Bennett and Tokheim are by far the best internals of any other pumps. Both "heavy weights" and last forever. That is before the planned obsolecence, They both started getting sorry when they started eliminating the stainless cylinder walls on the TOK meters and used steel sleeves and steel pistons on the Bennett meters.
Bennett came out with an aluminum pumping unit about that time....trash, compared to the old ones.
Wayne 2,3,4,5,6 meters had encased ball bearings on the main shaft, stainless internals, teflon cups ( on the 5,6 ), a pleasure to build, compared to a Southwest. We used to rebuild up to 100 G&B (Gilbarco) meters in a week. They wear out the fastest.
