Product Description

Parameter Category	Specific Parameter	Detailed Description
Basic Information
Seal Type	Queeny- Cartx QN Mechanical Seal	A high - performance mechanical seal designed for a wide range of industrial pumps, ensuring reliable sealing and long - term operation.
Brand	[Brand Name]
Model	Queeny- Cartx QN	This model is engineered to meet the demanding requirements of various fluid handling applications.
Materials
- Rotating Ring	Silicon Carbide (SiC)	SiC provides excellent hardness and wear resistance, enabling the rotating ring to withstand high - speed and high - pressure conditions, thus extending the seal's service life.
- Stationary Ring	Tungsten Carbide	Tungsten carbide offers superior strength and chemical resistance, ensuring a stable and efficient seal interface.
- O - Ring	Fluoroelastomer (FKM)	The FKM O - ring ensures a tight seal and is resistant to a broad range of chemicals and temperatures, guaranteeing reliable performance in diverse operating environments.
Size Specifications
Shaft Diameter Range	25 - 60 mm	Suitable for installation on pump shafts with diameters within this range, accommodating different pump sizes and configurations.
Seal Chamber Inner Diameter	35 - 70 mm	Designed to fit into seal chambers with inner diameters in this range, ensuring proper installation and optimal sealing performance.
Seal Width	9 mm	The 9 - mm seal width is optimized to balance effective sealing and minimal friction, enhancing the overall efficiency of the pump system.
Performance Parameters
Working Pressure	Maximum 2.0 MPa	Under normal operating conditions, the seal can withstand a maximum pressure of 2.0 MPa, preventing leakage of the pumped medium.
Working Temperature	-30ºC - 180ºC	Capable of operating effectively within this wide temperature range, making it suitable for both low - temperature and high - temperature industrial applications.
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 Fluids	Suitable for clean water, cooling water, and various water - based chemical solutions with a pH range of 2 - 13.
- Oil - based Fluids	Compatible with lubricating oils, gear oils, and most hydraulic oils.
- Chemicals	Resistant to common acids, alkalis, and solvents, but specific compatibility should be verified for certain chemicals.
Installation and Maintenance
Installation Method	Axial Installation	Installed axially onto the pump shaft following a precise installation procedure to ensure correct alignment and tight sealing.
Installation Torque	18 - 23 N·m	Apply a torque within this range during installation to securely fasten the seal without causing damage to the components.
Maintenance Cycle	Every 4000 operating hours	Regular maintenance is recommended every 4000 operating hours, including inspection for signs of wear, leakage, and proper component alignment.
Storage Conditions	Store in a dry, cool place with a temperature range of 5ºC - 25ºC. Keep away from direct sunlight, moisture, and corrosive gases.	Proper storage conditions help preserve the quality and integrity of the seal components, extending their shelf life.
Quality and Certification
Service Life	Approximately 2 - 4 years under normal operating conditions	With proper operation and maintenance, the Queeny- Cartx QN seal can provide reliable service for 2 - 4 years.
Leakage Rate	≤0.05 mL/h	Engineered to have an extremely low leakage rate, ensuring minimal loss of the pumped medium and meeting strict environmental and operational requirements.
Certification Standards	ISO 9001, ISO 14001, and industry - specific certifications (if applicable)	Meets international quality management and environmental management system standards, ensuring consistent product quality and environmental compliance.
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 significant vibration, ensuring stable pump operation.
Self - lubricating Property	The seal faces are coated with a special self - lubricating material, reducing friction and wear, and enhancing the seal's durability.	This self - lubricating feature minimizes the need for additional lubrication and extends the maintenance intervals.

• Low emission single seal - designed to satisfy U.S. federal, state and local regulatory requirements. Type 48 assures emission control with a single seal arrangement in VOC services. Years of low emission sealing are provided.
• Type 48 sealing package - Type 48 seals are application-specific with the proper selection of primary ring, mating ring materials and flush arrangement.
• Computer-optimized seal faces - computer modeling minimizes thermal and pressure caused distortion. For optimal performance, face materials are specified antimony filled carbon graphite versus silicon carbide as standard.
• Flush maximizes cooling - available with an extended flush with single point injection and a large percentage of the mating ring exposed to the process fluid for cooler running. For higher heat loads, a distributed flush with improved heat transfer characteristics is recommended.
