We supply a complete range of high-performance replacement mechanical seals for Flygt submersible pumps, engineered to enhance reliability, reduce downtime, and lower total life‑cycle cost.
Our Flygt‑type plug-in cartridge seals combine the upper and lower seals in a single compact assembly for quick, accurate, and error-free installation. The robust metallic construction with moulded elastomer components offers excellent resistance to wear, misalignment, and vibration in demanding wastewater, slurry, and industrial applications.
- Pump model coverage
These replacement seals are suitable for a wide range of Flygt pump series, including many models in the 2000, 3000, and 3000‑series submersible lines. Typical shaft sizes match popular models such as 2066, 2075, 2101, 2151, 2250, 3041, 3068, 3085, 3102, 3140, 3152, 3171, 3201, and 3300, among others; specific upper and lower seal codes can be selected on request for your exact pump type and duty.

If you share your Flygt pump model and operating conditions, our engineering team will recommend the most suitable face and elastomer combination to maximise seal life and protect your equipment. Whether your plant handles municipal sewage, construction dewatering, or abrasive slurry, we can propose a configuration that balances performance, cost, and maintainability for your operation.
Features:
- Direction-independent operation, so the seal works reliably regardless of shaft rotation direction.
- Available in single and double seal arrangements to match standard, abrasive, or highly demanding services.
- Quick installation and easy removal, with no special tools required, minimising downtime during routine maintenance.
- Shaft sizes: 15.0, 20.0, 22.0, 25.0, 28.0, 35.0, 45.0, 60.0, 80.0, 90.0, and 120.0 mm to cover the most widely used Flygt pump ranges.
- Hydraulically balanced sealing faces (with unbalanced options where appropriate) for low leakage and longer face life at higher pressures.
- Internally mounted construction specifically engineered for Flygt submersible pumps, protecting critical parts from external contamination.
- Self-aligning, vibration-tolerant design that maintains face contact and sealing integrity under misalignment and fluctuating operating conditions.
- Plug-in cartridge design with upper and lower seals combined in a single, ready-to-install unit, eliminating setting errors and reducing assembly time.
Specification:
| Application | Suitable for services involving clean water, lightly and highly abrasive slurries, and corrosive process media. Typical applications include pulp and paper mills, chemical and petrochemical plants, steel and metal processing facilities, water and wastewater treatment plants, and municipal or industrial sewage systems. The seals are also well-suited for crystallising fluids and suspensions with low solids content, as well as for submersible sewage and dewatering duties in construction and infrastructure projects. | |
