Data centres — liquid cooling circulation
Glycol-water loops for server cooling — clean fluid, continuous duty, efficiency and reliability over heroics.
The typical duty
| Fluid | Ethylene Glycol, 30% |
|---|---|
| Temperature | 35 °C |
| Flow | 120 m³/h |
| Head | 45 m |
| Viscosity | ≈ 4 cP |
What the selector says at this duty
| Primary answer at this duty | End-Suction Centrifugal Pump (ANSI B73.1) — Clean or lightly contaminated fluids, moderate duty, flows ~2–400 m³/h |
|---|---|
| Typical wetted materials | Cast Iron, Carbon Steel, Polypropylene (PP), Stainless Steel 304, Stainless Steel 316L, PVDF, PTFE / FEP lined |
The answer above is the tool's own output at the duty shown — run your actual numbers through it; your duty point may move the answer. The full report adds the alternatives worth quoting in parallel.
What to watch
- Glycol percentage decides viscosity — state it
- Redundancy (N+1) is a commercial, not hydraulic, decision
