The compatibility list covers different Flygt equipment families, including pumps, compact mixers and motor-unit references. Do not select the FS-Q-U60 only from the 60 mm nominal size or a base family number.
Provide the complete equipment nameplate reference, numerical suffix, motor power or motor-unit version where applicable, upper seal position, photos of the removed seal and critical dimensions. Compatibility should be confirmed before shipment.
Product Description
The FS-Q-U60 Flygt mechanical seal is a 60 mm upper mechanical seal supplied for selected Flygt pumps, compact mixers and motor-unit configurations. Unlike a product page focused on one pump family, this replacement reference appears across several Flygt equipment groups, making complete equipment identification especially important.
Reference applications include Flygt 1335.181, selected 2250 and 2290 equipment, 3170 and 3201, the 4670 and 4680 compact mixers, selected 5100.230 and 5550 configurations, 600 Motor Unit references and selected 7045 and 7055.600 equipment.
The model number alone should not be treated as final confirmation. Variants within the same Flygt family may use different shaft, motor and seal arrangements. Always record the complete nameplate designation and determine whether the required component is the upper mechanical seal.
If the existing seal code is unknown, compare the old rotating and stationary components and record all critical dimensions. Our mechanical seal measurement guide explains how to measure a removed seal for replacement identification.
Because some FS-Q-U60 applications involve wastewater, slurry or mixed media, seal-face and elastomer selection should also be considered separately from dimensional compatibility. See our mechanical seal materials guide for wastewater and slurry pumps for additional material-selection considerations.
For other Flygt upper, lower and cartridge seal references, browse our Flygt replacement mechanical seals and identify the replacement using the complete equipment reference whenever possible.
Flygt names, trademarks and model references are used only to identify compatible applications. This FS-Q-U60 product is an independently manufactured aftermarket replacement mechanical seal supplied by Hong Teng and is not represented as an original Flygt product.

Important Notice
The FS-Q-U60 reference is used across several different Flygt equipment families. A 60 mm size, a base model number, or the visual appearance of the seal alone is not sufficient for final selection. Confirm the complete equipment reference and make sure the required component is the upper seal.
How to Confirm an FS-Q-U60 Replacement Seal
Use all of the following identification points together before ordering.
Record the Complete Equipment Model
Photograph the Flygt nameplate and record the full equipment reference, including numerical suffixes such as 1335.181, 5100.230 or 7055.600 where applicable.
Identify the Equipment Type
Confirm whether the seal is being selected for a pump, compact mixer or motor-unit configuration. For example, Flygt 4670 and 4680 are compact mixers rather than pump models.
Confirm the Upper Seal Position
FS-Q-U60 is an upper mechanical seal reference. Keep the upper and lower sealing components separated during removal and photograph their installed positions before disassembly whenever possible.
Check Dimensions, Motor Version & Materials
Confirm the nominal 60 mm size together with the old seal dimensions, motor power or motor-unit version where relevant, sealing-face materials and elastomers. Similar equipment may use different seal arrangements.
Original Flygt Sealing-System Reference
Xylem’s Flygt Active Seal documentation explains that selected Flygt products use double-seal systems with separate inner and outer mechanical seals or integrated Plug-in Seal arrangements. The official product-range reference includes Flygt 2250, 2290, 3170, 3201, 4670, 4680, 5100, 5550, 7045 and 7055 equipment.
This original technical information is provided only to explain the Flygt sealing-system concept and the importance of seal position. It does not identify the Hong Teng FS-Q-U60 replacement reference and should not be interpreted as a guaranteed material or performance specification for this product.
Frequently Asked Questions
Common questions about identifying and ordering an FS-Q-U60 upper mechanical seal.
What is the FS-Q-U60 Flygt mechanical seal?
The FS-Q-U60 is a 60 mm upper mechanical seal supplied by Hong Teng as an aftermarket replacement for selected Flygt pumps, compact mixers and motor-unit configurations.
Which Flygt equipment can use the FS-Q-U60 upper seal?
Reference applications include Flygt 1335.181, selected 2250, 2290, 3170 and 3201 variants, 4670 and 4680 compact mixers, selected 5100.230 and 5550 configurations, 600 Motor Unit references, and selected 7045 and 7055.600 equipment. Final compatibility should always be confirmed from the actual equipment and old seal.
Are Flygt 4670 and 4680 pumps?
No. Flygt 4670 and 4680 are compact mixer models. This is why FS-Q-U60 compatibility should be described as covering selected Flygt equipment rather than only pumps.
Is FS-Q-U60 an upper or lower mechanical seal?
FS-Q-U60 is an upper mechanical seal reference. Depending on the Flygt equipment configuration, the lower sealing component may use a different reference and should be identified separately.
Can I order the FS-Q-U60 using only the 60 mm size?
No. The 60 mm nominal size is only one identification parameter. The complete equipment model, numerical suffix, upper seal position, old seal design and relevant dimensions should also be checked.
Why is the motor-unit reference important?
Some Flygt replacement applications depend on motor-unit configuration or motor power rather than only the external pump or mixer family. When a motor-unit reference is available, include it together with the full equipment nameplate information.
What information should I send before ordering?
Please provide the full Flygt equipment model, numerical suffix, nameplate photo, motor-unit information where applicable, photos of the removed upper and lower seals, dimensions and required material information.
Is this an original Flygt mechanical seal?
No. The FS-Q-U60 shown here is an independently manufactured aftermarket replacement mechanical seal supplied by Hong Teng. Flygt trademarks and equipment references are used only for compatibility identification.
