Series MP7000 mechanically actuated diaphragm metering pumps from the Neptune Chemical Pump Co., part of PSG, a Dover company, are designed for water and wastewater applications. The self-priming pumps have a maximum capacity of 275 gph and pressures to 235 psi. The pumps feature a metallic, corrosion-resistant gearbox, oversize check valves to improve performance (minimum friction losses), bronze gears for quiet running and longer service life, suction lift capacity exceeding 20 feet on water-like chemicals, and the ability to handle viscosities in excess of 2,500 cps.“There are applications that are above the normal 100-150 psi maximum capabilities of most mechanically
