Mechanical seals

MBC4

Description:

- Single seal
- Balanced
- With spring set
- Rotation direction independent

Applications:

MBC4 construction is specially designed for pump chambers working at high pressure. A variety of seal faces and seats can be used. For liquids with particles seal set should be made of tungsten carbide (TC) or silicone carbide (SiC). MBC4 is used in pumps transporting neutral and aggressive liquids containing or not mechanical particles.

Parts and materials:

1 Elastomer: EPDM, FPM (VITON), NBR, PTFE

2. Seat:
A - Graphite antimony impregnated
B - Graphite resins impregnated,
G - Stainless steel DIN 1.4571,
T - Inconel DIN 2.4856,
V - Aluminum oxide (Al2O3),
Q - Silicone carbide (SiC),
