Neptune: Metering pumps in irrigation systems

Neptune_Chemigation-30These systems have been designed for the application of fertilizers, herbicides, fungicides, insecticides and other strong chemicals. The chemical tanks have a sloped bottom for complete drainage and ease of cleaning. All tanks larger than 55 gallons are fitted into double-wall containment and with double wall injection lines to protect the environment. A cover shields the pump, piping and electrical controls from the elements and excludes rain and debris, which allows 100% reclaim of uncontaminated chemical in the event of a spill or broken line.

The Series 500 metering pumps are highly accurate, repeatable and provide flow rates that are easily adjustable, allowing growers the flexibility to adjust to changing growing conditions. These pumps feature valve cartridges that can be removed for cleaning without disturbing the piping to the pump and a Variable Oil By-pass stroke adjustment that allows for better valve performance. This allows the valve checks extra time to seat even in heavy liquids since they are idle during the by-pass portion of the suction and discharge strokes.

Series 500 pumps are available with special pump heads to allow for pumping thicker liquids and suspensions. The pumps have capabilities to 100 gph (378.5 l/hr) simplex and 200 gph (757 l/hr) duplex at pressures up to 3,000 psi (210 kg/cm).
