Pump Modification

Since the beginning, the pump was, to me, going to potentially let down the entire project. I really had my doubts as to how I could make it fit in, look good and still be functional. The whole shape and grey colour of Eheim pumps clashed with all of my ideas - but I had read that these were (arguably) the best pumps to get and being a water-cooling first-timer I got one. While surfing the Aqua Computer site I noticed the \'Full Metal Jacket\' enclosures there (designed to stop EMI from the pump), however, not being able to read German I wrote to Pug at Wizard Designs who is the UK\'s Aqua Computer guru.

Pug had the FMJs but informed me that they weren\'t made for the Eheim 1250, which was larger than both the 1046 and 1048 models that had enclosures available. Fortunately he got into the spirit of what I was trying to do and sent some pictures and his thoughts. Thanks to these I decided it would be possible to mod the pump to fit and Pug sent one to me. Most folks would have just said you couldn\'t do it and I would have given up on the idea, but thanks to Pug\'s pics and enthusiastic support the challenge was on!

I started by stripping every piece of extraneous plastic from the pump itself - feet, inserts, the rear cover and silver front cover. The rear cover had to be levered off with a screwdriver after removing all the feet and inserts. I then got out a big, chunky file and filed...

... and filed some more. All necessary to accommodate the bottom part of the enclosure which sits inside the top part. It was narrower than the pumps dimensions. I was cutting it fine with scant millimetres to play with. I still needed more...

I removed the plastic ring that locks the front part of the pump in to get at the little tabs - they were blocking the top cover from sliding down.

A pair of pliers neatly removed them with a twist, as it did for the plastic ribs around the intake - also interfering with fitting the cover.

Back in place - nothing untoward sticking out anymore.
