For sale is a Pair of Gorman Rupp (GRI) Model 16001-125 Compact Bellows-Type Metering Pumps. 1/60/115V, Single phase AC input power. Stroke (displacement) adjustment from 0 to 100%. These pumps will come mounted on a non-magnetic metal base. I have done a basic power-on test of each pump; they sound good and appear to be working correctly. They were removed from operation at a local shop that has closed-down.
