Chemical Pump Selection: Four Worked Examples

Four real selection cases worked end to end: concentrated sulfuric acid transfer, a toxic volatile solvent on suction lift, an abrasive acid slurry, and closed-loop solvent circula...

Specific Gravity in Pump Selection: Power, Pressure, and Priming Effects

Specific gravity leaves the pump curve untouched and changes everything around it: pressure and shaft power scale with density, and self-priming lift divides by it. This guide expl...

NPSH Explained: Available vs Required and Cavitation Prevention

NPSH reduces to one comparison: what the system offers versus what the pump demands, protected by at least 0.5 to 1 m of margin. This guide builds NPSHa term by term with a worked ...

How to Read a Centrifugal Pump Performance Curve

A pump curve answers five questions: head at each flow, efficiency and BEP, maximum power demand, NPSH required, and how trims and speeds move all four. This guide reads each eleme...

The Chemical Pump Duty Data Sheet: What Your Supplier Needs

Every wrong pump started as an incomplete inquiry. This guide defines the complete duty data sheet: chemistry, physical properties, operating duty, and site constraints, with what ...

How to Select a Chemical Pump: A Six-Step Methodology

Chemical pump selection is elimination in a fixed order: medium, duty, material, drive and seal, priming, then NPSH and motor. This guide walks the six steps with the reasoning beh...
