To check the lubrication oil level of the mechanical seal perform the following:

Checking Lubrication Oil Level

1.Lay the pump (Figure 17) on its side with the oil plug facing upwards.

2.Remove oil ﬁ ll plug.

3.Visually inspect oil plug hole to verify that oil chamber is full enough to cover seal spring.

4.When reinstalling oil ﬁ ll plug, apply teﬂ on tape to prevent leaking.

WARNING

When removing oil ﬁ ll plug, please note that pressure may have built up in the oil chamber. DO NOT fully remove plug until pressure has been relieved.Turn oil ﬁll plug slowly to relieve pressure.

Changing Lubrication Oil

1.If lubrication oil level is low, block the oil ﬁ ll opening with a ﬁ nger and roll pump to one side to drain oil into a small container.

2.Use a funnel (Figure 17) and ﬁ ll oil chamber with ISO VG32 lubrication oil or equivalent. Oil chamber capacity is 74.4 oz. (2.2 liters). Fill to 75-80% capacity to allow for expansion. Replace lubrication oil once a year or 3,000 hours.
