Nalge vacuum hand pump, 36cc - Nalge Nunc Vacuum Pump Hnd Op W/GAUGE36CC 6132-0020 Vacuum Pump Hnd Op W/GAUGE36CC

I had high hopes that this pump would be a good one to use for milking my goats. It displaces 36cc of air, rather than the 15cc pump I currently use. The trade-off was that the 36cc pump is harder to pump; in fact, it was so hard to pump that after just 3 days of using it, the handle broke while pumping. I think it has a slight design flaw in the handle. The handle needs to be a little thicker; or the pump a little easier to pump. If these issues were resolved, I still think it would be good to use for milking.
