The Neptune Series 7000 "dia-PUMP" is a mechanically actuated diaphragm metering pump designed for water, wastewater and process applications.

Neptune Model 481-S and 501-S hydraulic diaphragm metering pumps are built to deliver very low flows, repeatable and accurate ranging down to quarts per day.

Series 500-E offers an economical alternate to the standard Series 500 "dia-PUMP" or an opportunity to "step-up" from packed plunger pumps to a true hydraulic diaphragm pump at a modest cost increment.

Neptune high viscosity, flat diaphragm "V-Pumps" are designed to accurately meter viscous fluids up to 5000 cP such as polymers and other thick liquids.

Neptune Series 500 tubular diaphragm pumps are engineered for viscous fluids up to 20,000cP and for medium slurries up to 10% solids.
