Provides a reliable seal and is highly resistant to water, steam, and a wide range of polar substances, ensuring durability in diverse media environments.
|
|
Size Specifications
|
|
|
|
Shaft Diameter Range
|
25 - 60 mm
|
Compatible with pump shafts within this diameter range, making it suitable for multiple Hidrostal pump models.
|
|
Seal Chamber Inner Diameter
|
35 - 70 mm
|
Specifically engineered 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 width is carefully calibrated to balance sealing effectiveness and minimize frictional losses, enhancing the overall efficiency of the pump system.
|
|
Performance Parameters
|
|
|
|
Working Pressure
|
Maximum 2.0 MPa
|
Under normal operating conditions, the seal can effectively withstand a maximum pressure of 2.0 MPa, preventing leakage of the pumped medium.
|
|
Working Temperature
|
-30ºC - 180ºC
|
Capable of operating efficiently within this wide temperature range, making it suitable for both extremely cold and high - temperature industrial applications.
|
|
Linear Velocity
|
Maximum 12 m/s
|
Designed to maintain stable sealing performance even at high linear velocities of up to 12 m/s, ensuring reliable operation in high - speed pump systems.
|
|
Applicable Media
|
|
|
|
- Water - based Fluids
|
Ideal for clean water, raw water, sewage, and water - based chemical solutions with a pH range of 2 - 13.
|
|
|
- Oil - based Fluids
|
Suitable for lubricating oils, gear oils, and some non - aggressive hydrocarbon - based oils.
|
|
|
- Other Fluids
|
Can handle certain food - grade fluids, making it applicable in the food and beverage industry when properly certified.
|
|
|
Installation and Maintenance
|
|
|
|
Installation Method
|
Axial Installation with Centering Guide
|
Installed axially onto the pump shaft using a centering guide to ensure precise alignment, which is crucial for optimal sealing performance.
|
|
Installation Torque
|
18 - 22 N·m
|
During installation, a torque within this range should be applied to securely fasten the seal without causing damage to its components.
|
|
Maintenance Cycle
|
Every 4000 operating hours
|
Regular maintenance every 4000 operating hours is recommended. This includes visual inspection for wear, leakage, and proper alignment, as well as cleaning and, if necessary, replacement of worn parts.
|
|
Storage Conditions
|
Store in a dry, dust - free environment at a temperature between 5ºC - 25ºC. Avoid exposure to direct sunlight and ozone - containing gases.
|
Proper storage conditions help preserve the integrity of the seal materials and extend its shelf life.
|
|
Quality and Certification
|
|
|
|
Service Life
|
Approximately 2 - 4 years under normal operating conditions
|
With proper operation and maintenance, the Queeny-Hidrostal Pump 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 maintaining the safety and efficiency of the pump system.
|
|
Certification Standards
|
ISO 9001, ISO 1400
|
Meets international quality management (ISO 9001) and environmental management (ISO 14001) standards. Food - grade, ensuring compliance with food safety regulations.
|
|
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 even in environments with significant vibrations, which is common in many industrial pump installations.
|
|
Self - aligning Feature
|
Incorporates a self - aligning mechanism that compensates for minor shaft misalignments, reducing stress on the seal and improving its overall performance and lifespan.
