Neptune Series 500 "dia-Pump" Metering Pumps

Variable Oil By-pass™ stroke adjustment allows better valve performance than variable linkage designs. The valve checks have extra time to seat even in heavy liquids since they are idle during the by-pass portion of the suction and discharge strokes.

Neptune Series MP7000 Mechanically Actuated Diaphragm Metering Pump

The Series MP7000 Mechanically Actuated Diaphragm Metering Pump is the low-flow version of the MP7100 metering pump. The MP7000 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 result is a pump design that provides reliable and accurate dosing.
