Neptune debuts new diaphragm metering pump

Pump manufacturer Neptune, a Dover company, has introduced its new Series MP7100 mechanically actuated diaphragm metering pumps.

The Series MP7100 is engineered from the ground up to be more robust and durable than similar mechanical diaphragm pump designs.

It incorporates the ruggedness of a hydraulic diaphragm metering pump, eliminates the need for intermediate fluid or hydraulic oil to actuate the diaphragm, and reduces the potential for gearbox oil to contaminate the process, the company says.

The result is a pump design that provides reliable and accurate dosing of a wide range of mild to aggressive chemicals, including those used in municipal water and wastewater treatment.

The gears of the Series MP7100 pump operate in an oil bath for longer life while its finned gearbox design dissipates heat more efficiently.

The pump has a maximum capacity range up to 1,041l/h, pressures to 16 bar, and a suction-lift exceeding 6m on water-like chemicals.
