Engineering pre-selection for chemical duty pumps
APPLICATION

Chemical plants — acid unloading & transfer

Concentrated-acid unloading: the concentration band decides the material before the pump type is discussed.

The typical duty

FluidSulfuric Acid 93–98%, 98%
Temperature25 °C
Flow25 m³/h
Head30 m
Viscosity≈ 25 cP
Conditionszero-leakage

What the selector says at this duty

Primary answer at this dutyMagnetic Drive Centrifugal Pump (Metallic, sealless) — Toxic, flammable, expensive or environmentally sensitive fluids — zero leakage
Typical wetted materialsCarbon Steel, Alloy 20 (CN7M), Hastelloy C-276

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

  • 'Sulfuric acid' is three different duties — state the percentage
  • Dilution heat on the suction side is a separate duty
