John Crane 502 Water Pump Mechanical Seal 100mm For Industrial Pumps
Mechanical Seal John Crane 502 Water Pump Seal Mechanical Seal
Our mechanical seal model 502 can replace AESSEAL B07S and CRANE
502 ,which is widely used for industrial pumps. BO seat and BP seat
are usually used for 502 type. The normal material combination
include resin carbon/ceramic/nbr/ss304,resin
carbon/tc/nbr/ss304,sic/sic/nbr/ss304 ,tc/tc/nbr/ss304 and so on.
we also can make changes as customers'requirement or totally design
a new type of mechanical seal to meet clients'needs.
BGM 502

Fixing and Applying Directions of Mechanical Seals
1. Select Appropriate mechanical seal to match the materials
according to work conditions and host machine equipment.
2. The radial acting deviation for the shaft(shaft sleeve) of
the installed mechanical seal shall be 0.04mm by maximum
while the axial movement value of the rotor shall be no more than
0.1mm.
3. The seal cover (or shaft cover) of the stationary ring of
the installed mechanical seals,the vertical degree of the seal
face should be 0.04mm by maximum.
4. When installing the mechanical seals,the shaft(shaft
sleeve),seal chamber,seal face as well as the mechanical seal
must be cleaned in order to keep from any medium to sealing part.
5. When conveying medium of over high or low temperature,with
medium which are easy catch fire,easy for explosion.
Related mechanical seal standards must be referred to take
appropriate measures such as quench,rinsing,coolong and
filtrating.
6. Appropricate lubrication must be choosen when mechanical
seal is installed.The installment size of the mechanical
seal must be guaranteed to the installment instruction.
7. Before the machine starts running,the hermetic compartment
shall be full of medium and well lubricated.Dry friction
which may lead to the damage of the air-tightness is strict
forbidden.
