Seal Chamber
Place unit on its side with oil fi ll plug downward, remove plug (a 3/8” drive socket extension works well)
and drain all oil from seal chamber, checking oil for contamination (milky white oil indicates the presence of
water.)
Perform Pressure Check
NOTE: This test is to be performed with NO oil in the housing.
CAUTION: Make certain the cord set is attached to pump. Performing the pressure check without the cord
set on may cause the terminal block to blow out.
To check the pump for any seal leaks, attach the pressure gauge assembly using pipe sealant. TIghten the
fi tting into the hole. Pressurize the gauge to 8 to 10 psi. Use a soap solution around the sealed areas and
inspect joints for air bubbles.
If, after 5 minutes the pressure is still holding constant, and no bubbles are observed, slowly bleed the
pressure and remove the gauge assembly. Replace the pipe plug using sealant. If the pressure does not
hold, then the leak must be located and repaired.
