Horizontal End Suction Pump for Chemical Process, ASME B73.1-2001
Installation, Operation, and Maintenance Manual – CPP21
• Always drain the oil before moving the pump, to avoid any damages, and refill
the motor on its new location.
6. Rotate the shaft of the motor once a month.
7. Some form of heating must be used to prevent condensation. This heating should maintain the winding
temperature at a minimum of 9 °F (5 °C) above the surrounding ambient temperature. There are three
options:
o If space heaters are supplied, they should be energized.
o If none are available, single phase or “trickle” heating may be utilized by energizing one phase of the
motor’s windings with a low voltage, producing heat in the winding conductor.
• Request the required voltage and transformer capacity from the driver
manufacturer.
o A third option is to use an auxiliary heat source and keep the windings warm by either convection or
blowing warm dry air into the motor.
• Be careful not to overheat, since keeping the temperature of the motor frame
9 °F (5 °C) above the surrounding ambient temperature is sufficient.
After the storing period, follow the next steps as start-up preparations:
1. Motor should be thoroughly inspected and cleaned to restore to an “As Shipped” condition.
2. Motors, which have been subjected to vibration, must be disassembled and each bearing inspected for
damage.
3. Oil and/or grease must be completely changed using lubricants and methods recommended on the
motor's lubrication plate, in the “LUBRICATION” section of the driver manufacturer’s manual.
4. If storage has exceeded one year, the motor manufacturer’s Quality Assurance Department must be
contacted prior to equipment start-up for any special recommendations.
3.5 CONSERVATION
All exposed, machined, working surfaces (flanges, seals, surfaces supporting the motor), shaft ends, unpainted
couplings and the like have been cleaned and treated with anticorrosive agents. After being cleaned, all parts
inside the pump housing have been sprayed with anticorrosive agents.
The period of protection offered by these conservation measures is approximately 18 months if stored in a dry
