Lubrication

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

Checking Lubrication Oil Level

1.Lay the pump (Figure 16) on its side with the oil plug facing upwards.

2.Remove oil fill plug.

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

4.When reinstalling oil fill plug, apply teflon tape to prevent leaking.

WARNING

When removing oil fill 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 fill opening with a finger and roll pump to one side to drain oil into a small container.

Use a funnel (Figure 16) and fill oil chamber with ISO VG32 lubrication oil or equivalent. Oil chamber capacity is 40 oz. (1,200 cc) for ST41230/ST41460 and 47 oz (1,400 cc) ST61230/ST61460. Fill to 75-80% capacity to allow for expansion. Replace lubrication oil once a year or 3,000 hours.
