Electronic diaphragm metering pumps. Operates on any single phase voltage from 94 VAC to 264 VAC. Manual, 4-20 mA or water meter pulse controlled.
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 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. Discharge pressures are higher than...
Neptune Series 500 tubular diaphragm pumps are engineered for viscous fluids up to 20,000 cP and for medium slurries up to 10% solids.
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...
The Neptune Series 7000 "dia-PUMP" is a mechanically actuated diaphragm metering pump designed for water, wastewater and process applications. The mechanical design eliminates the use of contour plates on the...
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...
