Cheaper alternative to CTC Pumps?
This is my first post to this site ever, so please bear with me. I’ve been lurking for about 5 months now and have been very hesitant to post. After reading this forum for some time, I decided to try pumping since I have been getting good results on length, but nothing on girth.
I was going to make a pump using the Mity-Vac setup with the gravel tube, but I ended up with something I think is much better. I know this may sound strange, but, my wife use to breast feed our children and has a Medela “Pump in Style” breast pump. I said, “a pump is a pump” and wondered if this thing would work. The vacuum mechanism was similar to the CTC pumps, would suck and release just the same. I checked the vacuum straight from the tube, minus the breast suction parts, and got between 1 and 10 hg since I could regulate the vacuum. The pump cycles between 40-60 times per minute depending on the voltage input, you can vary that with a adjustable power adapter.
I build a tube using 1 ½ PVC and an end cap. Then drilled two holes in the end cap and attached both of the suction tubes. Both of the tubes have tapered plastic ends, which fit snug into the cap. I’ve been using the pump for about a week with no fluid buildup and the pulsating action feels “very” good. These pumps can be picked up used on ebay for about $100.00-$125.00. This may be a strange setup, but it’s a lot cheaper than a CTC pump.
