Proper preparation

Rotation of the pump and bowl

assembly shaft

• Rotate the pump and bowl assembly shaft counterclockwise

once a month, at a minimum.

• Never leave the shaft in a previous position or in the extreme

raised or lowered lateral position.

• Make sure that the shaft rotates freely.

Controlled storage facilities

• Maintain an even temperature of 10°F (6°C) or higher above

the dew point.

• Keep the relative humidity to less than 50%.
• Make sure that there is little or no dust.

Uncontrolled storage facilities that have

uneven temperatures, higher humidity,

and/or dusty conditions)

• Inspect the pump periodically to make sure that all

preservatives are intact.

• Seal all pipe threads and flanged pipe covers with tape.

When pump is not in regular operation

If a pump has been installed, but is not in regular operation for an extended period of time, such as during
a seasonal shutdown, then operate it for at least 15 minutes every two weeks, if possible.

Prepare the pump for long-term storage

For storage periods over six months, you must follow the pump storage requirements and this procedure:
1. Inspect the lube-oil and seal-flush piping and either fill the piping with rust-preventative oil, or recoat

the piping periodically in order to prevent corrosion.

2. Place 10 lbs (4.5 kg) of moisture-absorbing desiccant or 5.0 lbs (2.3 kg) of vapor-phase inhibitor

crystals near the center of the pump.

3. If the pump is assembled, place an additional one pound (0.5 kg) in the discharge nozzle and securely

fasten the nozzle to the discharge elbow.

4. Install a moisture indicator near the perimeter of the pump.
5. Cover the pump with black polyethylene with a minimum thickness of 6.0 mil (0.15 mm), and seal it

with tape.

6. Provide a small ventilation hole approximately 0.5 in. (12.0 mm) in diameter.
7. Provide a roof or shed shelter in order to protect the pump from direct exposure to the elements.
