|
Size Specifications
|
|
|
|
Shaft Diameter Range
|
25 - 55 mm
|
This seal is compatible with pump shafts within the 25 - 55 mm diameter range, making it suitable for numerous pump models and sizes.
|
|
Seal Chamber Inner Diameter
|
35 - 65 mm
|
Specifically designed to fit into seal chambers with inner diameters in the 35 - 65 mm range, ensuring proper installation and optimal sealing.
|
|
Seal Width
|
9 mm
|
The 9 mm seal width is carefully optimized to strike a balance between achieving a tight seal and minimizing energy consumption due to friction.

|
Performance Parameters
|
|
|
|
Working Pressure
|
Maximum 2.0 MPa
|
Under normal operating circumstances, the QT-VC-85 seal can withstand a maximum pressure of 2.0 MPa, effectively preventing the leakage of the pumped medium.
|
|
Working Temperature
|
-30ºC - 180ºC
|
It is capable of operating efficiently within a wide temperature range from -30ºC to 180ºC, adapting well to both extremely cold and high-temperature industrial environments.
|
|
Linear Velocity
|
Maximum 12 m/s
|
The seal can handle a maximum linear velocity of 12 m/s, ensuring stable performance even in high-speed rotating pumps.
|
|
Applicable Media
|
|
|
|
- Water-based Solutions
|
Ideal for use with clean water, deionized water, and various aqueous solutions with pH values ranging from 2 to 13.
|
|
|
- Oil-based Fluids
|
Suitable for lubricating oils, gear oils, and most common hydraulic oils.
|
|
|
- Chemical Liquids
|
Resistant to mild acids, alkalis, and some organic solvents, but specific compatibility should be verified based on the actual chemical composition.
|
|
|
Installation and Maintenance
|
|
|
|
Installation Method
|
Axial Installation
|
The seal is installed axially onto the pump shaft following a precise installation procedure. This ensures correct alignment and proper seating for maximum sealing effectiveness.
|
|
Installation Torque
|
18 - 22 N·m
|
During installation, an installation torque within the 18 - 22 N·m range should be applied to secure the seal firmly without causing damage to its components.
|
|
Maintenance Cycle
|
Every 4000 operating hours
|
Regular maintenance is recommended every 4000 operating hours. This includes inspecting the seal for signs of wear, checking for any leakage, and ensuring proper alignment.
|
|
Storage Conditions
|
Store in a dry, cool place with a temperature range of 5ºC - 25ºC. Keep away from direct sunlight, humidity, and corrosive substances.
|
Proper storage conditions are essential to maintain the integrity of the seal materials and prevent premature degradation.
|
|
Quality and Certification
|
|
|
|
Service Life
|
Approximately 2 - 3.5 years under normal operating conditions
|
With proper operation and regular maintenance, the QT-VC-85 seal can provide reliable service for 2 to 3.5 years.
|
|
Leakage Rate
|
≤0.12 mL/h
|
Engineered to have a low leakage rate, the seal ensures that the pumped medium remains contained within the system, minimizing waste and potential safety hazards.
|
|
Certification Standards
|
ISO 9001, ISO 14001, and API 682 (if applicable)
|
The seal complies with international quality management standards (ISO 9001), environmental management standards (ISO 14001), and may also meet the requirements of API 682 depending on the specific application.
|
|
Other Characteristics
|
|
|
|
Vibration Resistance
|
Can withstand vibrations with a frequency range of 8 - 60 Hz and an amplitude of 0.6 mm.
|
Designed to maintain its sealing performance in environments with moderate to high levels of vibration, ensuring stable operation of the pump.
|
|
Self-lubricating Feature
|
The contact surfaces of the seal are treated with a special coating to enhance self-lubrication.
|
This self-lubricating feature reduces friction, minimizes wear, and extends the overall service life of the seal.
