our Mechanical seal model 109B is widely used for industrial pumps. The normal material combination include resin carbon/ceramic/PTFE/ss304,resin carbon/tc/PTFE/ss304,sic/sic/PTFE/ss304 ,tc/tc/PTFE/ss304 and so on. we also can make changes as customers'requirement or totally design a new type of mechanical seal to meet clients'needs.
TS 109B
Operating Limits:
Pressure: ≤2.5MPa
Speed: ≤25m/s
Temperature: -30ºC~+200ºC
Stationary Seats:
1. The standard seat for the TS 109 is the type "A" seat.
2. Type P and PP seats are also available.
Rotary Ring (Carbon/SiC/TC)
Stationary Ring (99%Ceramic/SiC/TC)
Secondary Seal (PTFE)
Spring & Other Parts (SUS304/SUS316)
Structural Features:
1. Uses a PTFE secondary seal for corrosion resistance in applications for the chemical industry.
2. Applications include all types of rotating equipment, such as centrifugal pumps, mixers, and agitation crushers.
3. Mechanically driven, reducing attrition from the shaft and sleeve. Seal runs in two directions.
4. Seal is a multi-spring, unbalanced type that meets API610 standards.
