NEPTUNE: Mechanical Diaphragm Metering Pumps
Neptune Chemical Pump Co., Inc. has broadened its line to include the new Series 7000 mechanically actuated diaphragm metering pumps. Neptune's Series 7000 pumps are capable of handling viscosities in excess of 5,000 cps and can pump chemicals that off-gas (sodium hypochlorite) without binding. All models in the line are self-priming and provide suction lift to 20 feet. Maximum capacities range from 15 gph to 300 gph at 150 psi, depending on model. The Series 7000 is available as seven models, with one of two liquid-end diaphragm diameters (100 mm and 200 mm) and one of four gear speeds (18, 37, 72 and 117 SPM). The pumps feature 10-1 turndown by micrometer dial, and a variable-speed option allows for greater turndown range and automated flow control.
