SVCN 7 INSTALLATION, OPERATION, & MAINTENANCE
WARNING
Operation of the unit without correct lubrication can
result in overheating of the bearings, bearing failures,
pump seizures and actual breakup of the equipment
exposing operating personnel to physical injury.
5. Check oil level in bearing housing.
6. Ensure that the bearing oil temperature is within its normal operating range of 140 to 160°F
(60 to 71°C). At no time should the bearing oil temperature exceed 180°F (82°C).
7. Check for adequate flow of cooling liquids.
3.4.6 SECURING THE PUMP
The pump should be shut down rapidly to protect the internal wear parts which are lubricated by the
liquid being pumped.
1. Shut down driver in accordance with the manufacturer’s instructions.
CAUTION
If pump stops abruptly when driver is shut down, investigate
for pump binding. Take necessary remedial action before
resuming operation.
2. Close the pump discharge valve. The pump suction valve should be closed only if required by
system operation or maintenance.
3. Close valve in bypass line
4. Turn off cooling liquid.
5. If pump is subjected to freezing temperatures, it must be drained of liquid to prevent damage
to the pump.
Before being put on the line (that is, started), the pump requires an external inspection for operational
readiness and lube oil servicing; additionally, valves and auxiliaries that are pertinent to pump
operation must be set up.
3.5 GENERAL MAINTENANCE
These pumps have been designed to simplify maintenance and make service easy. Preventative
maintenance and overhauls before serious troubles occur will reduce operating costs. The following
section outlines the various steps necessary for the removal and replacement of all parts. If an
overhaul is required, follow the specific instructions carefully. Contact the factory if additional
information is needed.
3.5.1 ROUTINE MAINTENANCE
NOTE
This schedule is a recommendation only and is intended to
be amended by site experience of the prevailing conditions.
