Jiangsu Chuangjin Pump & Valve Manufacturing Co., Ltd.

A quotation saying only “CJB intelligent self-priming pump” leaves major construction decisions open. Chuangjin publishes more than one CJB sealing arrangement, including a slurry brochure describing dynamic sealing and a synchronous-pump brochure describing mechanical seals. Establish which drawing and manual govern the offered unit before comparing price, utilities or maintenance.

The synchronous CJB brochure describes single-face, double-face and cartridge mechanical-seal arrangements with oil, water or pumped-liquid cooling alternatives. Its selection discussion distinguishes dirty or hot-water service, clean-liquid self-cooling and slurry/easily crystallising service. A family name does not establish that auxiliary water is unnecessary, nor that every unit is mechanically seal-less.

For a dirty stream, state what clean service water is actually available. For a liquid where fresh-water ingress is unacceptable, make that restriction explicit and ask which cooling/isolation arrangement is proposed. For crystallising slurry, include solids, temperature changes and shutdown deposits, then request the seal drawing and the startup, flushing and shutdown instructions for that exact construction.

The control description includes local/remote operation and high-level start with low-level stop. Write an operating sequence with the required level thresholds, restart conditions, alarms and response to failed priming. Agree which sensors, control cabinet, interlocks and cables are included. A catalogue picture of a cabinet does not define the project’s electrical scope.

The currently linked CJB slurry introduction discusses dense slurry, particles, flooded/high-pressure inlet conditions and blockage or wear in conventional arrangements. It describes a dynamic sealing combination with alternative cooling arrangements. That is distinct from the mechanical-seal configurations in the synchronous brochure; the selected construction needs its own parts schedule and service requirements.

Supply density and solids concentration with their measurement basis, particle size distribution/hardness, fibres, settling behaviour, chemical composition and normal/maximum temperature. Explain whether suction is flooded or under lift, including minimum and maximum levels. Ask for the offered impeller, passage dimensions, wetted materials, seal construction and operating limits against those conditions.

Claims of percentage efficiency improvements, longer life, no leakage and broad replacement of other pump types are not used here as order guarantees. Request a selected curve and an agreed test basis, and distinguish catalogue design features from measured results for the supplied pump. For essential service, identify the expected wear components and a maintenance access plan before ordering.

The existing product page retains the 2,900 r/min row of Chuangjin’s IHF table. This provides a specific centrifugal reference alongside the more installation-dependent CJB directions.

The IHF description offers fluoroplastic alternatives involving FEP and PVDF. Confirm the actual lining/wetted-part schedule, seal and chemical compatibility for the concentration and temperature of the process stream. A broad acid/alkali label is not sufficient for mixed chemicals or cleaning duty. Include the coupling/base, installation dimensions and motor supply in the quotation.

The immersed-pump documentation describes four suction heads arranged across a pit, with agitators below the heads and cutting mechanisms for fibrous material. The heads can also provide support, with a bracket arrangement described as another option. This is a layout decision: show the intended collection points, floor shape, deposits and structural supports rather than selecting only by discharge diameter.

The brochure describes service up to 60°C with concentration around 30%, but its particle-size statement is incomplete because the unit is missing. No particle-diameter limit is inferred here. Give the actual particle sizes, hardness and fibres and request confirmation for the supplied passages and cutting arrangement.

The documented immersion ranges distinguish PWDL at 1.5–1.8 m, PWXL at 1.5–2.0 m and PWCL at 2.5–2.8 m. Another company description transposes letters in the first designation. Use the selected assembly drawing and confirmed code when ordering; do not attach the longest immersion length to every version. Include liquid levels, inlet positions, bottom clearance, discharge pipe loads and safe lifting space above the pit.

The company describes its predecessor as a Jingjiang metallurgical/chemical equipment factory established in 1985 and a reorganisation in 2010. Its profile lists machining, casting, assembly and inspection/test operations. These are company-reported history and facilities; they do not establish the inspection results, material traceability or test capacity allocated to your order.

A Jingjiang government notice dated 17 July 2026 names 江苏创进泵阀制造有限公司 for a proposed pump-valve production-line technical retrofit in Shengci. It describes equipment and production changes planned after construction. This supports the named entity and proposed local manufacturing activity. The notice is a proposed-approval publication, not evidence that the retrofit is completed or that its planned output is already available.

1. Approve the exact construction

   Agree the selected code/speed, impeller and wetted materials, seal/cooling system, control scope and installation drawing.

2. Agree a traceable test package

   State the duty and liquid/test basis, required material records, dimensional checks and identification of the supplied assembly.

3. Set the service boundary

   Confirm the manual, seal and wear spares, installation/commissioning responsibilities, quantities and destination-specific delivery requirements.
