HM11C

详细说明

Design Features:

n A mechanical seal is in tandem with a dry gas seal, the mechanical seal is the primary seal and the dry gas seal is backup seal;

n The dry gas seal operates no-contacting so that the primary seal has a certain back pressure, which can effectively prevent the primary seal unstable operation caused by the liquid-film gasification (or vaporization) between the primary seal faces. So the life of the primary seal can be extended greatly;

n Primary leakage can be flared with buffer gas, so the process gas cannot leak out to atmosphere;

n When the primary seal failures, the gas seal can be acted as primary seal;

n Cartridge structure，easy to install and precisely positioning.

Performance Capability:

n Temperature: -60~200℃;

n Pressure: ≤6MPa;

n Speed: 500~3000rpm;

n Application: for use in volatile fluid, e.g., light hydrocarbon.
