Prepping the pump for operation after removing from long term storage (> 3 months):
Prior to attempting to operate a pump that has been in storage for greater than 3 months, it is recommended
the following sealing elements at the least be replaced:
Discharge flange lip seals
Suction cover, discharge cover, and gauge connection lip seals
All packing header and pressure rings
Stuffing box adapter seals
The following sealing elements shall at the very least be removed and carefully inspected for damage and
replaced as required:
Packing nut o-rings
Packing nut wiper ring
Suction manifold o-rings
Refer to
Section 6
for start-up procedures.
If your pump has been in service:
For the Fluid End:
If the unit has been in service and will be stored for more than a couple of weeks, remove the valve covers
from the fluid end and blow all moisture out with dry, compressed air. Wear proper protective gear while
blowing out moisture to prevent contact with the well service fluid. Generously mist the inside of the fluid
end with a suitable lubricant to displace trapped water and create a protective film on the metallic
components. Replace the valve covers. Seal off all inlets and outlets with plastic sheet and tape or with
mechanical blind seals.
CAUTION
: Well service fluid will be trapped between the inlet and outlet valves
and will spill out when removing the suction valve covers. Preparation for spillage is important for safety
and environmental reasons. A catch pan and appropriate absorbent materials will be needed.
For the Power End:
If the pump has been in service, moisture from humidity can enter through the oil cap/breather and will
accumulate at the inside bottom of the power end. If this occurs, remove the back access panel (See
Section
11.4
) and wipe out the accumulated moisture with a suitable absorbent.
Do not use granulated absorbents
inside the pump
. Replace the back cover after moisture has been removed. To further protect the pump
from humidity while in storage, especially when stored near large bodies of water or in areas of high
humidity, use duct tape to seal off the oil cap/breather. Sealing in this manner will be more effective if the
air inside the pump is warmer than outside air prior to sealing the oil cap/breather. If the cap on the
lubricating oil reservoir is a breather style cap, it should also be sealed at this time.
Outdoor Storage:
If the used pump is to be stored outdoors, it should be placed in a covered location that will protect the
pump from direct exposure to moisture and sunlight. If a covering is not available, the pump should be
covered and tied with a heavy duty tarp.
