|
|
Model
|
QT - GLF
|
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 withstand high - speed and high - pressure operations, ensuring a long service life.
|
|
- Stationary Ring
|
Silicon Nitride
|
Silicon nitride provides excellent corrosion resistance and a smooth surface finish, which is crucial for maintaining a tight seal and reducing friction.
|
|
- O - Ring
|
Fluoroelastomer (FKM)
|
The FKM O - ring ensures a secure seal and is resistant to a broad spectrum of chemicals and temperature variations, guaranteeing consistent performance.
|
|
Size Specifications
|
|
|
|
Shaft Diameter Range
|
12 - 35 mm
|
Suitable for installation on shafts with diameters within this range, making it compatible with numerous pump models.
|
|
Seal Chamber Inner Diameter
|
22 - 45 mm
|
Specifically designed to fit into seal chambers with inner diameters in this interval, ensuring proper installation and operation.
|
|
Seal Width
|
6.5 mm
|
The 6.5 mm width is optimized to balance sealing effectiveness and minimize frictional losses, enhancing overall efficiency.
|
|
Performance Parameters
|
|
|
|
Working Pressure
|
Maximum 1.8 MPa
|
Under normal operating conditions, the QT - GLF seal can endure a maximum pressure of 1.8 MPa, effectively preventing the leakage of pumped media.
|
|
Working Temperature
|
- 25ºC - 130ºC
|
Capable of operating efficiently within this wide temperature range, suitable for both low - temperature and moderately high - temperature industrial applications.
|
|
Linear Velocity
|
Maximum 9 m/s
|
It can handle a maximum linear velocity of 9 m/s, ensuring stable sealing performance even in high - speed rotating pumps.
|
|
Applicable Media
|
|
|
|
- Water - based Fluids
|
Suitable for clean water, process water, and water - based solutions with a pH range of 2 - 12, including mildly acidic and alkaline liquids.
|
|
|
- Oil - based Fluids
|
Compatible with lubricating oils, gear oils, and some synthetic oil - based fluids commonly used in industrial machinery.
|
|
|
- Chemical Fluids
|
Resistant to many common chemicals such as alcohols, ketones, and esters, but it's recommended to check compatibility for specific chemicals.
|
|
|
Installation and Maintenance
|
|
|
|
Installation Method
|
Axial Installation
|
Installed axially onto the pump shaft following a precise installation procedure to ensure correct alignment and optimal sealing performance.
|
|
Installation Torque
|
12 - 17 N·m
|
During installation, a torque within this range should be applied to securely fasten the seal without causing damage to the components.
|
|
Maintenance Cycle
|
Every 4000 operating hours
|
Regular maintenance every 4000 operating hours is advised, including inspection for signs of wear, leakage, and proper functioning of the seal components.
|
|
Storage Conditions
|
Store in a dry, well - ventilated area at a temperature between 5ºC - 25ºC. Keep away from direct sunlight, moisture, and corrosive substances.
|
Proper storage conditions help preserve the integrity of the seal materials and extend its shelf life.
|
|
Quality and Certification
|
|
|
|
Service Life
|
Approximately 2 - 3 years under normal operating conditions
|
With proper operation and maintenance, the QT - GLF seal can provide reliable service for 2 - 3 years.
|
|
Leakage Rate
|
≤0.06 mL/h
|
Engineered to have an extremely low leakage rate, ensuring minimal loss of the pumped fluid and maintaining system efficiency.
|
|
Certification Standards
|
ISO 9001, ISO 14001
|
Complies with international quality management (ISO 9001) and environmental management (ISO 14001) standards, ensuring high - quality production and environmental sustainability.
|
|
Other Characteristics
|
|
|
|
Vibration Resistance
|
Can withstand vibrations with a frequency range of 4 - 45 Hz and an amplitude of 0.35 mm.
|
Designed to maintain its sealing integrity even in environments with moderate vibration levels, reducing the risk of leakage due to vibration.
|
|
Self - lubricating Property
|
The seal surfaces are treated with a special self - lubricating coating, reducing friction and wear, and minimizing the need for additional lubrication.
|
This self - lubricating feature enhances the seal's durability and reduces maintenance requirements.
