DOUBLE MECHANICAL SEALS FOR MIXERS

(0)

2tmp2ТМР – are double mechanical seals intended for sealing of mixer shafts, chemical reactors and other equipment, that don’t permit pumped liquid leakages

2ТМР-П – is the version with an rolling bearing

2ТМФ – are multi spring balanced double mechanical seals of cartridge type, fluoroplastic secondary seals are located on atmosphere side

2ТМФ-П – is the version with an rolling bearing

DESIGN FEATURES

– friction pairs hydraulically balanced
– cartridge design (ease at mounting/dismounting)
– springs are located in barrier fluid
– secondary seal: non-metallic throttle bush
– barrier fluid is supplied into the mechanical seal from the external source
– mechanical seals may be used in conjunction with reservoir, and barrier fluid circulates from mechanical seal into the reservoir. In this case the pressure of barrier fluid exceeds the pressure in the mechanical seal chamber

MATERIALS USED

-seal housing parts are from steel of grade 304, 304L, 316, 316L, titanium
– friction pair seal rings are from silicone carbide, tungsten carbide
– o-ring are rubber rings made from FKM, FFKM, EPDM, rubber rings fluoropolymer sheathed rubber rings

MAIN CHARACTERISTICS OF MECHANICAL SEALS

sealing pressure to 30 atm
temperature of sealed fluid/gas: from minus 30 to 200 0С*

* When the thermal barrier is used in the chemical device, temperature shall be up to 4000С
