IMPORTANT NOTE
The importance of seal chamber priming cannot be overemphasized. Due to the prevalence of
seal damage and leakage caused by not filling the seal chamber with liquid before putting a
pump in service, this page is located at the beginning of this document.
SEAL CHAMBER PRIMING
Fill mechanical seal chamber with liquid to insure seal does not start dry. This can be done by
removing seal vent set-screw and pouring liquid into vent passageway before opening pump
inlet. Alternately, seal chamber can be vented in situations where inlet pressure is above
atmospheric by opening inlet and discharge valves and then loosening seal vent plug to allow
positive inlet pressure to push air out of seal chamber until oil flows from it.
See
figure below.
Filling or Venting Seal Cavity Using Seal Vent
CAUTION
Failure to fill or vent seal chamber as described above may cause damage to seal running
faces which may result in seal leakage.
