The Neptune Series MP7100 is a mechanically-actuated diaphragm metering pump engineered from the ground up to be more robust and durable than similar mechanical diaphragm pump designs. The MP7100 pump incorporates the ruggedness of a hydraulic diaphragm metering pump, eliminates the need for intermediate fluid or hydraulic oil to actuate the diaphragm and eliminates the potential for gearbox oil to contaminate the process since it has an oil free gearbox design.
The straight-through flow design of the MP7100 liquid end and the elimination of the contour plate result in improved flow characteristics, making the pump well-suited for pumping difficult chemicals such as viscous fluids, shear-sensitive fluids and fluids with suspended solids.
