Kaiquan is a Shanghai pump and water-system group whose English site presents municipal, building, power, petrochemical, mining and water-conservancy duties as the commercial frame. The indexed families here are the ones KanBeng could pin to a public product line: pipeline centrifugals, split-case water, stainless vertical multistage and sewage submersibles.
The risk on this record is interchangeability. KQW, KQL, KQSN and KQDP sit in the same buyer conversations as ISW, ISG, split-case S and CDL names from other factories. The letters travel. The hydraulics, motor frames and seal plans do not.
Treat Kaiquan as a full-range water OEM with a large public catalog, not as a verified site audit. Plant area and headcount are not stated in the sources this index currently holds.

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.
Identity and product scope captured from the company website; no independent site audit 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.
Kaiquan KQDP is a stainless vertical multistage family for boosting, RO feed and high-rise supply. Stage count and motor power define the actual duty, not the series letters alone.
Buyer note: Check chloride content before 304 stainless. Confirm stage count, minimum flow and motor IE class on the Kaiquan data sheet.
KQL Series Vertical inline centrifugal 5–1500 m³/h 8–80 m GB/T 5657 / ISO 9906Kaiquan KQL is a vertical in-line centrifugal series used in plant rooms where floor area is constrained. Hydraulic coverage is published by stage of impeller diameter, not a single nameplate.
Buyer note: Confirm rotation, motor IEC frame, noise class and exact impeller diameter against the issued KQL curve.
KQSN Series Axially split double-suction 100–12000 m³/h 10–140 m GB/T 5657Kaiquan KQSN covers axially split, double-suction centrifugals for waterworks, circulation and industrial cooling. Nozzle orientation and rotation are factory options.
Buyer note: Specify rotation, nozzle arrangement, bearing lubrication and witness-test grade. Split-case series names are not dimensional equivalents across factories.
KQW Series Horizontal inline centrifugal 5–1500 m³/h 8–80 m GB/T 5657 / ISO 9906Kaiquan KQW is the group’s horizontal pipeline centrifugal family for HVAC, municipal transfer and building water. Duty envelopes vary by impeller trim and motor frame.
Buyer note: Ask for the Kaiquan curve revision, NPSH, motor efficiency class and flange standard. Do not treat KQW as interchangeable with other ISW-style names.
WQ Submersible Series Submersible sewage 10–3000 m³/h 6–50 m GB/T 24674Kaiquan WQ-class submersible sewage pumps are sold for municipal lift stations and industrial wastewater. Solids handling depends on impeller type (channel, vortex or cutter).
Buyer note: State solids size, fiber content, starts/hour, cable length and guide-rail system. Request the exact impeller drawing, not only the WQ letters.
What this record is not
- A Kaiquan series code is not a drop-in for Liancheng, East Pump or a generic GB pipeline pump with the same letters.
- A website product photo is not a witness-test curve or a fire-listing file.
- “Group” in the legal name does not, by itself, identify which legal entity will stamp the nameplate.
If you name this factory on an RFQ
- Name the exact Kaiquan series and impeller trim, not “ISW equivalent”.
- Ask for the current Q-H curve revision, NPSH3 and motor IE class.
- For KQSN split-case, lock rotation and nozzle arrangement in the purchase order.
- For WQ sewage, state solids size, fiber, starts/hour and guide-rail hardware.

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.
