1. What is the liquid?
Identify the medium, concentration, solids content and any abrasive or hazardous characteristics.
Start with the medium and duty. The lab narrows Rapid Allweiler’s published pump technologies into sensible starting families.
Use this to prepare the first technical conversation.
Identify the medium, concentration, solids content and any abrasive or hazardous characteristics.
Provide the operating flow range if known rather than only a pipe diameter.
Share the target duty point and system context where available.
Both can materially change technology, material and seal decisions.
Installation space, suction conditions, motor supply, control philosophy and environmental constraints all belong in the brief.
