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.
