Series 7000 mechanical diaphragm metering pump treating sulfuric acid at sanitary landfills: Created for water, wastewater and chemical process applications, the Series 7000 mechanical diaphragm metering pump from the Neptune Chemical Pump Company is being utilized to handle the sulphuric acid used during the nitrification/denitrification process in leachate treatment plants.

The straight-through valve-and-head design of the Series 7000 mechanical diaphragm metering pump allows for improved flow characteristics and the ability to handle corrosive liquids. The pumps can handle viscosities in excess of 5,000 cp and pump capacity can be adjusted through the use of a micrometer dial while the pump is running. The suction lift of the Series 7000 pumps is able to pull the sulfuric acid as much as 25 feet from tank to tank (the equivalent of pulling 45 feet of water).
