Neptune Chemical Pump has released the Series 7000 mechanical diaphragm metering pump, designed for water, wastewater and chemical-process applications. The pump has been designed without the need for contour plates on the liquid side of the diaphragm. This straight-through valve-and-head design allows for improved flow characteristics and the ability to handle corrosive liquids. The pumps can handle viscosities in excess of 5000 CP and pump capacity can be adjusted through the use of a micrometer dial while the pump is running. In addition, the suction lift of the pump is capable of pulling sulfuric acid as much as 25ft from tank to tank (the equivalent of pulling 45ft of water).The sealless design of the pump eliminates the catastrophic breakdowns that can plague other pump types.
