inline sets for pressure, end-suction for process loops, mag-drive for chemical transfer, and digital/peristaltic metering for hypo, fluoride, orthophosphate and pH control. Brands: Grundfos, Goulds, Griswold, Finish Thompson, Iwaki, LMI, Neptune, Emec, Walchem, Flux, J.L. Wingert, Gorman-Rupp.
Best-Fit Pumps for Drinking Water
| Service | Best Pump Type | Recommended Brands | Why It’s Best |
|---|---|---|---|
| Distribution booster / high service | Multistage centrifugal (booster sets) | Grundfos CR (system variants) | Compact high head, strong efficiency, VFD control |
| Process & plant utility loops | End-suction / inline centrifugal | Grundfos NB/NK, TPE; Griswold; Goulds | Quiet, efficient, back-pull-out maintenance |
| Sodium hypochlorite transfer | Mag-drive sealless centrifugal (PP/PVDF/ETFE) | Finish Thompson DB/UC; Iwaki MX/MD | No seal leak path; handles off-gassing better than sealed pumps |
| Hypo dosing (residual control) | Peristaltic or digital diaphragm | LMI KML/KBL (peristaltic); LMI PD/TD; Neptune; Emec; Walchem | Stable turndown; peristaltic excels with off-gassing hypo |
| Fluoride & orthophosphate dosing | Digital diaphragm metering | LMI PD/TD; Neptune 500/600; Emec; Walchem | Accurate ppm with back-pressure/anti-siphon hardware |
| Alum, ferric, caustic transfer | Mag-drive sealless centrifugal | Finish Thompson; Iwaki | Containment for corrosives; broad compatibility |
| Filter backwash / clearwell recirc | End-suction or vertical inline (VFD) | Grundfos NB/NK, TPE; Griswold; Goulds | High-flow controllability and easy service |
| Tote/drum chemical make-up | Drum/IBC pump + injection hardware | Flux; J.L. Wingert (columns, quills) | Ergonomic unloading with validated dosing setup |
Note: NSF/ANSI 61/372 options are available for select models. We confirm elastomers, wetted metals, and documentation with your submittals.

How We Engineer Potable Duty
- Compliance: materials review (61/372 options), gaskets/elastomers and documentation.
- Containment: sealless transfer for hypo/caustic; venting and relief as required.
- Dosing accuracy: back-pressure, anti-siphon, calibration columns and injection quills.
- Hydraulics: BEP selection, NPSH checks, VFD/ECM control for efficiency.
- Serviceability: isolation, drains/vents, back-pull-out frames and standard spares.

Drinking Water Pump FAQs
Why use mag-drive for hypochlorite transfer?
Sealless designs eliminate a leak path around mechanical seals and handle off-gassing better. We pair proper plastics and vents to protect equipment and staff.
Peristaltic or diaphragm for residual control?
Peristaltic excels with off-gassing sodium hypochlorite; digital diaphragm is excellent for fluoride, orthophosphate and caustic where pressure is higher.
Can you furnish NSF/ANSI 61/372 documentation?
Yes—on select models. We confirm materials and provide submittals, certifications and O&M with your quote.
