Detailed Description
|
|
Basic Information
|
|
|
|
Seal Type
|
QT GLF-A Mechanical Seal
|
A high - performance mechanical seal designed for a wide range of industrial pump applications, ensuring reliable operation and efficient sealing.
|
|

|
|
|
Model
|
QT GLF-A
|
This model is engineered to meet the demanding requirements of various fluid handling systems.
|
|
Materials
|
|
|
|
- Rotating Ring
|
Tungsten Carbide
|
Tungsten carbide offers extremely high hardness and wear resistance, enabling the rotating ring to perform well under heavy loads and high - speed rotations.
|
|
- Stationary Ring
|
Carbon Graphite
|
Carbon graphite provides excellent self - lubricating properties and good compatibility with various media, reducing friction and wear on the seal faces.
|
|
- O - Ring
|
Ethylene Propylene Diene Monomer (EPDM)
|
EPDM O - ring ensures a tight seal and is highly resistant to water, steam, and many polar substances, suitable for a variety of working environments.
|
|
Size Specifications
|
|
|
|
Shaft Diameter Range
|
12 - 35 mm
|
The seal can be installed on shafts with diameters within this range, making it adaptable to different pump shaft sizes in industrial settings.
|
|
Seal Chamber Inner Diameter
|
20 - 45 mm
|
Designed to fit into seal chambers with inner diameters in this range for proper installation and optimal sealing performance.
|
|
Seal Width
|
6.5 mm
|
The 6.5 - mm width of the seal is carefully designed to balance sealing effectiveness and energy consumption, minimizing friction while maintaining a secure seal.
|
|
Performance Parameters
|
|
|
|
Working Pressure
|
Maximum 1.5 MPa
|
Under normal operating conditions, the QT GLF-A seal can withstand a maximum pressure of 1.5 MPa, preventing leakage of the pumped medium.
|
|
Working Temperature
|
-30ºC - 130ºC
|
It can operate efficiently within this wide temperature range, making it suitable for applications in cold storage facilities as well as moderately high - temperature industrial processes.
|
|
Linear Velocity
|
Maximum 9 m/s
|
The seal is capable of handling a maximum linear velocity of 9 m/s, ensuring stable performance even when the pump is running at high speeds.
|
|
Applicable Media
|
|
|
|
- Water - based Fluids
|
Ideal for clean water, coolant solutions, and slightly acidic or alkaline water - based media with a pH range of 4 - 10.
|
|
|
- Oil - based Fluids
|
Compatible with mineral oils, vegetable oils, and some synthetic lubricating oils.
|
|
|
- Other Fluids
|
Can be used with some non - aggressive chemical solutions, such as certain alcohol - based solvents.
|
|
|
Installation and Maintenance
|
|
|
|
Installation Method
|
Axial Installation
|
Installed axially onto the pump shaft following a standardized installation procedure to ensure proper alignment and sealing integrity.
|
|
Installation Torque
|
8 - 12 N·m
|
During installation, a torque within this range should be applied to secure the seal firmly without causing damage to the seal components.
|
|
Maintenance Cycle
|
Every 2500 operating hours
|
Regular maintenance is recommended every 2500 operating hours, including visual inspection of the seal for signs of wear, leakage, and damage, as well as checking the alignment of the seal components.
|
|
Storage Conditions
|
Store in a dry, dust - free environment at a temperature between 5ºC - 25ºC. Avoid exposure to direct sunlight and strong oxidizing agents.
|
Proper storage conditions help preserve the quality and performance of the seal, extending its shelf life.
|
|
Quality and Certification
|
|
|
|
Service Life
|
Approximately 1.8 - 2.2 years under normal operating conditions
|
With proper operation and regular maintenance, the QT GLF-A seal can provide reliable service for 1.8 to 2.2 years.
|
|
Leakage Rate
|
≤0.06 mL/h
|
Engineered to have an extremely low leakage rate, ensuring minimal loss of the pumped medium and maintaining the efficiency of the fluid handling system.
|
|
Certification Standards
|
ISO 9001, ISO 14001
|
The seal complies with international quality management (ISO 9001) and environmental management (ISO 14001) standards, guaranteeing high - quality production and environmental - friendly manufacturing processes.
|
|
Other Characteristics
|
|
|
|
Vibration Resistance
|
Can withstand vibrations with a frequency range of 3 - 35 Hz and an amplitude of 0.3 mm.
|
Designed to maintain its sealing performance even in environments with significant vibrations, ensuring stable operation of the pump.
|
|
Self - lubricating Property
|
The combination of carbon graphite stationary ring and the design of the seal faces provides self - lubricating capabilities, reducing the need for additional lubrication and extending the seal's service life.
