Dual row pad plungers are one of the best-selling plungers on the market. The spring-loaded pads press against the wall of the tubing, creating an effective seal. This seal allows efficient use of the available gas energy to surface the liquid column. Padded plungers offer excellent efficiency, seco [..]
