A/C pump B/O?

[biggerseagar]

Hi folks...


Turned my a/c heat on today and could not get a water flow going. Pump got very warm and so I check to see how far the water was getting to and it ended at the pump. Took the top hose off ( the long hose going to the a/c unit) and no water at all.

I have a 2001 Maxum 3000 SCR and the model number on the pump is a PML 500L. Serial # M99 0177- volts 115 and amps 2.0 - Hz 60 It is a Talyormade pump with the cruisair name stamps on it too.

Where is the best place to order one of these babies?

Thanks

Roger

I'd probably call up a local bayliner store..it's a common pump..try greatlakesskipper or fisheriessupply.com...but sometimes you just need to prime the pump....pour water or stick a hose in the exhaust end of the pump...where it feeds out of the side of the boat......let it run for a few seconds and then pull the hose and start the system up..should pump the water thru the system then...
or contact the ARRRR company...

There is a company out of Chicago that sells the rebuild kit for around $50, I am sure they sell the whole pump also. They were the least expensive and had it in stock. I will check my e-mail on my office computer tomorrow and let you know who it is.
Those pumps are very simple, but they cannot deal with much head pressure or suction problems when starting up.

Thanks everybody..............I went ahead and ordered a the PML 500 from Greatlakes Skipper. $350.00 ouch!

SP....... I took it out of the boat and tested it with a bucket of water and it was bad, won't work. I have never had to prime it whatsoever, since owning the boat. I would turn the unit on and water would come out of the front hole all the time.

Again thanks!!

no, no..... the old one is fine..... its just a turbine blade fan.

It must be primed to work, so you use the garden hose to push all the air thru the system becasue the pump is not self priming.

Also, you can but just the pump head for $160 bucks, the motor is like an oil sowing machine....

That's exactly what I was thinking! Like I said I bought the rebuild kit for a 1/4 of the pump price. This pump is used in a lot more than marine applications, and can be bought (if necessary) for a lot less than marine prices!

I have to prime mine every season with a garden hose. Water needs to be well past the pump. With no water running through it, I would expect it to get warm. Then again, it's a pump and they don't live forever.

Same thing happened to me when I cleaned the sea strainer, loosened the exhaust side, open the sea stariner valve and it pushed the air out of the pump and was fine.
