Product Description

Parameter Category	Specific Parameter	Detailed Description
Basic Information
Seal Type	QT-Lowara Mechanical Seal	A high - performance mechanical seal meticulously designed for Lowara pumps, ensuring optimal sealing efficiency and reliable operation across various industrial and commercial applications.
Brand	[Brand Name]
Model	QT-Lowara	This model is engineered to meet the demanding requirements of Lowara pump systems, providing consistent performance under different working conditions.
Materials
- Rotating Ring	Tungsten Carbide	Tungsten carbide offers outstanding hardness and wear resistance, enabling the rotating ring to endure high - speed and high - pressure operations with minimal wear, thus extending the overall lifespan of the seal.
- Stationary Ring	Carbon Graphite	Carbon graphite is utilized for the stationary ring due to its excellent self - lubricating properties and good chemical resistance, which contribute to smooth operation and effective sealing.
- O - Ring	Ethylene Propylene Diene Monomer (EPDM)	The EPDM O - ring provides a tight seal and is highly resistant to water, steam, and many common chemicals, ensuring reliable performance in diverse media environments.
Size Specifications
Shaft Diameter Range	12 - 45 mm	This seal is compatible with pump shafts having diameters within the 12 - 45 mm range, making it suitable for a wide variety of Lowara pump models.
Seal Chamber Inner Diameter	22 - 55 mm	Designed to fit precisely into seal chambers with inner diameters ranging from 22 - 55 mm, facilitating proper installation and ensuring a secure fit.
Seal Width	6.5 mm	The 6.5 mm seal width is optimized to strike a balance between achieving efficient sealing and minimizing frictional resistance, enhancing the seal's operational efficiency.
Performance Parameters
Working Pressure	Maximum 1.8 MPa	Under normal operating conditions, the QT-Lowara mechanical seal can withstand a maximum working pressure of 1.8 MPa, effectively preventing leakage of the pumped medium and maintaining system integrity.
Working Temperature	-30ºC - 130ºC	It is capable of operating effectively within a wide temperature range from -30ºC to 130ºC, making it suitable for applications in both cold - storage facilities and high - temperature industrial processes.
Linear Velocity	Maximum 12 m/s	The seal can handle a maximum linear velocity of 12 m/s, ensuring stable performance even when the pump is operating at high rotational speeds.
Applicable Media
- Water	Ideal for use with clean water, potable water, and wastewater, ensuring reliable sealing in water - related applications.
- Oil	Suitable for various types of lubricating oils, hydraulic oils, and mineral oils, providing effective sealing in oil - based systems.
- Chemical Solutions	Can be used with a range of chemical solutions, including weak acids and alkalis with pH values between 4 - 10, depending on the specific chemical composition and concentration.
Installation and Maintenance
Installation Method	Axial Installation	Installed axially onto the pump shaft following a standardized installation procedure. Proper alignment and positioning are crucial to ensure optimal sealing performance.
Installation Torque	12 - 18 N·m	During installation, an installation torque within the range of 12 - 18 N·m should be applied to secure the seal in place without causing damage to the seal components.
Maintenance Cycle	Every 4000 operating hours	Regular maintenance is recommended every 4000 operating hours. Maintenance tasks include inspecting the seal for signs of wear, leakage, and damage, as well as checking the alignment and tightness of related components.
Storage Conditions	Store in a dry, dust - free environment at a temperature between 5ºC - 25ºC. Keep away from direct sunlight, moisture, and corrosive substances.	Proper storage conditions help preserve the quality and performance of the seal components, preventing premature degradation and ensuring a longer shelf life.
Quality and Certification
Service Life	Approximately 2 - 3 years under normal operating conditions	With proper operation and regular maintenance, the QT-Lowara mechanical seal can provide reliable service for approximately 2 - 3 years, offering a cost - effective sealing solution.
Leakage Rate	≤0.05 mL/h	Engineered to have an extremely low leakage rate of ≤0.05 mL/h, ensuring minimal loss of the pumped medium and meeting strict environmental and operational requirements.
Certification Standards	ISO 9001, ISO 14001, and relevant industry standards	The seal complies with ISO 9001 quality management system standards and ISO 14001 environmental management system standards, as well as other applicable industry standards, guaranteeing high - quality performance and environmental sustainability.
Other Characteristics
Vibration Resistance	Can withstand vibrations with a frequency range of 3 - 50 Hz and an amplitude of 0.6 mm.	Designed to maintain its sealing performance even in environments with significant vibrations, ensuring stable operation of the pump system.
Self - lubricating Property	The seal surfaces are treated with a special self - lubricating coating, reducing friction and wear during operation.	This self - lubricating feature not only extends the service life of the seal but also reduces energy consumption and maintenance costs.
