HZDT Sealing:Braided Packing-Aramid Fiber Packing

GH-220 Aramid Filament with PTFE Packing (NA)

Construction: GH-220 is an interlock braided packing using aramid yarn treated with PTFE suspensoid. The packing is also lubricated with a silicon-based compound for quick and easy break-in.

Application: It is an extremely durable packing able to withstand granular and abrasive applications. It is recommended for service in superheated steam, slurries, petroleum derivatives, solvents and liquified gases. It is commonly used in centrifugal, rotary and reciprocating pumps, agitators and mixers, especially in the paper, steel, petroleum and chemical industries, and in sewage treatment plants.

Service Limits:


Pressure (Bar)	50	300	500
Temperature (°C)	-100~280
Shaft Speed (m/s)	0~15
PH Range	2~12

GH-221 Spun Aramid with PTFE Packing (NA)

Construction: GH-221 is an interlock braid, using Spun aramid carded yarns, treated individually with PTFE suspensoid. The packing is also lubricated with silicone based compound for quick and easy break-in. The use of spun aramid fibers produces a softer and very tough packing, but one that is less abrasive than packings braided with aramid filaments.

Applications: It is a durable packing able to withstand granular and abrasive applications. It is recommended for service in superheated steam, slurries, petroleum derivatives, solvents, chemicals, liquified gases, pulp and paper stocks, sugar syrups, and other abrasive fluids.

Service Limits:


Pressure (Bar)	30	200	400
Temperature (°C)	-100~280
Shaft Speed (m/s)	0~15
PH Range	2~12

GH-230A-1 PTFE packing with Aramid corners (NA)

Construction: This is an interlock braided packing, using pure PTFE yarn, reinforced with aramid corners. The yarns are pretreated with PTFE dispersion, plus a break-in lubricant to reduce the coefficient of friction, as well as the frictional heat created by high shaft speeds.

Application: with its unique combination of PTFE and aramid fibers, is dimensionally stable, non-contaminating, has excellent lubricanting and running characteristics, and because of the aramid corners, is very wear resistant. It handles acids, alkalies, and a broad range of chemicals. It is well suited for service in rotary and reciprocating pumps, mixers, agitators and reactors, especially where abrasive wear is a problem.

Service Limits:


Pressure (Bar)	30	200	300
Temperature (°C)	-100~280
Shaft Speed (m/s)	0~15
PH Range	1~13

GH-230A-2 PTFE/Graphite packing with Aramid corners (NA)

Construction: This packing is an interlock braid of PTFE/graphite yarn, reinforced with high strength aramid yarn corners匛G2 yarn is formed from expanded PTFE in which fine particles of graphite have been encapsulated匱he resulting packing provides good chemical resistance and heat dissipation plus anti-extrusion strength.
Application: The packing can handle a broad range of chemicals in the 3-11 pH range. It is used in paper mill stock pumps, agitators, or any service where high strength and good lubricating qualities are needed.

Service Limits:


Pressure (Bar)	30	200	300
Temperature (°C)	-100~280
Shaft Speed (m/s)	0~20
PH Range	1~13
