Since March, the Hydra-Cell Metering Solutions pumps (photo) are available with Alfas diaphragms as well as brass manifolds. Aflas is a copolymer elastomer that is resistant to extreme heat, acids and alkalis. It is appropriate for use when pumping water or alcohol, and in various chemical environments. Brass provides a lower-cost alternative to stainless steel and Hastelloy when the higher discharge pressures of a metallic pump head are required, the company says. The Hydra-Cell Metering Solutions line includes six models with maximum flow capacities from 26.5 to 894.6 gal/h and maximum pressure ratings from 1,000 to 2,500 psi. — Wanner Engineering, Inc., Minneapolis, Minn.
