FLOWSERVE Precision Machined Oil Resistant Flow Pump Spare Parts Flange Gasket

Our brand delivers complete technical solutions within the fluid machinery and engineering sectors. Through our range of specialized technologies and product brands, we equip our clients with high-level technical advisory, commercial support, and integrated product solutions — covering pumps, frequency converters, servo drives, PLC-HMI, industrial control cabinets, motors, mechanical seals and assemblies, couplings, gearboxes, and turnkey engineering services (overseas on-site 3D scanning reverse molding of pump replacement parts and equipment debugging by our engineers deployed overseas).

FLOWSERVE Flange Gasket is a precision sealing component installed between pump flange faces to prevent fluid leakage at the joint interface. Flange gaskets in centrifugal pumps must maintain a reliable seal under varying pressures, temperatures, and fluid media — from clean water to abrasive slurry and corrosive process fluids.

Common failure modes include compression set (gasket loses spring-back ability), chemical attack from the process medium, thermal degradation, and erosion from high-velocity fluids. When a gasket fails, the result is leak paths at the flange joint, fluid loss, safety risk, and potential environmental contamination.

Our replacement flange gaskets are manufactured to exact OEM dimensions and material specifications, ensuring perfect fit and sealing performance. Custom gasket profiles — including spiral wound, ring joint (RTJ), and flat gasket designs — are available for non-standard pump models and high-pressure applications.

Material selection for flange gaskets must account for pressure rating, temperature, and fluid compatibility:

• Exact OEM Fit — Reverse-engineered to match original flange dimensions, bolt pattern, and gasket seating geometry; no re-machining of flange faces required
• Full Material Range — Cast iron, duplex stainless steel, alloy steel, and specialty alloys available to match your specific service conditions
• High-Pressure Capability — Spiral wound and ring joint designs rated for high-pressure pump flanges per ASME B16.5 and API standards
• Corrosion & Erosion Resistance — Material selection guided by fluid analysis; surface treatments available for aggressive media
• Rapid Reverse-Engineering — FARO 3D scanning captures gasket geometry from a sample; no original drawings required
• Quality Verified — Every gasket inspected for dimensional accuracy, material certification, and surface finish before shipment
