Product Description
The SYKES-40 Mechanical Seal is a 40mm replacement sealing solution developed for selected Sykes pump applications. The seal uses a balanced multi-spring construction designed to provide stable sealing performance in demanding dewatering, drainage and industrial pumping environments.
The mechanical seal assembly consists of a rotating seal unit and a separate stationary seat, providing a compact and serviceable design for pump maintenance and overhaul. Wear-resistant seal face materials are available for applications where pumps operate with water containing suspended solids, abrasive particles or other challenging media.
Selected Sykes contractor pump models use 40mm shaft arrangements and balanced multi-spring mechanical seals. Depending on the specific pump configuration, silicon carbide sealing faces can be supplied to provide excellent wear resistance and reliable performance under continuous operating conditions.
Main Features
- SYKES-40 replacement mechanical seal
- 40mm shaft size
- Balanced multi-spring seal design
- Separate rotating unit and stationary seal seat
- Silicon carbide seal face options
- Stainless-steel metal components
- Suitable for demanding dewatering pump service
- Designed for pump repair and maintenance replacement
- Different elastomer materials available according to the pumped medium

The SYKES-40 seal is manufactured by Hong Teng as an aftermarket replacement mechanical seal and is not an original Sykes product. Because pump configurations may vary even when the shaft diameter is the same, customers should confirm the pump model, seal dimensions and operating conditions before ordering.
Application
The SYKES-40 40mm Mechanical Seal is designed for selected Sykes pump applications used in dewatering, construction, mining, wastewater handling and general industrial pumping systems.
- Sykes dewatering pumps
- Sykes contractor pumps
- Self-priming centrifugal pumps
- Construction site dewatering systems
- Mining dewatering pumps
- Industrial drainage systems
- Municipal and utility pumping applications
- Water transfer equipment

- Pump repair and overhaul applications
Selected 40mm-shaft Sykes pump families include models in the CP80, CP100 and CP150 ranges. Exact compatibility should be confirmed according to the original mechanical seal dimensions, pump model and installation arrangement before replacement.
For abrasive water, wastewater or demanding industrial service, suitable seal face and elastomer materials should be selected according to the actual pumped medium, temperature and operating conditions.
