how it is driven
also called drive · pump drive
WHAT TURNS OR WORKS THE PUMP - an electric motor, the engine it is bolted to, a hand lever, or a supply of compressed air. Carter publishes `Pump Type: Mechanical` on the M6626 and Delphi publishes `Pump Type: Electric` on the HFP923, which is the field, and the two values are two of Habib's own shelves: an in-tank electric unit and the camshaft-driven diaphragm pump every carburettor engine used. NOT DERIVABLE FROM `voltage` [A13]: run the function and a hand pump and an engine-driven pump both return `no voltage` and are told apart by nothing, while an air-operated diaphragm pump has no voltage either and is a third thing again; UNSPSC attests all of them - `Hand pumps` 40151506 beside `Solenoid pumps` 40151515. DISTINCT FROM `pump_mechanism`, and the makers themselves prove the two must be split: Carter files `Mechanical` under a field it calls `Pump Design`, which is where Delphi files `Turbine` - one field carrying a DRIVE on one house's sheet and a HYDRAULIC PRINCIPLE on another's, which is the value conflation this pool exists to refuse [A5]. Concern measurement.
How it is driven is answered with one word chosen from the pump drives list — the same word shared across every product that uses it.
It belongs to measurement — its measurable, physical facts.
asked by the kinds that answer it
1 kind answers it, each for a single value. The same question can be reused by unrelated kinds — one meaning, many homes.
