Commercial Laundry Pumps (Detergent, Bleach & Alkali Dosing)
Keep washer‑extractors on recipe and transfer chemicals safely from bulk storage. We package peristaltic dosing for surfactants/softeners, digital diaphragm metering for hypochlorite and sours, AODD transfer for bulk drums/totes, plus drum/IBC and booster/circulation pumps for hot water and RO make‑up. Brands: LMI (including KML/KBL peristaltic), Walchem, Neptune, Emec, Grundfos, Wilden, Yamada, ARO, Flux, J.L. Wingert, BJM and Gorman‑Rupp.
Best‑Fit Pumps for Laundry Rooms & Central Chem
| Task | Best Pump Type | Recommended Brands | Why It’s Best |
|---|---|---|---|
| Detergent, softener & emulsifier dosing | Peristaltic (low shear, simple tubing) | LMI KML / KBL | Handles viscous surfactants; easy tube swaps; stable at low flows |
| Bleach (NaOCl) & sour dosing | Digital diaphragm metering (degassing head) | LMI PD/TD, Walchem EWN, Emec, Grundfos DDA | PVDF/PTFE heads; built‑in degassing; accurate ppm control from PLC |
| Bulk transfer from drums/totes | AODD transfer (portable) | Wilden, Yamada, ARO | Run‑dry/dead‑head tolerant; handles unknown solids; easy maintenance |
| Drum/IBC unloading to day‑tanks | Drum/IBC pump | Flux F‑Series | Fast, ergonomic unloading; XP options; chemical or sanitary tubes |
| Hot‑water/RO booster & circulation | Inline ECM / end‑suction centrifugal | Grundfos (MAGNA/TPE, end‑suction) | Quiet, efficient, wide turndown; ideal for variable load laundry ops |
| Lint pit / sump transfer (utility) | Submersible slurry or self‑priming trash | BJM / Gorman‑Rupp | Solids‑tolerant; easy clean‑out; keeps the room safe and dry |
| Manifolds, day‑tanks & verification | Tanks, calibration columns, quills | J.L. Wingert | Reliable make‑up and accurate, auditable dosing |

How We Engineer Laundry Chemical Systems
- Accuracy & safety—back‑pressure/relief valves, anti‑siphon, injection quills, check valves near the point of use.
- Controls—PLC/washer interlocks (pulse/4–20 mA), batch dosing, low‑level & leak alarms, lockout/tagout.
- Materials—PVDF/PTFE heads for oxidants; Norprene/Viton tubing per chemistry & temp.
- Ergonomics—drum wands, quick connects, labeled manifolds, clear day‑tanks with graduations.
- House utilities—hot‑water/RO booster sizing, sump handling, ventilation and containment.

Commercial Laundry FAQs
Why peristaltic for detergents and softeners?
Viscous surfactants meter cleanly with low shear and simple tube changes. No check valves to foul; easy maintenance between shifts.
How do I prevent siphoning into the washer?
Use anti‑siphon/back‑pressure valves and inject via a quill at the pipe centerline. Keep the chemical line above the injection point where possible.
What about bleach off‑gassing?
Specify digital diaphragm metering with a degassing head, flooded suction, short suction lines and a back‑pressure valve to keep checks seated.
