: : Question???
: : Is anyone out there using varible speed drive on their Electric Boiler Feed water pumps ? We have one that is always blowing the mechanical seals.
: : The main Boiler Feed water pump is steam driven and we don't seem to have a problem with it. Is anyone else having more trouble with their Electric Driven Boiler Feed water pump seals.

: Are your seals rated for the temperature at which they are running? also are the cooling lines clear I had a similar problem and put small 5 micron cartridge filters on the cooling lines I havn't had a seal fail since
