2.0 Storage Instructions
Proper storage of your FMC pump will ensure that it is ready for service when needed.
Follow the guidelines below that fit the requirements of your application.
FMC pumps come from the factory without crankcase oil and are prepared for storage
periods of up to six (6) months in proper environmental conditions. Indoor storage in a
dry, temperature-controlled location is always recommended. If pumps are to be stored
short term (less than six (6) months) in a severe environment, they should be prepared
using the procedures outlined in the “Short Term Storage for Severe Environments”
section 3.2 below. Remember that any fluid that poses an environmental hazard or is
toxic must be handled and disposed of properly.
2.1 Short Term Storage
If the pump is stored in an indoor, temperature controlled environment for less than six
(6) months, no special steps are required to prepare it for storage. As a general rule for
pumps in corrosive fluid applications, the fluid end should be drained, flushed with water
or other non-corrosive cleanser and compressed air used to blow dry whenever idle.
2.2 Short Term Storage for Severe Environments
If the pump has been in service, drain any fluid from pump fluid end, flush the fluid end
with water to clean out any of the remaining pumpage and blow dry with compressed
air. Pour 1/4 cup of internal rust inhibitor oil described in Table 2, into the suction and
discharge ports of fluid end, and then install pipe plugs in openings. Drain the power
end (crankcase) oil and remove the oil fill pipe plug. Pour ¼ to ½ cup of internal rust
inhibitor oil described in Table 2, into the oil fill hole and then install the filler pipe plug.
Coat all exposed, unpainted metal surfaces (for example, Driveshaft) with preservative
oil. Replace the oil fill cap, and then cover the entire pump with a weather resistant
covering such as a canvas or plastic tarp or bag.
2.3 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, filler
pipe plug, 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.
2.4 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 or ceramic cylinders of the pump and
