QT XE Alumina 35mm Mechanical Seal for Flygt Pump
The QT XE Alumina 35mm mechanical seal is a replacement seal option for Flygt submersible pump service where an alumina ceramic sealing face is required. It is used in pump repair, wastewater pump maintenance, and replacement projects where the old seal must be matched by size, material, and installation structure.
Description:
Flygt submersible pumps are widely used in municipal wastewater, sewage transfer, drainage, and industrial water-handling systems. The mechanical seal protects the motor chamber and helps keep wastewater, oil, and external contaminants separated during pump operation. When the seal faces are worn, cracked, corroded, or installed with the wrong material, leakage and motor damage can happen quickly.

Why choose this QT XE Alumina seal
Material choice for suitable Flygt seal positions
Alumina ceramic is a practical face material for suitable Flygt pump sealing positions, especially where corrosion resistance and cost control are important. It should be selected according to actual liquid condition and seal position.
35 mm replacement option
The page is focused on the QT XE Alumina 35mm seal size. If the pump has been repaired before or the old seal is not original, the old seal dimensions should be checked before ordering.
Confirmation before quotation
Fluid Tech Service can confirm the replacement seal according to pump model, shaft size, old seal photos, drawings, or samples. This helps avoid wrong material selection and installation mismatch.
Options for different working conditions
FKM, NBR, EPDM, SS304, SS316, alumina ceramic, carbon graphite, tungsten carbide, and silicon carbide options can be discussed according to medium, temperature, corrosion, and solids content.

FAQ
Is this QT XE Alumina seal suitable for Flygt pumps?
Yes. This page is for a QT XE Alumina 35mm mechanical seal replacement used in Flygt pump service. Please send the pump model, old seal photos, or drawings for final confirmation.
What is the standard size of this seal?
The standard size listed for this product is 35 mm. If your pump has been repaired before, please confirm the old seal dimensions before ordering.
When should alumina ceramic be selected?
Alumina ceramic is commonly selected for clean oil-side or less abrasive sealing duties where corrosion resistance and cost control are important. For sewage-side abrasive conditions, tungsten carbide or silicon carbide may be better.
Can this seal be used for wastewater pumps?
Yes, it can be used in Flygt wastewater pump maintenance when the seal position and material are suitable. The exact material should be confirmed according to sewage condition, solids content, and installation position.
What information is needed for quotation?
Please provide pump model, shaft size, old seal photos, working medium, temperature, pressure, material requirement, quantity, and delivery requirement.
Can you make the seal according to a sample?
Yes. Fluid Tech Service can confirm and supply replacement mechanical seals according to old samples, photos, or drawings.
