Specifications
- Compact
The single cartridge seal is especially designed for use in the standardised installation spaces of the non-API pump MCPK (CPKN + CPK possible). - Flexible
The mechanical seal can be connected to all common API Plans, such as 01, 02, 11, 31, 32 + 61 (62) and 23 + 61 (62). - Dependable
Floating throttling bush for optional connection of a gas or steam quench. This prevents outboard incrustations at the seal. - Robust
The mechanical seal is available in a hard-soft combination of silicon carbide and carbon graphite, or in a hard-hard combination of silicon carbide and silicon carbide. - Materials
The seal contains O-rings as secondary sealing elements. They are available in different material variants
The space between the two mechanical seals is flushed with a buffer or barrier fluid, depending on the application. This completely absorbs any leakage of the fluid pumped. In addition, the heat is transported away from this area. The double pressure balanced mechanical seal can be operated with pressurised barrier fluid or unpressurised buffer fluid.
