Product Overview

IHG Vertical Stainless Steel Pipeline Chemical Pump is a single-stage vertical in-line centrifugal pump with stainless steel wetted parts designed for corrosive chemical liquid transfer in pipeline systems.

It addresses corrosion resistance, compact installation, and direct in-line circulation requirements in chemical process networks.

It is suitable for pipeline-mounted chemical transfer, acid and alkali circulation loops, solvent handling systems, and industrial liquid distribution lines.

✔ This pump is engineered for corrosion-resistant vertical in-line chemical transfer where space-saving and standardized pipeline connection are required.

Model Designation

IHG Vertical Stainless Steel Pipeline Chemical Pump

Applications

Typical Operating Scenarios

  • Vertical in-line installation in chemical circulation pipelines
  • Acid and alkali transfer within confined mechanical rooms
  • Solvent recirculation systems requiring stainless steel wetted parts
  • Industrial process liquid booster in compact piping layout
  • Mildly corrosive media transport in closed-loop systems

Engineering Advantages

Structural Design Logic + Engineering Result

Vertical in-line casing structure minimizes installation footprint and eliminates base alignment requirements.

Stainless steel wetted components provide corrosion resistance for chemical media compatibility.

Direct-coupled motor configuration reduces transmission loss and mechanical complexity.

Closed impeller hydraulic design ensures stable head and efficiency performance.

Pipeline flange connections conform to standardized dimensions for easy integration.

How to Select a Pump Model

Determine required flow rate and total dynamic head at design duty point.

Verify stainless steel material compatibility (304 / 316 / 316L) with process liquid.

Ensure system working pressure does not exceed 1.6 MPa.

Select appropriate motor speed (1450 or 2900 rpm) based on energy efficiency and noise requirements.

Match flange size with pipeline DN specification.

✔ Model selection shall be based on hydraulic duty matching, corrosion compatibility, and standardized pipeline integration requirements.

Engineering Notes

Mechanical seal configuration should match medium volatility and temperature.

Not suitable for high-abrasive slurry applications.

Proper ventilation is required to avoid air entrapment in vertical configuration.

Cavitation margin must be evaluated based on available NPSH.

Compliance & Quality Assurance

Hydraulic performance test according to ISO 9906.

Dimensional conformity verification for pipeline standards.

Material traceability for stainless steel components.

Rotor dynamic balancing inspection.

Optional third-party inspection upon request.

Safety Notice

Do not operate under dry-running condition.

Ensure proper venting before startup.

Do not exceed rated pressure and temperature limits.

Disconnect power before maintenance.

OEM & Customization

This pump series supports engineered configuration and duty-based matching. Technical adjustments can be made according to system requirements and installation conditions.

Available options include:

• Stainless steel grade (304 / 316 / 316L)
• Mechanical seal configuration
• Motor voltage & frequency
• Explosion-proof motor
• Flange standard customization

Configuration is determined based on duty point and project specifications.
