Goulds Pumps VIT - IOM - Manual (Page 41)

Install a solid-shaft driver
WARNING:
• When installing in a potentially explosive environment, make sure that the motor is properly certified.
• Do not test the motor for direction of rotation when it is coupled to the pump. If the pump rotates in
the wrong direction, serious damage to the pump, motor, and personnel will result.
• Do not work under a heavy and suspended object unless there is a positive support and safeguards
that will protect you if a hoist or sling fails.
NOTICE:
• When the pump is supplied with a thrust pot, do not secure the driver to the discharge head until after
the thrust pot and flexible coupling are installed. A separate supplement for thrust pots will be
furnished as required.
• Read and follow the motor manufacturer's instructions before lubricating the motor bearings.
Excessive lubrication can cause the bearings to overheat and fail prematurely.
The coupling between the driveshaft and the discharge-head shaft can either be a non-spacer type or a
spacer type. The spacer type is used on pumps furnished with a mechanical seal to permit servicing of the
seal without the removal of the driver.
