Mechanical Metering Pumps

Neptune's Mechanically-Actuated Metering Pumps are engineered from the ground up to be more robust and durable than other mechanical diaphragm pump designs. Incorporating the ruggedness of a hydraulic metering pump, Neptune’s mechanically-actuated metering pumps eliminate the need for intermediate fluid or hydraulic oil to actuate the diaphragm. This reduces the potential for gearbox oil to contaminate the process. 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 industrial and municipal water and wastewater treatment, chemical processing and agriculture.
