Neptune Chemical Pump - a PSG Dover Brand products

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.

The Neptune Electric Stroke Control allows the capacity of any Neptune Series 500 or Series 600 `dia-PUMP` to be automatically controlled in response to a standard 4-20 mA process signal. Also accepts 0-5 VDC/0-10 VDC signal or digital pulse train inputs. One-piece controller- positioner mounts directly to the pump. No machining or any special drillings or tappings needed to retrofit pump. Ideal for water/wastewater, power and process industry applications...anywhere that pump flow must be automatically proportioned or varied.

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 are possible with mechanical diaphragm pumps. Explosion-proof models are available for use in hazardous atmospheres

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.

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.

Neptune™ 7000Z Series metering pumps handle clear liquids with viscosities ranging from water-like to 2,500 cPs.
