pcs.

 

NV-1D universal double seal for water and chemical pumps

 

Analog:

Burgmann M74-D

 

Design with a set of small springs.

Not hydraulically unloaded.

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

Dimensions to DIN 24960 (EN12756).

Materials of friction pair:

- carbon-impregnated carbon resin (B)

- antimony impregnated carbon graphite (A)

- silicon carbide (Q1, Q2)

- tungsten carbide (U3)

- ceramic Al O (V) 2 3

 

Elastomers:

- fluorine rubber, FKM (V)

- nitrile rubber (P)

- ethylene-propylene rubber, EPDM (E)

- PTFE

 

Parameters:

- p = 16 (25) bars

- t = -50 ... 220В°C

- v = 20 m/s

 

Do not require any adaptation 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)
