Product Description

Parameter Category	Specific Parameter	Detailed Description
Basic Information
Seal Type	QT-EVMS Mechanical Seal	A high-performance mechanical seal designed for various industrial pumps, providing reliable sealing solutions.
Model	QT-EVMS	Specifically engineered to meet the demands of diverse operating conditions.
Materials
- Rotating Ring	Tungsten Carbide	Tungsten carbide offers excellent hardness and wear resistance, enabling the rotating ring to endure high-speed and high-pressure operations, thus extending the seal's lifespan.
- Stationary Ring	Carbon Graphite	Carbon graphite provides good self-lubricating properties and low friction, ensuring efficient sealing and reducing wear on mating surfaces.
- O-Ring	Fluoroelastomer (FKM)	The FKM O-ring ensures a tight seal and demonstrates high resistance to a wide range of chemicals and temperatures, guaranteeing reliable performance.
Size Specifications
Shaft Diameter Range	25 - 60 mm	This seal is compatible with pump shafts within this diameter range, making it suitable for numerous pump models.
Seal Chamber Inner Diameter	35 - 70 mm	Designed to fit precisely into seal chambers with inner diameters in this range, ensuring proper installation and optimal operation.
Seal Width	10 mm	The 10 mm width is carefully selected to strike a balance between effective sealing and minimizing frictional losses.
Performance Parameters
Working Pressure	Maximum 2.0 MPa	Under normal operating conditions, the seal can withstand a maximum pressure of 2.0 MPa, effectively preventing the leakage of pumped media.
Working Temperature	-25ºC - 180ºC	Capable of operating efficiently within this wide temperature range, making it suitable for both low-temperature and high-temperature applications.
Linear Velocity	Maximum 12 m/s	The seal can handle a maximum linear velocity of 12 m/s, ensuring stable performance even at high rotational speeds.
Applicable Media
- Water-based Fluids	Suitable for pure water, process water, and various aqueous solutions with a pH range of 2 - 13.
- Oil-based Fluids	Applicable to mineral oils, synthetic lubricants, and some light petroleum-based fluids.
- Chemical Fluids	Can be used with many common acids, alkalis, and solvents, excluding highly corrosive substances that may damage the seal materials.
Installation and Maintenance
Installation Method	Axial Installation	Installed axially onto the pump shaft following a strict installation procedure to ensure accurate alignment and reliable sealing.
Installation Torque	18 - 22 N·m	Apply a torque within this range during installation to firmly secure the seal without causing damage due to over-tightening.
Maintenance Cycle	Every 4000 operating hours	Regular maintenance is recommended every 4000 operating hours, including inspection for signs of wear, leakage, and proper alignment.
Storage Conditions	Store in a dry, cool environment with a temperature range of 5ºC - 25ºC. Keep away from direct sunlight and sources of radiation.	Proper storage conditions help maintain the integrity of the seal components and prevent premature deterioration.
Quality and Certification
Service Life	Approximately 2 - 3 years under normal operating conditions	With proper operation and maintenance, the QT-EVMS seal can provide reliable service for 2 - 3 years.
Leakage Rate	≤0.15 mL/h	Engineered to have a low leakage rate, ensuring the containment of pumped media within the system.
Certification Standards	ISO 9001, ISO 14001	Complies with ISO 9001 quality management system standards and ISO 14001 environmental management system standards, guaranteeing high-quality production and environmental sustainability.
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 its sealing performance even in environments with significant vibrations.
Self-lubricating Property	The seal surfaces are treated with a special coating to enhance self-lubricating capabilities, reducing friction and wear.	This self-lubricating feature helps to extend the service life of the seal and improve overall operational efficiency.

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.
