Hydra-Cell Industrial Pumps, a business of Wanner Engineering, introduces the H25 Metering Series Industrial Pumps. These hydraulically balanced diaphragm pumps are engineered to pump some of the toughest solutions imaginable at up to 1200 gpm, while providing +/- 1% steady state accuracy with a 10:1 turndown ratio, at a fraction of the cost of conventional precision metering pumps. The H25 Metering Series operates smoothly and quietly while requiring less horsepower than most pumps of comparable size and capabilities. Their rugged design can operate at 1000 psi, but they can also meter with the same degree of accuracy at 50 psi. These pumps can run dry without damage and have no troublesome cups, packings and seals, resulting in fewer problems, less maintenance and longer pump life. They are available in a variety of construction materials.
