Mechanical Seal
• Mechanical seals require no special attention. If leakage
occurs investigate the cause and replace the seal
following the makers recommendations, then realign the
pump and motor shafts.
• Do not run the pump unless properly filled with water as
the mechanical seals need a film of liquid between the
faces for proper operation.
• Mechanical seals may 'weep' slightly at start-up. Allow
the pump to continue operating for several hours and
the mechanical seal to 'seat' properly prior to calling for
service personnel.
caution
Do not use oil, Vaseline or other petroleum or silicon
based products for seal elastomer lubrication.
Otherwise elastomer swelling may occur, causing
seal failure. Recommended: International Products Corp
p-8 0 Rubber Lubricant Emulsion in www.ipcol.com
caution
The permissible tds levels are :
a SSiC Vs C – 2000ppm max
b SSiC Vs SSiC – 40 0 0ppm max
In case the water exceeds permissible tds levels, corrosion
or fouling may occur resulting in seal failures. It is necessary
to maintain the water quality with proper water treatment
program.

system cleanliness
• Before starting the pump the system must be thoroughly
cleaned, flushed and drained and replenished with clean
liquid.
• Welding slag and other foreign materials, "Stop Leak" and
cleaning compounds and improper or excessive water
treatment are all detrimental to the pump internals and
sealing arrangement.
• Proper operation cannot be guaranteed if the above
conditions are not adhered to.
