FINISH THOMPSON INC.: The DB Series magnetic drive pumps reportedly operate at up to 70% efficiency with broad hydraulic coverage. Impeller diameters are evenly spaced for more precise coverage. The pumps offer higher working pressure capabilities, which allow high specific gravity fluids (1.8+ SG) to be pumped safely. According to the company, the pumps are precision engineered to sustain a long life cycle in the most aggressive, corrosive environments. Additionally, high hydraulic efficiency significantly reduces energy consumption. Call 814.455.4478 or visit .
