Split impeller

[Slick Fork]

No extra pumps that would work unfortunately.

Send me a pic of how the pump hooks up Chris, I might have a pump you could use until you find an impeller.

Here's a shot of it out of water, the connection to the skimmer body is metric, a 1" female is too big and a 3/4" female is too small. The connection is about 5 and 1/4" up the body of the skimmer.

Reading now that the "IN" series by vertex is discontinued in favour of their upcoming omega series, doesn't bode well for replacement part hunting.

You could do a mod and add a 90* hose fitting & glue it into the water inlet, then use a Dc5000 pump & a little bit of hose. I will have a look when I get home from my job tomorrow & see if I have anything that might work.
