I always kept a Gast vacuum pump in reserve, identical to my primary. This pump can easily run two buckets. I used this pump regularly in my creamery to operate my Hamby bucket washer (still available 9/24). This pump needs a 3-way manifold for its top port for a vacuum gauge, hose barb, and vacuum regulator (see https://hambydairysupply.com/vacuum-regulator-for-nupulse-pumps-3-8-npt/). I have a new vacuum regulator to include.
