Design Features
 Dual-face, corrugated pipe, the structure of balance
 Primary seal on side of the medium and secondary on side of the atmosphere are oil film sealing, non-contact operation, low power consumption, long service life.
 The relatively high pressure and the low temperature cooling oil enter between primary and secondary seal, not mix with the sealed media, and cooling oil low consumption.
 Seal face use the outer diameter slot face sealing structure that have the right of independent intellectual property, which has excellent dynamic stability under high temperature.
 Primary seal fail, vice seal can be up safety seal function, prevent high temperature oil leaking to air.
 Assisting sealing use the flexible graphite bedding, resistance to high temperature and low cost.
 Container type structure and the overall installation accurate, convenient, knocked-down work are convenient.
Operation Parameters
 Pressure from 0 MPa to 3.0 MPa
 Line-speed: not more than 25 m/s
 Temperature from 100℃to 425℃
System Configuration
 API 682 Plan 54 + 61
Application Condition
 Refinery often relief devices, catalytic unit, reforming unit, hydrogenation, cracking unit, asphalt devices, etc.
 Various centrifugal pump of screw pump, etc.
Conveying high temperature of oil pump high temperature, such as the bottom and pump, wax oil pump, oil pump, restructuring slag asphalt pump etc.
