Product Description

Parameter Category	Specific Parameter	Detailed Description
Basic Information
Seal Type	Queeny-lowara Mechanical Seal	A specialized mechanical seal designed for Lowara pumps, ensuring stable and efficient sealing performance across diverse industrial applications.
Model	QL - 2025	This model is optimized for specific pump models within the Lowara range, providing reliable sealing solutions.
Materials
- Rotating Ring	Silicon Carbide (SiC)	The SiC rotating ring offers exceptional hardness and wear resistance, enabling it to withstand high - speed and high - pressure operations, thereby extending the seal's lifespan.
- Stationary Ring	Tungsten Carbide	Tungsten carbide stationary ring provides excellent corrosion resistance and a smooth surface for effective sealing, reducing friction between mating surfaces.
- O - Ring	Fluoroelastomer (FKM)	The FKM O - ring ensures a tight seal and is resistant to a wide variety of chemicals and temperatures, maintaining its integrity in different media environments.
Size Specifications
Shaft Diameter Range	18 - 45 mm	Suitable for pump shafts with diameters within this range, making it compatible with multiple Lowara pump models.
Seal Chamber Inner Diameter	28 - 55 mm	Designed to fit into seal chambers with inner diameters in this interval, guaranteeing proper installation and optimal sealing performance.
Seal Width	8.5 mm	The 8.5 mm width is carefully determined to balance effective sealing and reduced friction, enhancing the overall efficiency of the pumping system.
Performance Parameters
Working Pressure	Maximum 1.5 MPa	Under normal operating conditions, the Queeny - lowara seal can handle a maximum working pressure of 1.5 MPa, preventing leakage of the pumped fluid and ensuring system stability.
Working Temperature	- 20ºC - 130ºC	Capable of operating effectively within this temperature range, it can adapt to both cold and moderately high - temperature applications, suitable for various industrial processes.
Linear Velocity	Maximum 10 m/s	The seal is engineered to withstand a maximum linear velocity of 10 m/s, ensuring stable performance even when the pump operates at high speeds.
Applicable Media
- Water - based Fluids	Suitable for potable water, wastewater, and aqueous solutions with a pH range of 3 - 11. It can handle different water qualities and chemical compositions in water - based media.
- Oil - based Fluids	Compatible with common lubricating oils, hydraulic oils, and some light hydrocarbon oils, providing reliable sealing for oil - related pumping applications.
- Chemical Solutions	Resistant to many common chemical solutions, such as weak acids, alkalis, and certain solvents, making it suitable for chemical processing and handling tasks.
Installation and Maintenance
Installation Method	Axial Installation	Installed axially onto the pump shaft following a specific and precise installation procedure to ensure correct alignment and a secure seal.
Installation Torque	13 - 17 N·m	During installation, applying a torque within this range secures the seal in place without causing damage to the seal components.
Maintenance Cycle	Every 3500 operating hours	Regular maintenance is recommended every 3500 operating hours. This includes inspecting the seal for signs of wear, leakage, and proper alignment, and performing necessary adjustments or replacements.
Storage Conditions	Store in a dry, well - ventilated environment at a temperature between 5ºC - 28ºC. Keep away from direct sunlight, heat sources, and corrosive substances.	Proper storage conditions help maintain the quality and integrity of the seal components, ensuring their optimal performance when installed.
Quality and Certification
Service Life	Approximately 1.8 - 2.8 years under normal operating conditions	With proper operation and maintenance, the Queeny - lowara mechanical seal can provide reliable service for 1.8 to 2.8 years, reducing the frequency of replacements.
Leakage Rate	≤0.09 mL/h	The seal is designed to have an extremely low leakage rate, minimizing the risk of fluid loss and environmental contamination.
Certification Standards	ISO 9001, ISO 14001	Meets the requirements of ISO 9001 quality management system standards and ISO 14001 environmental management system standards, demonstrating its high - quality and environmental - friendly features.
Other Characteristics
Vibration Resistance	Can withstand vibrations with a frequency range of 5 - 45 Hz and an amplitude of 0.45 mm.	Engineered to maintain its sealing performance even in environments with moderate vibration levels, ensuring stable operation of the pumping system.
Self - lubricating Property	The seal surfaces are coated with a self - lubricating material to reduce friction and wear.	This self - lubricating feature not only extends the service life of the seal but also improves the energy efficiency of the pumping system.
