Viking Pump TSM341.1: SG Mag Drive Series - Manual (Page 18)

SECTION TSM 341.1 ISSUE J PAGE 18 OF 19
MAINTENANCE:
1. DO make sure any pump that has residual system
pressure in it or that has handled high vapor pressure
liquids, has been vented through the suction or discharge
lines or other openings provided for this purpose.
2. DO make sure that if the pump is still hooked to driver
while maintenance is being performed that the driver
has been “locked out” so that it cannot be inadvertently
started while work is being done on the pump.
3. DO make sure any pump that has handled a corrosive,
flammable, hot or toxic liquid has been drained, flushed,
vented and/or cooled before it is disassembled.
4. DO record pump model number and serial number and
file for further use.
5. DO obtain, read and keep all maintenance instructions
furnished with pump.

Comments:
6. DO provide pressure relief valve for discharge side of
pump.
7. DO check for proper rotation as indicated on nameplate.
8. DO use piping, hose and fittings rated for maximum
system pressure.
9. DO check to make sure all guards are in place.
10. DO handle magnets with extreme caution remembering
they will attract to any ferrous objects.
Operation:
1. DON’T run the pump (or coupling especially) at speeds
faster than shown in catalog for that size.
2. DON’T allow the pump to develop pressure higher than
those shown in catalog at that size.
3. DON’T expose the pump to coupling or temperatures
above or below limits shown in catalog for that design or
specific construction.
4. DON’T operate unit without all guards in place.
5. DON’T operate pump without a pressure relief valve in
discharge piping; be sure the valve is mounted and set
correctly.
6. DON’T operate the pump with all the liquid bypassing
through the internal pressure relief valve or without any
flow of liquid going through the pump for more than 30
seconds. Operation under either of these conditions may
result in a heat build up and damage to the pump or
coupling.
7. DO have spare parts, pump or complete standby unit
available, particularly if the pump is an essential part of a
key operation or process.
