Pumps for liquids; liquid elevators

1. Scope and Applicability

This PCR applies to complete pumps that move liquids by mechanical or physical action and to complete liquid elevators placed on the market. It covers rotodynamic and positive-displacement pumps, hand or power-driven pumps, metering or dispensing pumps, and liquid elevators, provided that the foreground data package declares the pump principle, pumped-liquid compatibility, driver configuration, duty point, construction materials, and delivered market state.

The core dataset boundary is cradle-to-factory-gate production of a finished pump. It includes upstream production of purchased components, preparation or machining performed by the reporting manufacturer, assembly, production testing, packaging, and treatment of manufacturing wastes. Installation, distribution after the factory gate, maintenance, operational electricity, pumped-liquid losses during use, and end-of-life are outside this core boundary and require separate scenarios. The EU water-pump regulation demonstrates that operational energy can dominate life-cycle impacts for its covered clean-water rotodynamic subset; therefore a use-stage model must not be inferred from the manufacturing reference flow and must instead use declared duty, efficiency, load profile, and operating hours.

Separately supplied parts for pumps or liquid elevators, air or vacuum pumps, compressors, hydraulic or pneumatic power engines, valves, and lifting or conveying equipment that does not move a liquid are excluded. A pump integrated into another product is covered only when the pump itself is the declared foreground output and its mass and manufacturing exchanges can be separated from the host product.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_product_mass	finished pump reference product	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Measure net finished-pump mass after production testing and before shipment packaging; normalize all inventory exchanges to 1 kg net pump.

declared_starting_condition	Purchased pump-specific components and semi-finished parts at the reporting factory gate; raw materials replace those components only for fabrication performed inside the foreground boundary
starting_condition_role	Prevent double counting between purchased component datasets and on-site fabrication while preserving the real first foreground crossing
product_classification_scope	Complete products within CPC 43220; separately supplied pump parts remain upstream inputs or products outside this PCR identity
recursive_input_rule	A complete pump purchased for incorporation into a pump system is recorded once as an upstream product input with its own dataset and is not decomposed again in the receiving process; a part is recorded as the specific part or material at its actual crossing condition
upstream_dataset_requirement	Every purchased component, material, electricity, water, lubricant, and packaging flow requires a geographically and technologically appropriate upstream dataset; supplier-specific data are preferred for high-mass or high-impact inputs
disclosure	Declare vertical integration, purchased-versus-fabricated condition, included driver and controls, test-loop configuration, packaging boundary, cut-offs, waste destination, reporting period, site geography, and allocation choices

rule_id	applies_to	rule	source_ids
