Just wondering if anyone has used electric pumps and how well they work pumping pussy and cocks. If they work well are there any you can recommend?

Hello Jekyl,

I used electric pumps originally designed for breastfeeding (lactating) mums. The one I have is probably a bit powerful and can produce up to -0,5 bar (7 psi) vacuum. On one occasion the nipples of the sub started bleeding slightly. I may have to install a leak valve to control the pressure better. To do that I plan to do some measurements using a pressure gauge. The missing part is currently the hose adapter to the gauge.

Hope this helps,
Chris

Look online for a fish tank pump, you make small modification to the pump inside to vac instead of pump air, very easy. Should pull about 5-6 in of vacuum, perfect for pumping, you can even get one with a built in valve.
I have had good luck with a Rena Air 300 Air Pump
