Technical overview
About these figures
These figures provide simplified information for searching, filtering and initial comparison. They are not a complete specification. Exact details depend on the model and configuration.
Power rating: Usually the motor’s rated mechanical output (P2). Electrical input power (P1) is a different value. Check the product’s nameplate or manufacturer’s documentation to confirm which rating applies.
Outlet size: The nominal size class is expressed on a millimetre basis: for example, DN40 denotes a nominal 40 mm size. It does not specify the exact measured opening, connection type, thread, flange drilling or pressure rating.
Head and flow: Indicative figures describing the pump’s performance envelope, rather than a single operating duty point. Do not assume maximum flow is available at maximum head, or that every combination within the ranges is achievable. Minimum figures do not establish safe continuous operating limits. Consult the relevant performance curve.
Check the product description, nameplate and manufacturer’s documentation before selection or installation. Please contact us before purchasing if you need help confirming suitability or connection details.
