Legend for seal selection by media (starting page 3)

̈ Preferred materials

1)Standard following EN 12756, Dec. 20002)Shortway acc. to ISO 1629, Nov. 2004

Notes on the medium (2)

G = Mixture/group N = Natural product ®= Trade mark S = Collective term V

= Impurities

Concentration (3)

–= “any“

< 10= less than 10 weigth %ϳ10= approx. 10%F10= Solids up to 10%L = Defined solution < L = Unsaturated solution > L = Supersaturated sol.Sch = Melt

Sus

= Suspension

Temperature (4)

< 100= less than 100 °C > F = > Solidifying temp.> K = > Crystallization

temperature

< Kp =< Boiling temperature > Pp => Pour point TG =< Material tempera-ture limit

Arrangem.of shaft seal (5)

S = Single mechanical seal S1= Internal arrangement S2= External arrangement S3

= Internal arrangement with rotating counter ring

D = Dual mechanical seal D1= Back-to-back D2= Tandem

D3= Face-to-face

Q = Quench

Q1= Without throttle bushing

Q2= With throttle bushing

Q3

= With auxiliary seal

Auxiliary piping (6)

00= None (“dead end“)01= Internal circulation 02= Connection from pump case 08= Supply of external fluid 08a = Flushing 08b = Quench (static)09= Throughflowing

quench or buffer fluid 10= Circulating quench

or buffer fluid,

pressureless

11= Same as 10, but

pressurized 12= Pressure transmitter

Auxiliary measures (7)

D = Steam quench

(H), H = Heating (if necessary)

kD = Conical stuffing box

SS = Splash guard

SW = Replacement of

buffer medium

QW = Replacement of

quench medium

ThE = Thermal buffer

Mechanical seal type on product side (8)1= With elastomer O-rings, rotating springs in contact with the product 2= same as 1 but springs not in contact with the product 3= same as 2 but

stationary springs 4= same as 2 but metal-free on product side

5= with elastomer bellows 6= with metal bellows X = special design Material selection (9)For designations acc. to EN 12756see table of materials.Health hazard warnings (10)A = Corrosive C = Carcinogenic C1= Proven in humans C2= Proven in animal experiments C3= Suspected for good reason G = Toxic H = Skin resorption R = Irritant S = Sensitization X = Moderately toxic 1= Vapour pressure/gas

2

= Corrosion 3= Exclusion of air 4= Lubricating properties 5= Icing risk 6= Leakage

7= Readily flammable 8= Flame-promoting 9= Potentially explosive 0

= Insufficient information

TLV (11)

a fig.= TLV in ppm mg = TLV in mg/m 3

#= mg/m 3of base substance *
