Why is my mechanical seal continuously failing?
Why is my mechanical seal continuously failing?
(OP)
Hey guys,
I'm Running white latex paint for abrasive wear test.
Mechanical seals are failing early, and at low pressure.
Why?
<50psi
silicon carbide is the stationary seat.
hardened steel is the rotating face.
I've only been able to find one ref. online saying latex balls up between seal faces. can anyone point me to a good ref.?

The other solution is to go for a knife edged seal. These are usually formed metal bellows seals with tungsten faces one of which is extremely narrow. The principle is not to allow the formation of a fluid film and use very wear resistant faces. The heat generated by high, effectively dry, contact pressure is dissipated by a low pressure water quench on the atmospheric side of the seal (usually less than 0,3 Bar) at a flow rate of around 1/L.Min. You should normally get up to 2 years life with this approach.
If you would like more info please em me.
