Tungsten Carbide
|
Tungsten carbide offers exceptional hardness and wear resistance, making it ideal for withstanding high - speed rotation and heavy loads in pump operations.
|
|
- Stationary Ring
|
Carbon Graphite
|
Carbon graphite provides good self - lubrication properties and excellent chemical resistance, contributing to smooth sealing and extended service life.
|
|
- O - Ring
|
Fluoroelastomer (FKM)
|
The FKM O - ring ensures a tight and reliable seal, with the ability to resist a wide range of chemicals and operate effectively across different temperature conditions.
|
|
Size Specifications
|
|
|
|
Shaft Diameter Range
|
25 - 60 mm
|
This seal can be installed on pump shafts with diameters within this range, offering flexibility for various pump sizes and configurations.
|
|
Seal Chamber Inner Diameter
|
35 - 70 mm
|
Designed to fit snugly into seal chambers with inner diameters in this range, ensuring proper alignment and optimal sealing performance.
|
|
Seal Width
|
9 mm
|
The 9 - mm width of the seal is carefully calibrated to balance sealing effectiveness and mechanical strength, reducing the risk of failure under pressure.
|
|
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 and maintaining system integrity.
|
|
Working Temperature
|
-25ºC - 180ºC
|
Capable of operating efficiently within this wide temperature range, the seal is suitable for applications that involve both extremely cold and high - temperature fluids.
|
|
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 pump operations.
|
|
Applicable Media
|
|
|
|
- Water - based Fluids
|
Suitable for clean water, cooling water, and various water - based solutions with a pH range of 2 - 13, including mildly acidic and alkaline liquids.
|
|
|
- Oil - based Fluids
|
Compatible with lubricating oils, hydraulic oils, and some synthetic oils, providing reliable sealing for oil - pumped systems.
|
|
|
- Chemical Fluids
|
Can be used with certain non - aggressive chemicals, such as solvents and some organic compounds, depending on the specific chemical properties and concentration.
|
|
|
Installation and Maintenance
|
|
|
|
Installation Method
|
Axial Installation
|
Installed axially onto the pump shaft following a precise installation procedure. Proper alignment and positioning are crucial for achieving optimal sealing performance.
|
|
Installation Torque
|
18 - 23 N·m
|
During installation, a torque within this range should be applied to ensure the seal is securely fastened without causing damage to the components.
|
|
Maintenance Cycle
|
Every 4000 operating hours
|
Regular maintenance is recommended every 4000 operating hours. This includes visual inspection for signs of wear, leakage, and proper functioning of the seal components.
|
|
Storage Conditions
|
Store in a dry, dust - free environment at a temperature between 5ºC - 25ºC. Avoid exposure to direct sunlight and strong electromagnetic fields.
|
Proper storage conditions help preserve the quality and performance of the seal, preventing premature aging and degradation.
|
|
Quality and Certification
|
|
|
|
Service Life
|
Approximately 2 - 4 years under normal operating conditions
|
With proper operation and maintenance, the Grundfo Pump B mechanical seal can provide reliable service for 2 - 4 years, reducing the frequency of replacement and maintenance costs.
|
|
Leakage Rate
|
≤0.05 mL/h
|
Engineered to have an extremely low leakage rate, the seal meets strict industry standards for containment of pumped fluids, ensuring safety and environmental compliance.
|
|
Certification Standards
|
ISO 9001, ISO 14001, and relevant industry - specific certifications
|
The seal complies with international quality management (ISO 9001) and environmental management (ISO 14001) standards, as well as other certifications required for specific industrial applications.
|
|
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 integrity in environments with moderate to high levels of vibration, 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 extends the service life of the seal and improves its overall efficiency, minimizing the need for additional lubrication.
