Liancheng presents itself as a Shanghai manufacturer of pumps, valves, environmental equipment and electrical controls. The indexed pump families are SLS/SLW pipeline centrifugals, SLQS split-case, WQ sewage and XBD fire sets—the water-and-building core of a much wider company website.
Buyers often meet Liancheng next to Kaiquan on the same tender. That is a commercial fact, not a dimensional fact. SLS is not KQL. XBD is a Chinese fire-set designation used by many plants; the certificate is model- and year-specific.
The English company profile claims a large plant footprint. Until a current document is on file, treat 550,000 m² as a supplier statement, not a measured KanBeng figure.

How to read this plant
Figures in the ledger are supplier or public-site claims until a document is on file. Capabilities are routing tags. The evidence label is the only statement KanBeng makes about how far review has gone.
- City and founding year identify the record; they are not quality scores.
- Plant area and headcount stay labelled as claims.
- Series letters are crowded across Chinese catalogs—use this factory’s drawing, not a generic booklet.
- A listing is not an endorsement, a factory audit or a product certificate.
Official-site profile; plant and capability claims have not been independently audited by KanBeng.
Indexed series
These are published catalog families KanBeng could attach to this manufacturer. Ranges are envelopes, not a promise that one frame covers the whole band. Open the model record for materials, installation and selection notes.
Liancheng SLQS split-case pumps are offered for water supply, circulation and fire-water storage transfer.
Buyer note: Lock rotation, nozzle orientation and test standard in the purchase order.
SLS Series Vertical inline centrifugal 5–1800 m³/h 8–80 m ISO 2858 / GB/T 5657Liancheng SLS is the group’s vertical pipeline centrifugal line for HVAC and municipal transfer, published on the English company site as a core building-service product.
Buyer note: Confirm Liancheng curve, motor brand and mechanical-seal plan. SLS is not a drop-in for Kaiquan KQL or generic ISG.
SLW Series Horizontal inline centrifugal 5–1800 m³/h 8–80 m ISO 2858Liancheng SLW is the horizontal pipeline counterpart used where a low-profile in-line machine is preferred.
Buyer note: Match suction conditions and NPSH to the issued SLW sheet. Do not interpolate from another factory’s ISW table.
WQ Series Submersible sewage 8–2500 m³/h 6–45 m GB/T 24674Liancheng WQ sewage submersibles cover municipal and industrial wastewater lift. Impeller geometry is model-specific.
Buyer note: Specify cutter vs channel impeller, cable and cooling jacket requirements in writing.
XBD Series Fire pump set 10–300 m³/h 30–200 m GB 6245Liancheng XBD fire-pump packages are sold as electric or diesel-driven sets with controllers. Certification scope is not implied by the series letters.
Buyer note: Demand the current fire-product certificate, controller listing and factory test curve for the exact set.
What this record is not
- Valve and environmental-equipment capability on the corporate site is not evidence that a given pump series is made in-house.
- An XBD nameplate is not a GB 6245 or NFPA 20 listing for the driver and controller combination you were quoted.
- A Liancheng catalog envelope is not permission to copy another factory’s ISG/ISW table.
If you name this factory on an RFQ
- Ask which Liancheng legal entity issues the invoice and the performance test.
- For fire sets, demand the current certificate set for pump, driver and controller together.
- For SLQS, specify rotation, nozzle layout and hydrostatic test pressure.
- Separate pump, valve and control-panel lead times; they are not one machine.

Questions buyers actually ask
Is this factory verified?
Read the evidence label on this page. Source pending means we captured a public identity and catalog families. It is not a site audit, a process-capability study or a product certificate.
Can I order from the envelopes on this page?
No. Envelopes are index ranges from public catalogs. The controlling document is the manufacturer-issued curve, material schedule and test grade for the serial you buy.
Why do so many factories share series letters?
Chinese pump designations are crowded. The factory name plus the drawing number is the product. The three letters are a filing cabinet.
How do I put this plant on an RFQ?
Use Send a requirement and name the factory. Incomplete duty points are not forwarded as if they were specifications.
