WaterPurification.online Water Tools

Interactive calculators that turn customer inputs into calculated requirements, a preliminary treatment train and — where configured — matching WaterPurification.online products.

Water Solution Finder

Enter known water conditions. Unknown values can be left at the default; laboratory testing should be used before final system selection.

Pump Curve & Duty Point

Enter two points from a manufacturer’s pump curve. The tool estimates where the pump operates against the simplified system head entered below.

Pump point 1 — Flow (L/min)
Pump point 1 — Head (m)
Pump point 2 — Flow (L/min)
Pump point 2 — Head (m)
Static system head (m)
System friction coefficient

Important: These tools provide preliminary estimates only and are not a substitute for a qualified site assessment, laboratory water analysis, hydraulic design or the pump/filter manufacturer’s published performance data. Final equipment selection should be checked against actual duty conditions, applicable standards and manufacturer specifications.
