Design Features
 Dual-face, multiple-spring, balance type, structure of pressure on sealing outside diameter.
 Primary seal on the side of the medium and secondary on the side of the atmosphere are double balance, counter-attack pressure design.
 Primary and secondary sealing are gas film sealing, non-contact operation, low power consumption, long service life.
 Between primary and secondary sealing access to clean nitrogen or instrument winds as jam gas, guarantees that process medium from pollution
 Structure of auxiliary system is simple.
 Realize sealed media zero leakage, zero emission, free from pollution to the environment.
 Container type structure, and the overall installation accurate, convenient, knocked-down work is convenient.
Operation Parameters
 Pressure from 0 MPa to 2.5 MPa
 Line-speed: not more than 25 m/s
 Temperature from - 40℃ to 327℃
System Configuration
 API 682 Plan 74which applies to allow a few jam gases into the media side.
Application Condition
 Butadiene device, food processing device, aromatic device, methanol device, acrylonitrile device, chloride methane devices, etc.
 All kinds of normal centrifugal pump, high-speed pump, submerged pump, etc.
 Clean ammonia, amine water, heat-conduction oil, solvents, pure benzene, toluene, xylene, liquid chlorine, methanol, tar, etc.
