A complete, shareable page for a single pump. It plots the performance curve (head, efficiency and NPSHr against flow, with the best-efficiency point marked, or dosing flow against stroke), decodes the API 682 / ISO 21049 mechanical seal plan, and lists the full specification — duty and operating range, drive and motor, materials of construction, build and reliability, connections, weight and certifications. Pop-up panels give the type-specific preventive-maintenance schedule (daily to annual tasks with procedures) and a troubleshooting guide (symptoms, probable causes and recommended solutions).
Run a centrifugal pump near its BEP and keep dosing pumps in their recommended stroke band. Data is from the engineering reference database — confirm against the manufacturer's certified curve before procurement.

Send your influent analysis and our engineers assess your process and recommend a tailored treatment solution — free, confidential and no obligation.
Select the regulatory standard for your country — it sets which parameters we need for a compliance-aware process assessment.
Required parameters for the chosen standard are flagged on the sample form. You can still submit a partial set and we will advise what else to test.
Your sample is stored against your company so we can track the project. Provide a company name or email as a minimum.
