A couple old pumps, a drill powered jobby and a hot water recycling grundfos pump. Gone through two of the grundfos jobs and both caught fire, they did work well when set up nicely and close attention was payed to them, I brewed a hell of a lot of beer with them. The drill pump now leaks a bit to much but could possibly be rekitted with seals. I'am just waiting till the bank account says i can have a march pump untill then its all gravity and the herms system isn't used at all anymore.
