Reprinted from CHEMICAL ENGINEERING Submerged in acidic wastewater for years, these polypropylene pumps are still thriving When estimating the potential life of severe-service process pumps, design engineers often think in terms of years, not decades. Back in 1977, Dyno Nobel (Carthage, Mo.) — owner of the last remaining dynamite plant in North America — selected

Reprinted from World Pumps Guide to the selection of materials for pumping NaOH and NaOCl This third article in an on-going series on the selection of materials for pumping corrosive, abrasive and hazardous chemicals considers the challenges presented by the caustic alkali sodium hydroxide and its close relative sodium hypochlorite. George Black looks at the

Chemical plants and municipalities rely on thermoplastic pumps for odor control, corrosion resistance and reduced maintenance. A recent study conducted by Pollution Engineering revealed that approximately 40% of the respondents use nonmetallic pumps at their facilities… even more significant, approximately 30% expected the number to increase over the next three years. The primary reasons for
