General Information |
|
Model Number |
QT - CDPN |
Application |
Suitable for various industrial pumps, compressors, and rotating equipment in chemical, petrochemical, and water treatment industries. |
Design Type |
Single - spring, balanced mechanical seal |
Dimensions |
|
Bore Size (mm) |
20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100 |
Outer Diameter (mm) |
Based on bore size, with an additional range of 10 - 30 mm depending on the specific model. For example, when bore size is 20mm, outer diameter is 40mm; when bore size is 50mm, outer diameter is 75mm. |
Width (mm) |
15 - 25, varies according to the bore size. Smaller bore sizes usually have a width of around 15mm, while larger bore sizes can reach up to 25mm. |
Performance Parameters |
|
Pressure Rating (MPa) |
0 - 4.0. It can withstand a maximum pressure of 4.0 MPa under normal operating conditions. |
Temperature Range (°C) |
- 20 to 180. The mechanical seal can operate effectively within this temperature range. |
Shaft Speed (rpm) |
Up to 3000. It can adapt to shaft speeds of up to 3000 revolutions per minute. |
Leakage Rate (ml/h) |
Less than 5. Under standard test conditions, the leakage rate is controlled to be less than 5 milliliters per hour. |
Material Properties |
|
Seal Face Material |
Carbon - silicon carbide combination. The carbon seal face has good self - lubricating properties, while the silicon carbide seal face has high hardness and wear resistance. |
Secondary Seal Material |
A high - performance elastomer. It has good chemical resistance and elasticity, ensuring a reliable seal. |
Spring Material |
Stainless steel. It provides stable elastic force and corrosion resistance. |
Installation Requirements |
|
Installation Torque (N·m) |
For different bore sizes, the installation torque varies. For bore sizes of 20 - 30mm, the installation torque is 5 - 10 N·m; for bore sizes of 31 - 50mm, it is 10 - 15 N·m; for bore sizes larger than 50mm, it is 15 - 25 N·m. |
Shaft Surface Roughness (μm) |
Ra 0.2 - 0.8. The shaft surface roughness should be within this range to ensure a good sealing effect. |
Housing Bore Surface Roughness (μm) |
Ra 0.4 - 1.6. The housing bore surface roughness needs to meet this requirement for proper installation and sealing. |
Quality Assurance |
|
Testing Standard |
Comply with ISO 21049 standards. All products are tested to ensure they meet the specified performance and quality requirements. |
Service Life (Hours) |
More than 8000. Under normal operating conditions, the mechanical seal can provide a service life of more than 8000 hours. |
Warranty Period |
12 months from the date of installation. During the warranty period, free repair or replacement will be provided for quality - related issues. |
