STRUCTURED MODEL DATABASE
Positive Displacement Pumps
A fixed volume is trapped and displaced during each operating cycle.
What this node is for
Positive Displacement Pumps sits on the working-principle axis. Use it when the physics of energy transfer is already decided and you need families, envelopes and materials underneath that choice. Confirm NPSH, specific speed band and the offered impeller on the manufacturer curve before you treat two rows as alternatives.
If the table is empty, the taxonomy still wants this name in the map — it is not a finding that the product cannot be sourced. Describe the duty in an RFQ rather than waiting for a row to appear.
