BV-3 Balanced mechanical seals

bv-3 гидравлически разгруженное торцевое уплотнение с набором пружин
(0)
$0.00
pcs.

 

BV-3 hydraulically balanced mechanical seal with spring kit

 

Analog:

Burgmann HRN

 

Design with a set of small springs.

Springs are not in contact with the pumped liquid.

Ideal for viscous fluids, abrasive fluids, etc.

Fixed spring assembly.

Hydraulically unloaded.

It does not depend on the direction of rotation of the shaft.

Dimensions to DIN 24960 (EN12756).

 

Materials of friction pair:

- carbon graphite (A, B)

- tungsten carbide (U3)

- silicon carbide (Q1, Q2)

- ceramic Al O (V) 2 3

 

Elastomers:

- fluorine rubber, FKM (V)

- nitrile rubber (P)

- ethylene-propylene rubber, EPDM (E)

- perfluorinated rubber, FFKM (e.g. KalrezВ®)

- fluoropolymer in fluoroplastic sheath, FEP

 

Parameters:

- p = 25 bars

- t = -50 ... 220В°C

- v = 20 m/s

 

Does not require modification of the pump.

 

When ordering the seal, it is necessary to specify the pump brand, shaft diameter, working conditions (pumped working medium, temperature) and the type of fixed connection (seats, rings)
