4.6 ANNUALLY
❑ Replace the pump gearbox oil. (See Figure 4-2: “Gearbox Capacity /
Recommended Lubricants,” on page 45.)
❑ Check individual drain lines from the pump to the multi-drain to ensure
proper drainage and protection from freezing temperatures.
❑ Test tank-to-pump flow rate. (See page 49.)
❑ Clean ESP Primer, if installed. (See separate manual provided.)
❑ Perform the yearly pump test to check performance levels. (See NFPA
Standard 1911 for more details.)
Replace Gearbox Oil
1. Remove the drain plug (magnetic) and drain the gearbox oil into a suitable
container. (See Figure 4-3: “Typical Drain, Fill and Level Plugs,” on page 46.)
Note: Assembly orientation determines which plugs are used for oil fill, drain and
level detection. See installation plate drawings located at the back of this manual.
2. Examine the oil for contamination (e.g., water – turns the oil a milky color or
settles to the bottom). Properly dispose of the used oil.
3. Inspect the magnetic drain plug. If metal filings are present on the drain plug,
remove the cover plate to visually inspect and clean the internal components.
Repair or replace components as necessary. See Section 6 “Repair” on page
61
4. Replace the cooler or cover, if necessary. Remove the oil fill plug and the
level detect plug. Clean the drain plug (magnetic).
5. Fill the gearbox with an approved gear oil until oil just begins seeping from the
level plug opening. See Figure 4-3: “Typical Drain, Fill and Level Plugs” on
page 46 for fluid types and quantities.)
6. Install all plugs.
Check Drain Lines to Multi-Drain
Drains are supplied on the pump and piping at the lowest points where
water could collect and freeze, rendering the pump ineffective.
