How to find gear pump manufacturers for cooperation in chemical plants

When seeking cooperation with gear pump manufacturers, chemical plants need to combine their own needs, industry characteristics, and the comprehensive capabilities of suppliers to determine suitable partners through a systematic screening and evaluation process. The following are specific steps and suggestions:

1. Clarify requirements and technical parameters

Working condition requirements: Determine the characteristics of the medium (corrosiveness, viscosity, temperature), flow rate, pressure, head, and other parameters.

Material requirements: Select the pump body material according to the medium (such as stainless steel, cast iron, corrosion-resistant alloy, etc.).

Certification standards: Whether explosion-proof certification (such as ATEX), industry certification (such as API, ISO), or environmental compliance requirements are required.

Budget and after-sales: Clearly define the budget scope and prioritize manufacturers providing installation, maintenance, and spare parts services.

2. Find channels for potential manufacturers

Industry Platforms and Exhibitions:

B2B platforms: Alibaba, Huicong, China Pump Valve Network, etc. When screening, pay attention to the "Integrity Pass" or "Strength Merchant" tags.

Exhibitions: China International Fluid Machinery Exhibition (CFME), Hannover Industrial Exhibition in Germany, etc., direct contact with manufacturer technical teams.

Industry associations and directories:

The membership directory released by China General Machinery Industry Association (CGMA) and Hydraulic Institute of America (HI).

Peer recommendation:

Obtain word-of-mouth recommendations through industry forums (such as Haichuan Chemical Forum) or peer companies.

Search engines and vertical media:

Keywords such as "high-temperature gear pump manufacturer", "corrosion-resistant gear pump supplier", and industry qualifiers (such as "chemical grade").

3. Key points of supplier evaluation**

Technical Capability:

Do you provide customized designs (such as sealing methods, special materials).

Case reference: Request to provide successful cases of chemical media such as sulfuric acid and resin.

Quality Control:

Inquire about the quality inspection process (such as material spectral analysis, performance testing reports).

Request to provide third-party testing certificates (such as SGS, BV).

Production scale:

Conduct on-site inspections of the factory, focusing on the level of equipment automation (such as CNC machining centers) and capacity matching.

after-sale service:

Response time (such as 24-hour technical support), spare parts inventory status.

4. Verification steps before cooperation

Sample testing: It is required to provide samples for working condition simulation testing, with a focus on indicators such as leakage, noise, and efficiency.

Small batch orders: Purchase in small batches first to verify long-term operational stability.

Contract terms:

Clearly define the warranty period (usually 1-2 years) and breach of contract liability (such as compensation for delayed delivery).

Agreement on Technical Confidentiality (if customized design is required).

5. Recommend manufacturers in specific fields for reference

Domestically:

Hengsheng Pump Industry: Focusing on chemical gear pumps, with a wide range of corrosion-resistant material options.

Shiqi Pump Industry: Focusing on various gear oil pumps, slag oil pumps, etc., providing integrated solutions. It is a cost-effective gear pump manufacturer.

International:

Viking Pump (USA): Suitable for high viscosity media.

B ö rger (Germany): Skilled in handling media containing solid particles.

6. Risk avoidance suggestions

Avoid intermediaries: cooperate directly with manufacturers to reduce price differences and communication costs.

Intellectual property protection: If special designs are involved, the patent ownership must be clearly stated in the contract.

Alternative plan: Evaluate at least 3-5 alternative suppliers to avoid relying solely on them.

Through the above steps, chemical plants can efficiently locate gear pump suppliers that meet technical, quality, and service requirements, and establish long-term stable cooperative relationships. If further narrowing of the scope is required, specific operating parameters can be provided (such as medium temperature of 200 ℃+flow rate of 10m ³/h) for targeted recommendations
