The voltage the product is designed to operate at, as a numeral with an electric-potential unit (e.g. 230 V, or a 100-240 V range expressed by its bounds). Optional: many listings omit it. Homes on PoweredProduct. RE-DECLARED ON `Pump` AT b158 UNDER [L5] RATHER THAN PARENTING THAT CLASS UNDER `PoweredProduct`, and the reason is [A3]: `PoweredProduct` would force `installation_type` (freestanding, built-in, countertop, integrated) and `energy_efficiency_class` onto a fuel pump, which is the bucket-and-power_rating failure the whole algorithm was built to prevent, and a camshaft-driven mechanical pump or a hand pump has no supply at all. The trade publishes it plainly: Bosch `Supply voltage: 10 to 16.5 V` with `Operating voltage: 13.8 V` beside it (FP 300), Walbro `Minimum Voltage: 12V` (GSS342), Airtex `Voltage: 12V` (E7000). A limit is recorded with it: a flow figure is itself quoted AT a voltage (`340 +/- 5 l/h at 14 V`, `255 LPH rated at 43 psi and 13.5 volts`) and this property cannot serve as that qualifier without saying two things at once, so the flow's reference voltage is filed as an obligation.
