Products Description
Water Pump F16 Water Seal – ID 16mm Mechanical Shaft Seal
Precision Sealing Solution for 16mm Pump Shafts
The F16 water seal is a mechanical shaft seal engineered for 16mm diameter pump shafts, designed to prevent fluid leakage at the critical point where the shaft exits the pump housing. This seal uses a combination of spring-loaded components and precision sealing faces to maintain a tight barrier while allowing the shaft to rotate freely. Available in multiple material configurations including NBR, FKM (Viton), and advanced silicon carbide (SiC) combinations, the F16 seal offers reliable performance across a wide temperature range from -20°C to over 200°C.
Technical Profiles & Materials
Precision 16mm Shaft Fit – Designed specifically for 16mm diameter pump shafts with outer diameters ranging from 26.9mm to 30mm, ensuring proper fitment in standard water pump housings.
High Temperature & Pressure Tolerance – Operates across temperatures from -20°C to 200°C+ and pressures up to 1.0 MPa (10 bar), suitable for both standard and heavy-duty water pumping applications.
Multiple Material Configurations – Available with carbon/ceramic, SiC/SiC, or carbon/SiC face combinations; elastomers including NBR, FKM (Viton), HNBR, and EPDM to match specific application requirements.
Spring-Loaded Design – Internal spring automatically adjusts sealing pressure to compensate for wear and maintain consistent seal integrity over extended service life.

Products Application
Agricultural Irrigation Pumps
The F16 16mm seal is a direct replacement for mechanical seals in 2-inch and 3-inch agricultural water pumps. Its robust construction handles the continuous operation and abrasive conditions typical of field irrigation, while the spring-loaded design maintains seal integrity during pressure fluctuations.
Pressure Washer & Cleaning Equipment
Suitable for high-pressure cleaning machines where the 16mm shaft seal prevents water leakage and maintains pump efficiency. The seal's corrosion-resistant materials withstand detergent exposure and frequent pressure cycling.
Industrial & Municipal Water Systems
Used in centrifugal pumps for water treatment, construction dewatering, and municipal water supply. The F16 seal's range of material options allows matching to specific fluid temperatures and chemical compatibility requirements.

FAQ
Q: How do I confirm this seal fits my pump?
A:Measure the shaft diameter (16mm) and housing bore (typically 27-30mm). The F16 seal is available with multiple outer diameter and length configurations; match your existing seal dimensions before ordering.
Q: What are the symptoms of a worn mechanical seal?
A:Common signs include visible water leakage from the pump shaft area, reduced pump pressure or flow, and noisy operation. Regular inspection and replacement at the first sign of leakage prevents more serious pump damage.
Q: What elastomer material should I choose?
A: NBR (nitrile) is suitable for standard water applications. FKM (Viton) offers superior chemical and heat resistance. EPDM provides excellent resistance to hot water and mild acids. HNBR offers the best combination of heat resistance and durability for heavy-duty applications.
