Cooling Tower Pumps (Condenser Water, Basin & Chemistry)
Keep towers efficient and clean with reliable condenser water pumps, smart chemical feed, and practical basin handling. We specify split‑case / end‑suction for condenser service, digital diaphragm metering for biocides and inhibitors, mag‑drive for chemical transfer, and rugged submersible/self‑priming options for basin cleanup. Brands: Grundfos, Goulds, Griswold, LMI, Walchem, Neptune, Emec, Finish Thompson, Iwaki, Flux, BJM and Gorman‑Rupp.
Best‑Fit Pumps for Cooling Towers
| Task | Best Pump Type | Recommended Brands | Why It’s Best |
|---|---|---|---|
| Condenser water circulation | Horizontal split‑case / end‑suction | Grundfos, Goulds, Griswold | High reliability at large flows; double‑suction options for low NPSHr |
| Biocide & inhibitor feed | Digital diaphragm metering | LMI PD/TD, Walchem EWN, Neptune 500/600, Emec, Grundfos DDA/DMX | Accurate ppm control; PVDF/PTFE wet ends; easy integration with controllers |
| Chemical transfer to day‑tanks | Mag‑drive sealless centrifugal (PP/PVDF/ETFE) | Finish Thompson DB/UC, Iwaki MX/MD | Leak‑free; ideal for oxidants/corrosives; low maintenance |
| Drum/IBC unloading | Drum/IBC pump | Flux F‑Series | Ergonomic, fast unloading; XP motor options |
| Basin cleaning / sump transfer | Submersible slurry or self‑priming trash | BJM / Gorman‑Rupp | Handles sand, silt and debris; easy service and clean‑out |
| Side‑stream filtration loop | End‑suction or mag‑drive centrifugal | Grundfos / Griswold, Finish Thompson / Iwaki | Steady, non‑pulsing flow through filters & separators |

How We Engineer Cooling Tower Systems
- Hydraulics—size to condenser ΔP at design GPM; verify NPSH with tower elevation and basin level.
- Materials—bronze/SS‑fitted wetted parts for open water; coatings per water quality.
- Chemical feed—dose‑to‑flow, residual control, interlocks and alarms; calibration columns and injection quills.
- Cleanliness—side‑stream filters plus basin cleanout pumps to control fouling and legionella risk.
- Serviceability—back‑pull‑out designs, isolation valves, and easy strainer access.

Cooling Tower FAQs
Split‑case vs. end‑suction for condenser water?
Split‑case offers high reliability and low NPSHr at large flows; end‑suction is compact and economical for smaller towers. We match to flow/head, footprint and service strategy.
Which materials stand up to tower water?
Bronze or stainless‑fitted pumps resist corrosion in open systems. Strainers, coatings and correct elastomers extend service life when water quality is variable.
Do I need side‑stream filtration?
Yes, for most towers. A small constant‑flow loop reduces fouling, improves heat transfer and lowers chemical usage. We size the pump for filter ΔP at design flow.
