1. Product Advantages
High Compliance and Reliability: Meeting API 682 and JB 8723 standards, the HSPBS - 1 ensures strict sealing performance to prevent leakage. It comes with single - end face and double - end face sealing options to cater to different sealing needs.
Wide Adaptability: It can handle pressures from 0 to 2.0 MPa (single - layer) and up to 6.9 MPa (double - layer). Suitable for linear speeds ≤25/50 m/s and temperatures ranging from - 75 to 425 °C, making it fit for various harsh working conditions.
Diverse Configurations: Offered in cartridge and non - cartridge styles, as well as a balanced - type design. It also comes in stationary (606 type, 604 type) and rotating (609 type) forms, providing flexibility for different installation and operational requirements.
2. Working Principle
The bellows component in the HSPBS - 1 acts as a flexible element, providing necessary axial compensation. When the equipment shaft rotates, the rotating part of the seal moves with the shaft, while the
part remains fixed. The close contact between the sealing faces, maintained by the bellows and auxiliary sealing elements, prevents the medium from leaking, thus achieving effective sealing.

5. FAQ
Q1: What is the difference between single - end face and double - end face sealing in HSPBS - 1?
A1: Single - end face sealing uses one pair of sealing faces, suitable for relatively clean media. Double - end face sealing has two pairs of sealing faces, providing better sealing for more demanding or hazardous media.
Q2: Can HSPBS - 1 be used in high - temperature applications?
A2: Yes, it can operate in temperatures up to 425 °C, making it suitable for high - temperature environments.
Q3: Are cartridge seals of HSPBS - 1 easier to install?
A3: Yes, cartridge seals come as a pre - assembled unit, simplifying installation and reducing the chance of installation errors.
