Valve Lubrication
1.
On handwheel-type valves, including PM, PMD, and Transfer Valve Con-
trols, if necessary, first remove old grease and paint, use a dry lubricating
spray on gears.
2.
Lubricate suction threads with a light coat of grease.
Check Gearbox or Pedestal Lubrication
❑
To check the gearbox, see heading “Gearbox Option” on page 56.
❑
To check the pedestal reservoir, see heading “Pedestal Option” on page 57.
Pump and Flange Bolts
Check all pump and flange (bell housing) bolts to ensure:
❑
No bolts are missing.
❑
All bolts are tight. Use a torque wrench and torque bolts to the manufac-
turer's recommended specifications.
❑
Bolts used are “Grade 5” strength minimum for mounting and “Grade 8”
strength minimum for the driveline.
Priming System Test (Dry Vacuum Test)
(Refer to NFPA 1901 or NFPA 1911)
1.
Close all valves and drains. Cap all suction open-
ings and the outlet of the suction side relief valve (if
equipped).
2.
Connect a test vacuum gauge or manometer to the
intake test gauge connection on the pump panel.
3.
Engage the priming pump until the gauge indicates
at least 22” Hg vacuum. (See Figure 4-3: “PVG
Priming Valve Handle.”)
4.
Compare the readings of the test gauge and the apparatus gauge. Note
any difference.
