Two Chinese Centrifugal Pumps Receive Product Carbon-Footprint Labels
Two centrifugal pumps from a Chinese manufacturer have received product carbon-footprint labels, with published figures covering raw materials, production, logistics, use and end-of-life over a stated 20-year design life.
Lead
Two centrifugal pumps manufactured by Shanghai Liancheng Group Suzhou Co., Ltd. (上海连成集团苏州股份有限公司) have received product carbon-footprint labels, according to an announcement carried by the pump branch of the China General Machinery Industry Association on 8 October 2026.
Facts
The products. The certified products are the SLW200-315G horizontal single-stage, single-suction centrifugal pump and the SLOWN350-400-4 single-stage, double-suction, split-casing centrifugal pump. The first is rated at 37 kW and the second at 220 kW, says the manufacturer's published data. (Source: the pump branch's announcement, 2026-10-08.)
The accounting basis. The announcement names GB/T 24067-2024, Greenhouse gases — Product carbon footprint — Requirements and guidelines for quantification, and T/JSAS 085-2025 as the basis for the assessments. It describes a full-life-cycle boundary covering raw-material acquisition, manufacturing, warehousing and logistics, use, and end-of-life treatment. (Source: the same.)
The declared results. Both assessments use a stated design life of 20 years. The published figures are per unit over that accounting boundary, not annual emissions and not manufacturing-only figures. (Source: the same.)
| Model | Construction stated | Net mass | Rated power | Declared product carbon footprint |
|---|---|---|---|---|
| SLW200-315G | Horizontal, single-stage, single-suction centrifugal pump | 510 kg | 37 kW | 1,250,132.39 kg CO₂e |
| SLOWN350-400-4 | Single-stage, double-suction, split-casing centrifugal pump | 2,700 kg | 220 kW | 7,430,455.01 kg CO₂e |
The certification status. The announcement states that both products received product carbon-footprint labels after assessment. It does not identify the assessment body in the published text. (Source: the same.)
The stated applications. The manufacturer lists the SLW200-315G for industrial and municipal water supply and drainage, building pressure boosting, irrigation, fire-duty pressure boosting, long-distance transfer and heating or cooling circulation. The SLOWN350-400-4 is listed for waterworks, air-conditioning circulation, building water supply, irrigation, drainage pumping stations, power plants, industrial water systems, fire systems and marine duties. These are catalogue applications, not orders reported in the certification announcement. (Source: the same.)
The label's stated use. The announcement says the carbon-footprint label may be used on the product, its packaging and related materials to display the declared emissions data. It does not publish a comparison with another pump or claim that certification itself reduces emissions. (Source: the same.)
The two product configurations. The smaller certified unit is a horizontal, single-suction machine, while the larger one is a double-suction, split-casing machine. Their published net masses and rated powers are therefore reported as separate product facts; the announcement does not present the two footprints as a like-for-like efficiency comparison. (Source: the same.)
The manufacturer's design statement. The announcement says both pumps use optimised hydraulic models and links their development, procurement and production to energy management. It does not publish a pump curve, an efficiency percentage or a measured annual electricity-saving figure for either model. (Source: the same.)
The certification record. The reported figures belong to two identified models and their declared assessment conditions. The announcement does not extend the same numerical results to other pumps in the manufacturer's range. (Source: the same.)

Note on sourcing. This item reports a manufacturer's certification announcement carried by an industry association. We record the models, accounting basis and declared figures without treating the label as an efficiency rating or a comparative environmental assessment. We do not rank or recommend suppliers.
What the source does not state
The announcement does not name the assessment body or give certificate numbers. It does not publish a stage-by-stage emissions breakdown, the electricity-consumption assumptions for the use phase, the load profile, or the electricity mix used in the calculation.
Update note
This item is a dated record of a publicly reported certification. We append corrections rather than rewrite history; corrections are marked Correction with the date.
