Diaphragm metering pumps for accurate chemical dosing

Diaphragm metering pumps for accurate chemical dosing

Neptune’s,  MP7000 mechanically actuated diaphragm metering pump has design features that provide reliable and accurate dosing of chemicals, including those used in industrial and municipal water and wastewater treatment, chemical processing and agriculture.

Engineered from the ground up to be more robust and durable than similar mechanical diaphragm pump designs, the series 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 pumps also feature a finned gearbox that dissipates the heat created during normal operation more readily than other designs, oversized check valves that improve performance and minimize friction losses, and rugged bronze gears for quite-running and long service life. Additionally, the straight-through flow design of the Series MP7000 liquid end and the elimination of the contour plate results in improved flow characteristics, making the pump the ideal solution for pumping difficult chemicals such as viscous fluids, shear-sensitive fluids and fluids with suspended solids.

The pumps feature capacities to 27 gph (102 lph) at operating pressures up to 235 psi (16 bar) and include a 10:1 turndown via micrometer-type knob with a high-contrast, easy-to-read scale. Series MP7000 pumps are also available with a self-loading micrometer that prevents drift.
