Pump start-up

WARNING:

Start-up precautions

• All equipment and personal safety related devices and controls must be installed and
• To prevent premature pump failure at initial start up due to dirt or debris in the pipe system,
• Variable speed drivers should be brought to rated speed as quickly as possible
• Variable speed drivers should not be adjusted or checked for speed governor or over
CAUTION: When starting the pump, immediately observe pressure gauges. If discharge
pressure is not quickly attained, stop driver, reprime and attempt to restart.

Bearing lubrication

Bearings must have adequate lubrication. Engage external lubrication system. Consult
"Bearing section" of these instructions for specific information.

Shaft rotation

The pump shaft must turn without any binding or rubbing. By manually turning the rotating
element, only the uniform frictional drag of the bearings and the stuffing box should be sensed.
CAUTION: Serious damage may result if the pump is run in the wrong direction

Correct rotation of the driver

The direction of rotation of the driver must be checked before it can be coupled with the pump.
The direction of rotation of the pump is indicated in a prominent location. For pumps with
impellers threaded on the shaft, reverse rotation would back the shaft from the impeller thread.
Considerable damage may occur.
Lock out driver power to prevent electric shock, accidental start-up and physical injury.

Service temperature in an ATEX classified environment is limited to the area
classification specified on the ATEX tag affixed to the pump (reference Table 1 in the
ATEX identification section).
The coupling used in an ATEX classified environment must be properly certified.
The coupling guard used in an ATEX classified environment must be constructed from
a non-sparking material.
operating properly.
ensure the system has been adequately cleaned and flushed.
speed trip settings while coupled to the pump at initial start up. If settings have not been
verified, uncouple the unit and refer to driver manufacturer's instructions for assistance.
Pumpage temperatures in excess of 93°C | 200°F will require warmup of pump prior to
operation. Circulate a small amount of pumpage through the pump until the casing
temperature is within 38°C | 100°F of the pumpage temperature and evenly heated.
