Hi Mike - if it is the 2500 Cal pump with a rounded handle on the top and 3 small screws on the bottom to hold on the "intake" plate, I had a major problem with them this year and last (sold 10 and had 6 returned under warranty), even the one in my own pond started humming loudly (a first for a submerged pump that I know of) and quit - I no longer sell them and replaced my own with a Beckett 1800 JME - Gale :~) "Mike Patterson" <mikepatterson@spamtrapmindspring.com> wrote in message news:b7g4h3d302r1f1f2aem53casd2aq8nf71s@4ax.com... >I have a Cal Pump PW 2500 that's been running 24x7 for about 2 years, > and last week it stopped. > > It had no clogging or blockage, either external or internal, so I took > off the impeller chamber and found no blockage there. > > The impeller won't turn under power, and while I can turn it by hand, > it's not easy and more or less free-spinning as it should be. > > The motor emits a humming under power but that's all. > > The motor appear to be a sealed affair, and I'm wondering if there are > any repairable parts inside to make it worth dismantling further. > > A new pump is about $130 shipped, and I'd rather not spend the money > if I can just replace a carbon brush or something. > > Anyone have any experience with this? > > Thanks! > Mike > Mike Patterson > Please remove the spamtrap to email me. > "I always wanted to be somebody...I should have been more specific..." - > Lily Tomlin >
