GDF fluoroplastic liner pipeline centrifugal pump

Vertical inline centrifugal pump with a fluorine-plastic lining designed for reliable, long-term handling of highly corrosive liquids. The pump combines a cast iron or cast steel casing with a fluorine-plastic inner lining to deliver excellent chemical resistance while retaining the mechanical strength of metallic components.

Key features

• Corrosion-resistant fluorine-plastic lining — protects the wet parts from acids, alkalis, oxidants and other aggressive media across a wide concentration range.
• Vertical inline configuration — inlet and outlet share the same centerline and diameter for compact, space-saving installation; optional protective cover enables outdoor installation.
• Efficient hydraulic design — developed from proven domestic hydraulic profiles and IS centrifugal-pump performance parameters to provide high hydraulic efficiency and energy savings.
• Directly mounted impeller — impeller is installed directly on the motor bearing for a short axial length and compact structure; pump/motor bearing arrangement balances radial and axial loads to reduce vibration and noise.
• Robust shaft sealing options — standard seals, abrasion-resistant mechanical seals, or combined mechanical seal arrangements to extend seal life in abrasive or corrosive services.
• Flexible deployment — pumps may be operated in series or parallel to meet required flow and head conditions.

Performance and operating conditions

• Suitable for pumping acids, alkalis, oxidizing liquids and other corrosive fluids at arbitrary concentrations.
• Service temperature range: approximately -85 °C to 200 °C (confirm for your application and local regulations).
• Designed to provide low noise, stable operation and reliable performance; often specified as a cost-effective alternative to pumps fabricated from 316L stainless steel or titanium alloys.

Typical industries and applications

• Chemical processing, petrochemical and refining
• Metallurgy and power generation
• Flue gas desulfurization and dust-removal systems
• Pulp & paper, textile and synthetic-fiber production
• Food and pharmaceutical process lines (where compatible with regulatory requirements)

Notes for specification and selection

• Verify the exact fluorine-plastic type, lining thickness and motor/impeller materials for compatibility with your fluid, temperature and pressure conditions.
• Select appropriate mechanical seal type and materials when solids, abrasives or severe oxidants are present.
• For series/parallel operation, confirm hydraulic curves and motor ratings to ensure stable combined operation.

Contact your technical sales or engineering representative with pump model (e.g., GDF40-160), required flow/head, operating temperature and fluid composition to obtain detailed performance curves and material certifications.
