Product Description
The FS-120mm is supplied for maintenance, overhaul and replacement work on compatible Flygt equipment. The selection is based on the FS-120 seal reference, 120 mm nominal size and the specified single / cartridge seal assembly.
Because one Flygt base model can have several hydraulic, motor or shaft configurations, the full model reference must be checked before ordering. The compatible variants shown on this page should be used together with the old seal dimensions, equipment nameplate and installation position.
Some listed variants use different shaft-end specifications, so the shaft-end size must be checked.
The 7×5, 8×5 or 9×5 configuration suffix is part of the seal-selection criteria.
Numerical suffixes after the base Flygt model are important because different variants can use different mechanical seals.
Flygt is a trademark of its respective owner. This product is an aftermarket replacement part supplied by Hong Teng and is not represented as an original Flygt product.
Application
- Upper mechanical seal replacement for the listed Flygt pump models
- Maintenance and overhaul of wastewater, drainage and industrial water pumping equipment where the dimensions and materials match
- Pump repair shops, maintenance contractors and OEM/private-label replacement projects based on model, sample or drawing
- Final suitability must be confirmed for the medium, temperature, pressure, speed, shaft end and installation position
