pump

also called electric pump · fuel pump · transfer pump · water pump

A MACHINE THAT MOVES A FLUID FROM ONE PLACE TO ANOTHER AND RAISES ITS PRESSURE ON THE WAY - an in-tank petrol pump, a diesel lift pump, a hand drum pump, a submersible sump pump, an aquarium air pump. IT HANGS DIRECTLY UNDER `Product` AND UNDER NO AUTOMOTIVE BRANCH, and it is filed by UNSPSC in segment 40 (distribution and conditioning systems) at class 40151500, where `Fuel pumps` 40151532 is ONE OF SEVENTY-SEVEN COMMODITIES beside `Water pumps` 40151510, `Oil pumps` 40151524, `Air pumps` 40151501, `Sewage pumps` 40151517, `Hand pumps` 40151506, `Submersible pumps` 40151513, `Inline pump` 40151571, `Centrifugal pumps` 40151503, `Gear pumps` 40151551, `Diaphragm pumps` 40151548, `Plunger pumps` 40151527, `Turbine pumps` 40151526 and sixty-five more. SEVENTY-SEVEN LEAVES, FOUR QUESTIONS. Read that list and the commodities sort themselves without residue into WHAT IS PUMPED (fuel, water, oil, sewage, chemical), WHAT DRIVES IT (hand, solenoid, engine), HOW IT MOVES THE FLUID (centrifugal, gear, vane, screw, diaphragm, plunger, turbine, lobe) and WHERE IT SITS (inline, submersible, sump, well, booster). Four properties, not seventy-seven classes - the 2026-08-25 amendment applied to the corpus itself, and the reason `FuelPump` is not a class here. It would have had to earn an exclusive slot over `Pump` and it has none: every fact a fuel pump publishes - a duty, a drive, a mechanism, a siting, a flow at a pressure, a delivery pressure, a voltage, a port thread - is a fact any pump publishes, and the fuel is a VALUE of the first of them. AND THE MAKERS THEMSELVES PROVE THE FOUR MUST BE FOUR AND NOT FEWER [A5]. Carter files `Mechanical` under a field it calls `Pump Design`; Delphi files `Turbine` under the SAME field name on the FE0114. One field carrying a DRIVE on one house's sheet and a HYDRAULIC PRINCIPLE on another's is precisely the conflation this pool exists to refuse, so `pump_drive` and `pump_mechanism` are two slots. And the siting is a third, published by Bosch on its own datasheet as `Housing version: inline`, by Delphi as `Position(s): In-Tank`, by Airtex as `Position: In Tank` against `Position: In-Line`, and by Bosch in its own prose on the FP 200-7: `an inline roller cell pump for the installation outside the fuel tank (installation in the tank is not proven)` - which is the [A13] proof that the siting is not a way of installing one product but a way of building two. `flow_rate` FOUNDS `FlowUnits` AND DISCHARGES THE MACHINERY HALF OF b153's H1-f2. The pool had thirty unit vocabularies and nothing for volumetric flow, so a filter's rated flow was unsayable; a pump's is its headline number, so the family is founded here - as RATE UNITS, `u_litre_per_hour` and `u_gallon_per_hour`, carrying the `per` inside the unit exactly as the live `u_rpm` does [A14]. Its `reference_pressure` is REQUIRED, and one pump published twice is the proof: Walbro's GSS342 is advertised `255 LPH @ 40 PSI` and independently measured `261 LPH @ 43.5 PSI` against a stated operating range of `15-90 PSI`. Bosch puts the same condition in the FIELD NAME - `Gasoline delivery rate at 5 bar and 22 C` and, on the same sheet, `Diesel delivery rate at 7 bar and 22 C` - which is also why `pump_duty` and `flow_rate` are both cardinality many. NOTHING WAS RE-MINTED THAT THE POOL ALREADY HOLDS, AND THE PRESSURE FAMILY IS NOW CLEANLY THREE [A11]. `pump_pressure` is RE-DECLARED here from `EspressoMachine` under [L5] and its definition generalised - it always was `the pressure a pump develops`, and Bosch's `Fuel pressure: 8 bar`, Walbro's `Operating Pressure` and Delphi's `System Pressure: 62 psi` are the same fact an espresso machine's 9 bar is. `integral_valve` is RE-DECLARED from `OilFilter` with its existing `valve_opening_pressure` qualifier, because Bosch publishes `Non-return valve: Internal` and `Pressure limiting valve: 8.5 bar rel.` on the FP 300 - a check valve and a relief valve with a set pressure, which is exactly the shape b153 built for a filter's anti-drainback and bypass valves. `voltage` AND `power_rating` are RE-DECLARED from `PoweredProduct`, and this class is deliberately NOT parented under it - BUT NOT FOR THE REASON THE DRAFT GAVE, which the adversary showed was false on the pool's own facts [A-9]. Nothing would be FORCED: every one of `PoweredProduct`'s five slots is cardinality `one` and none is required, so an unanswerable one is the settled tolerance [H2-f7] and not the bucket failure. The real reason is that the parenting would assert something FALSE. `subclass_of` is is-a, and a quarter of this class consumes no supplied power at all: UNSPSC attests `Hand pumps 40151506`, `Treadle pump 40151582`, `Gravity pump 40151579` and `Ram pumps 40151554`, and Carter's M6626 is a camshaft-driven diaphragm pump with no supply whatever. So the two slots that DO apply to the electric members are re-declared under [L5] and the class stays under `Product`. `power_rating` earns its place on the non-automotive half: Pedrollo publishes rated power as a headline field on its own datasheets (D8 `0.55 kW`, D30 `1.1 kW`, the F series `1.5 to 75 kW`), and it is one of the two numbers the entire water-pump trade is sold on. The service-temperature pair is re-declared from `Grease` on Bosch's `Operating temperature range: -20 to 90 C`; `thread_size` is re-declared from `SparkPlug`/`Filter` with the new `thread_role` qualifier, on Bosch's `Mech. connector intake side M18x1.5` and `pressure side M12x1.5`. Length, diameter, mass and colour are the spine's already - Bosch prints `Diameter 50 mm`, `Length 174 mm`, `Weight 714 g` and `Color: Red` for the FP 300 and this class re-mints none of them. WHAT IS DELIBERATELY NOT HERE. The current draw (`Load current at 5 bar and 22 C: 17.3 +/- 1 A`) has no home, because the pool has no electric-current unit family - the b153 `rated_flow` shape, recorded rather than half-built. The box contents that the aftermarket data layer publishes as a dozen fields - `Fuel Sending Unit Included: No`, `Strainer Included`, `Regulator Included`, `Mounting Bracket Included`, and US Motor Works' sender resistances `Empty: 220.0 Ohms` / `Full: 20.0 Ohms` - are COMPOSITION and are refused on b156's box-contents ruling. The voltage a flow was measured at (`at 14 V`) has no qualifier. And the flow figures are published as BOUNDS (`>300 l/h`), RANGES (`>220 to 270 l/h`) AND TOLERANCES (`340 +/- 5 l/h`) on one maker's sheets - all three shapes of the standing bounds obligation at once, on a sixth trade. WHAT THE SOURCE MAY AND MAY NOT WITNESS. Habib's five pump rows are the DEMAND SIGNAL only [L12] - four Toyota and Bosch in-tank units and one `HEP 02A GBC`, a universal inline plunger pump. Every differentia stands on a document read at the mint: Bosch Motorsport's FP 300, FP 200-7, FP 200-E, FP 200, FP 100, FP 165 and DFP 300 datasheets and its own `FUEL PUMP TECHNICAL DATA` catalogue table, Walbro/TI's published GSS342, GSS340 and F90000267 data, and the Delphi, Airtex, Carter and Denso article records for the FE0114, HFP923, E7000, E2000, M6626 and 951-0022.
