Leakage - Twin Screw Pump

Leakage - Twin Screw Pump

Leakage - Twin Screw Pump

(OP)
Dear all,

I install RUSCH twin screw pump, duty is Palm Oil Transfer Pumps, fitted with Mechanical Seal. The pump have product (palm oil) leakage on bearing housing, which I suspect cause by Mechanical Seal failure. However, the leakage stop if I run the pumps.

Should I check the Mechanical Seal? I think Mechanical Seal failure will lead to leakage when the pump run.

Advise, please.  

RE: Leakage - Twin Screw Pump

It is possible that the seal can be leaking statically but not dynamically.  Depending on the seal design, the pressure balance on the faces can vary depending on the conditions the seal sees.  We've had problems with very high pressure seals leaking slightly under static conditions due to the requisite stiffness of the faces for sealing the dynamic pressures.

However, if the leakage is not a regular occurrence, you may need to have the seal changed.
