<font size="2" face="Verdana, Helvetica, sans-serif">I think you are thinking of packing rather than mechanical seals like the ampmaster would have. These should be completely dry. Darren mentioned pressure as a possible cause of failure. These seals are rated for something like 75-100psi typically. Its pretty quick for the stainless or the elastomers to fail from incompatibilty with salt water. Bio-fouling is more probable. I read on RC that Dolphin was playing with the spring tension of the seal to try and solve nonstarting problems. Perhaps the spring tension is a little too light now. The original pump that dolphin is "branding" doesnt have a choice of seals - there is one that works period. Good luck.

Darren,

If the Mak isn't too loud for you, hook it up and put it to use. Give me a call on my cell tomorrow or PM me.

Scott.. ran it last night for two hours.. actually forgot it was running. It was that quiet.

Well I am going to add to this.

I am not sure of the actual reason this happened or anything. All I know is that my $500 pump is now leaking aroudn the rear seal. I have lots of rust colored salt creep and junk. Whether it is due to running it under pressure due to the bullet skimmer or what I have no clue. All I know is now I need to go buy a new return pump. Grrrrrrrrr

Scott. It's not for sale. lol

very very very very mad..... :mad: :mad:
