Stainless Max Series Pumps
Gearbox Lubrication
Too much oil or the wrong type of oil will result in unnecessary loss
of power and high oil temperature. Change the oil every 12 months,
depending on pump usage. Refer to Table 4-2: “Recommended
Lubricants” for Hale recommended oils and gearbox capacities.
1. Remove the gearbox oil fill plug, and check the level of the oil in
the gearbox. See Figure 4-3: “Sample Fill Plug.”
The oil level should be up to the plug hole.
2. If the oil appears white or “milky,”
a water leak is indicated. Re-
move the drain plug and drain
the oil into a suitable container.
Examine the oil for metal flakes or other contamination. Either of
these conditions indicates maintenance is required on the unit.
Priming System Test (Dry Vacuum Test)
(Refer to NFPA 1901 or NFPA 1911)
1. Close all valves and drains. Cap all
suction openings and the outlet of the
suction side relief valve (if equipped).
2. Connect a test vacuum gauge or manom-
eter to the intake test gauge connection
on the pump panel.
3. Engage the priming pump until the gauge
indicates at least 22 IN-hg vacuum. See
Figure 4-4: “Prime Control.”
