| Seal Chamber Inner Diameter |
28 - 55 mm |
Designed to fit into seal chambers with inner diameters from 28 to 55 mm, ensuring proper installation and optimal sealing performance. |
| Seal Width |
8.5 mm |
The 8.5 mm seal width is optimized to balance sealing effectiveness and minimize frictional losses, contributing to the overall efficiency of the pumping system. |
| Performance Parameters |
|
|
| Working Pressure |
Maximum 1.5 MPa |
Under normal operating conditions, the Queeny - MQC seal can withstand a maximum working pressure of 1.5 MPa, preventing fluid leakage and maintaining system integrity. |
| Working Temperature |
-20ºC - 130ºC |
Capable of operating efficiently within this temperature range, it can adapt to both cold - start conditions and moderately high - temperature processes, making it versatile for different applications. |
| Linear Velocity |
Maximum 10 m/s |
The seal is engineered to handle a maximum linear velocity of 10 m/s, ensuring stable performance even when the pump is running at high rotational speeds. |
| Applicable Media |
|
|
| - Water - based Fluids |
Suitable for potable water, cooling water, and various water - based chemical solutions with a pH range of 3 - 11. It can handle both slightly acidic and alkaline water - based media. |
|
| - Oil - based Fluids |
Compatible with common lubricating oils, hydraulic oils, and some fuel oils. It provides reliable sealing for oil - circulation systems in machinery and equipment. |
|
| - Chemical Solutions |
Resistant to many common industrial chemicals, such as alcohols, ketones, and some weak acids and alkalis, making it suitable for chemical processing and pharmaceutical applications. |
|
| Installation and Maintenance |
|
|
| Installation Method |
Axial Installation |
The seal is installed axially onto the pump shaft. A specific installation procedure must be followed to ensure correct alignment, proper compression of the O - ring, and a secure seal. |
| Installation Torque |
13 - 17 N·m |
During installation, applying a torque within the 13 - 17 N·m range secures the seal without over - tightening, which could damage the seal components. |
| Maintenance Cycle |
Every 3500 operating hours |
Regular maintenance every 3500 operating hours is recommended. This includes visual inspection for signs of leakage, wear on the seal faces, and proper alignment of the seal components. |
| Storage Conditions |
Store in a dry, dark environment at a temperature between 0ºC - 30ºC. Keep away from corrosive gases and direct contact with other chemicals. |
Proper storage preserves the integrity of the seal materials, ensuring they are in optimal condition when ready for installation. |
| Quality and Certification |
|
|
| Service Life |
Approximately 1.8 - 2.8 years under normal operating conditions |
With proper operation and regular maintenance, the Queeny - MQC seal can provide reliable service for 1.8 to 2.8 years, reducing maintenance costs and downtime. |
| Leakage Rate |
≤0.09 mL/h |
Engineered to have a low leakage rate, the seal minimizes the risk of fluid loss and environmental contamination, ensuring safe and efficient operation of the pumping system. |
| Certification Standards |
ISO 9001, ISO 14001 |
The Queeny - MQC seal complies with ISO 9001 quality management system standards and ISO 14001 environmental management system standards, reflecting its high - quality manufacturing and environmental responsibility. |
| Other Characteristics |
|
|
| Vibration Resistance |
Can withstand vibrations with a frequency range of 5 - 45 Hz and an amplitude of 0.45 mm |
Designed to maintain its sealing performance in environments with moderate vibration levels, ensuring stable operation of the pumping system in various industrial settings. |
| Self - lubricating Property |
The seal faces have a self - lubricating design, reducing friction between the rotating and stationary rings. |
This self - lubricating feature not only extends the service life of the seal but also improves the overall efficiency of the pumping system by reducing energy consumption due to friction. |
