High - Performance HSPBT Series Mechanical Seals
Characteristics and Application Scenarios of Series - Type Bellows Seals
The HSPBT series is an advanced line of series-type bellows mechanical seals, ideal for the PLAN55 system. It allows a moderate amount of buffer fluid into the process medium, a key feature for stable operation.
With non-contact operation, these seals cut power consumption for efficiency and ensure long service life, lowering replacement and maintenance costs. They offer flexibility: both the medium-side main seal and atmosphere-side secondary seal can be liquid film seals, or the latter a contact-type. Requiring external buffer fluid for optimal performance, they excel at sealing pumps handling high-temperature and multiphase media, making them reliable for demanding industrial settings.

1. Product Advantages (Forever Seals HSPBT Series)
Superior Durability: Adopts high-grade bellows materials and precision machining, ensuring 30% longer service life than standard mechanical seals, reducing downtime for industrial equipment.
Energy Efficiency: Non-contact operation design minimizes friction, cutting power consumption by 15%—a key advantage for long-term cost savings.
Flexible Configuration: Supports dual options for seals (liquid film or contact-type for the atmosphere-side secondary seal), adapting to diverse working conditions without extra customization fees.
Stable Sealing Performance: Optimized for the PLAN55 system, it precisely controls buffer fluid infiltration, preventing medium leakage and ensuring compliance with industrial safety standards.
2. Working Principle
The HSPBT series operates on a dual-seal structure (medium-side main seal + atmosphere-side secondary seal). When in use, external buffer fluid (required for optimal performance) is introduced to form a stable barrier. The non-contact main seal reduces friction, while the secondary seal (configurable as liquid film or contact-type) provides a backup barrier. This design ensures that high-temperature or multiphase media in pumps are sealed tightly, avoiding leakage and maintaining process stability—consistent with Forever Seals’ commitment to reliable sealing solutions.
3. Product Details
Material Selection: Bellows made of corrosion-resistant alloy; seal faces use wear-resistant silicon carbide (SiC) or tungsten carbide, suitable for harsh media.
Structural Design: Compact series-type bellows layout, easy to install and disassemble, compatible with most standard pump models.
Performance Parameters: Operating temperature range: -20°C to 280°C; maximum pressure: 1.6MPa; suitable for media viscosity up to 1000cP.
Quality Assurance: Each unit undergoes 100% pressure testing and leakage detection before delivery, meeting ISO 9001 quality standards (Forever Seals’ quality guarantee).
4. Application Range
Ideal for sealing pumps in the following industries:
Petrochemical: Handling crude oil, gasoline, and other multiphase media.
Power Generation: Sealing high-temperature water or steam circulation pumps.
Chemical Processing: Suitable for corrosive or viscous chemical media (e.g., acids, alkalis).
Pharmaceutical & Food: Complies with sanitary standards for non-toxic, low-pollution sealing needs.
5. FAQ
Q1: Does the HSPBT series require special maintenance?
A1: No—its long service life and simple structure only need quarterly inspection of buffer fluid levels; Forever Seals provides a maintenance guide for free.
Q2: Can it replace other series seals in existing pumps?
A2: Yes, it has a universal installation size, compatible with most pump models; our technical team offers replacement guidance.
Q3: What after-sales support does Forever Seals provide?
A3: We offer a 12-month warranty, 24/7 technical consultation, and on-site maintenance service for bulk orders.
