Product Description

Parameter Category	Specific Parameter	Detailed Description
Basic Information
Seal Type	QT CR Mechanical Seal	A high - performance mechanical seal designed for industrial pumps, providing reliable leakage prevention and long - term operation stability.
Brand	[Brand Name]
Model	QT CR	This model is engineered to meet the demanding requirements of various industrial applications.
Materials
- Rotating Ring	Tungsten Carbide	Tungsten carbide offers extreme hardness and wear resistance, ensuring the rotating ring can endure harsh operating conditions, such as high - speed rotation and heavy - duty workloads.
- Stationary Ring	Carbon Graphite	Carbon graphite provides excellent self - lubricating properties and low friction, which is beneficial for smooth sealing and reducing energy consumption.
- O - Ring	Ethylene - Propylene Diene Monomer (EPDM)	EPDM O - ring offers good resistance to water, steam, and many chemicals, and can maintain flexibility over a wide temperature range.
Size Specifications
Shaft Diameter Range	25 - 60 mm	Suitable for installation on pump shafts with diameters within this range, making it adaptable to different pump models.
Seal Chamber Inner Diameter	35 - 70 mm	Designed to fit into seal chambers with inner diameters in this range, ensuring a proper and secure installation.
Seal Width	9 mm	The 9 - mm width of the seal is optimized to balance sealing effectiveness and mechanical strength, reducing the risk of failure under pressure.
Performance Parameters
Working Pressure	Maximum 2.0 MPa	Under normal operation, the seal can withstand a maximum pressure of 2.0 MPa, effectively preventing medium leakage.
Working Temperature	-30ºC - 180ºC	Capable of operating efficiently within this wide temperature range, suitable for both extremely cold and high - temperature industrial environments.
Linear Velocity	Maximum 12 m/s	It can handle a maximum linear velocity of 12 m/s, ensuring stable sealing performance even in high - speed rotating pumps.
Applicable Media
- Water - based Fluids	Ideal for clean water, coolant solutions, and water - based chemical mixtures with a pH range of 4 - 10.
- Oil - based Fluids	Suitable for mineral oils, synthetic lubricants, and some non - aggressive oil - based media.
- Gas - based Media	Can be used in applications involving non - corrosive gases, such as air and nitrogen.
Installation and Maintenance
Installation Method	Axial Installation	Installed axially onto the pump shaft. A precise installation procedure must be followed to ensure correct alignment and tightness.
Installation Torque	18 - 22 N·m	During installation, a torque within this range should be applied to secure the seal properly without causing damage to the components.
Maintenance Cycle	Every 4000 operating hours	Regular maintenance every 4000 hours is recommended, including inspection for wear, leakage, and proper alignment of the seal components.
Storage Conditions	Store in a dry, dust - free environment at a temperature of 5ºC - 25ºC. Avoid exposure to sunlight and chemicals.	Proper storage conditions help preserve the quality and performance of the seal, extending its shelf life.
Quality and Certification
Service Life	Approximately 2 - 3.5 years under normal operating conditions	With proper operation and maintenance, the QT CR seal can provide reliable service for 2 to 3.5 years.
Leakage Rate	≤0.05 mL/h	Engineered to have an extremely low leakage rate, ensuring high - level containment of the pumped medium.
Certification Standards	ISO 9001, ISO 14001	Complies with international quality management (ISO 9001) and environmental management (ISO 14001) standards, guaranteeing product quality and environmental friendliness.
Other Characteristics
Vibration Resistance	Can withstand vibrations with a frequency range of 10 - 60 Hz and an amplitude of 0.6 mm.	Designed to maintain sealing integrity in environments with significant vibration, common in industrial settings.
Self - aligning Ability	The seal has a certain self - aligning capability, which helps compensate for minor misalignments between the shaft and the seal chamber, reducing installation difficulty and potential failure risks.

Queeny design engineers are able to produce a seals solution for the most basic applications,to those that are extremely complicated and unique. We are able to provide you these solutions supported by life test data and years of excellent field performance.As your partner, we provide sealing solutions for centrifugal pumps,agitators and other rotating equipment, and help you consolidate your brand and market position.
