• Compact Cartridge: Engineered to fit into the limited space of a monoblock pump, bringing compressor-level gas seal technology to standard pumps.
• Safety Barrier: Ensures absolute containment of process vapors, making it ideal for API 682 Category 2 or 3 services.
Key Features
• Zero Emissions: An advanced non-contacting gas seal designed for monoblock pumps handling hazardous or environmentally sensitive fluids.
• Gas Lift Technology: Uses spiral grooves on the seal face to create a cushion of inert gas (Nitrogen), separating the faces and preventing contact.
• Low Power & Wear: Because the faces don't touch, friction and power consumption are negligible, and the seal faces do not wear out.

Workshop
This workshop is equipped with professional processing equipment and integrated with standardized material warehousing management, enabling a one-stop production process from precision machining to finished product delivery. It ensures part machining accuracy and production efficiency, meeting various high-specification manufacturing requirements.
Product Research, Development and Testing
Our Product R&D and Testing focuses on optimizing seal performance through advanced simulation and material analysis. All seals undergo rigorous trials, including thermal cycling and pressure tests, to ensure durability, minimal leakage, and long service life in demanding industrial environments.
Industry Solutions
Case Study
Solvent Tank Farm: Transfer pumps for Benzene required zero leakage. Liquid barrier systems were too complex. We installed this Dry Gas Seal with a Nitrogen panel. Zero emissions were achieved with minimal maintenance.
Testimonials
We switched our toxic service pumps to gas seals. The reliability is incredible compared to wet seals.

FAQs about Metal Bellows Seals for High Temperature Pumps
Q: Do I need a gas supply panel?
A: Yes, dry gas seals require a clean, regulated supply of barrier gas (usually Nitrogen) at a pressure higher than the pump product pressure (Plan 74).
Our company is specialized in the production of sealing materials, mechanical seals , cartridge seals.
