The FKM O - ring ensures a tight seal and is resistant to a wide range of chemicals and temperatures, maintaining its integrity in different media environments. |
| Size Specifications |
|
|
| Shaft Diameter Range |
18 - 45 mm |
This seal is compatible with pump shafts having diameters within this range, making it suitable for a diverse array of pump models. |
| Seal Chamber Inner Diameter |
28 - 55 mm |
Designed to fit snugly into seal chambers with inner diameters in this interval, guaranteeing proper installation and optimal sealing performance. |
| Seal Width |
8.5 mm |
The 8.5 mm width of the seal is optimized to balance efficient sealing and reduced frictional forces, enhancing the overall efficiency of the pumping system. |
| Performance Parameters |
|
|
| Working Pressure |
Maximum 1.5 MPa |
Under normal operating conditions, the QT - Type2 seal can handle a maximum working pressure of 1.5 MPa, preventing leakage of the pumped fluid and maintaining system stability. |
| Working Temperature |
-20ºC - 130ºC |
Capable of operating effectively within this temperature range, it can adapt to both cold - and high - temperature applications, making it suitable for various industrial processes. |
| Linear Velocity |
Maximum 10 m/s |
The seal is engineered to withstand a maximum linear velocity of 10 m/s, ensuring consistent performance even at relatively high rotational speeds. |
| Applicable Media |
|
|
| - Water - based Fluids |
Suitable for clean water, treated water, and water - based solutions with a pH range of 4 - 10. It can handle both slightly acidic and alkaline water - based media. |
|
| - Oil - based Fluids |
Compatible with common lubricating oils, hydraulic oils, and some light - viscosity oil - based fluids, providing reliable sealing for oil - handling systems. |
|
| - Chemical Solutions |
Resistant to many common chemical solutions, such as weak acids, alkalis, and some organic solvents, making it suitable for chemical processing applications. |
|
| Installation and Maintenance |
|
|
| Installation Method |
Axial Installation |
The seal is installed axially onto the pump shaft following a standardized installation procedure to ensure proper alignment and a secure seal. |
| Installation Torque |
13 - 17 N·m |
During installation, a torque within this range should be applied to secure the seal firmly in place without causing damage to the seal components. |
| Maintenance Cycle |
Every 3500 operating hours |
Regular maintenance is recommended every 3500 operating hours. This includes inspecting the seal for signs of wear, leakage, and proper alignment, and performing any necessary adjustments or replacements. |
| Storage Conditions |
Store in a dry, shaded environment at a temperature between 8ºC - 22ºC. Keep away from direct sunlight, moisture, and corrosive substances. |
Proper storage conditions help preserve the quality and integrity of the seal components, ensuring their optimal performance when installed. |
| Quality and Certification |
|
|
| Service Life |
Approximately 1.8 - 2.8 years under normal operating conditions |
With proper operation and maintenance, the QT - Type2 mechanical seal can provide reliable service for 1.8 to 2.8 years, reducing downtime and replacement costs. |
| Leakage Rate |
≤0.09 mL/h |
The seal is designed to have a low leakage rate, ensuring that the pumped fluid remains within the system, minimizing product loss and environmental risks. |
| Certification Standards |
ISO 9001, ISO 14001 |
The QT - Type2 seal complies with ISO 9001 quality management system standards and ISO 14001 environmental management system standards, reflecting its high - quality and environmentally friendly design. |
| Other Characteristics |
|
|
| Vibration Resistance |
Can withstand vibrations with a frequency range of 6 - 45 Hz and an amplitude of 0.45 mm. |
Engineered to maintain its sealing performance in environments with moderate vibration levels, ensuring stable operation of the pumping equipment. |
| Self - lubricating Property |
The seal faces are coated with a self - lubricating material to reduce friction and wear. |
This self - lubricating feature extends the service life of the seal and improves the energy efficiency of the pumping system by minimizing frictional losses. |
