Long Term Storage
Long-term storage is defined as any period when the pump is in storage or idle in
excess of six (6) months. If the pump has been in service, drain any fluid from the
pump fluid end, flush the fluid end with water to clean out any of the remaining
pumpage, and blow dry using compressed air. Pour internal rust inhibitor oil described
in Table 3: Lubricant Recommendations, into the suction and discharge ports of fluid
end, and then install pipe plugs in openings. Use the same quantity as described in 3.2.
Drain the oil from the pump power end. Remove the rear cover to expose the drive
components. Spray all internal parts with a rust preservative that is soluble in
lubricating oil while rotating the driveshaft several turns by hand to ensure complete
coverage. Replace the rear cover and add 1 to 1-1/2 cups of internal rust inhibitor with
those or equivalent recommended in Table 3.
Spray a rust preventative onto all exterior machined surfaces paying attention to any
unpainted areas like the crankshaft extension. Remove the oil fill cap and cover the
breather opening with a plug or other suitable means in order to keep the preservative
atmosphere sealed inside the power end.
Never store the pump on the floor or ground. Always place it on a shelf or pallet that is
several inches above ground level. Cover the entire pump with a canvas or plastic tarp.
Every two months inspect the unit. Rotate the crankshaft by hand at least 4 turns
during each inspection. Drain and replace the rust inhibitor after every six (6) months of
storage.

Returning a Stored Pump to Operation
Before operating a pump that has been prepared for storage, drain the preservative and
lubricating oil mixture from the power end (crankcase). Reinstall the drain plug,
breather/filler cap, and any other components that were removed for storage. Once
these steps have been completed, follow the normal pump start up procedures outlined
in this manual. NOTE: FMC can factory prepare units for long term storage for a
nominal fee if specified at the time of order.

Precautions during Freezing Weather
Freezing weather can cause problems for equipment when pumping water-based fluids
that expand in volume when changing from a liquid to a frozen solid state. When water
is left in a pump fluid end and exposed to freezing temperatures, the expansion of the
water as it freezes can rupture the fluid cylinder of the pump and cause equipment
damage. Injury may result when starting equipment that has been damaged.
Whenever the pump is stored or idle in conditions that are near or below freezing, any
water-based fluids should be removed from the pump. The best way to do this is to run
the pump for a few seconds with the suction and discharge lines disconnected or open
to atmosphere. This will clear the majority of the fluid from the pumping chamber as
