Chemical Feeder Manufacturer Case Study
Gregstrom was asked to manufacture a chemical feeder that prepares and dispenses chlorine for disinfecting municipal and large commercial water systems. Producing a complex, integrated system like this might seem challenging, but Gregstrom provided a complete solution, from design assistance and Made in USA manufacturing to component sourcing, product assembly, and testing.
The chemical feeder consisted of six rotomolded parts, one vacuum formed part, and 160 other components. Gregstrom rotomolded the lid and hopper with molded-in graphics, a parts decoration technique. Gregstrom also rotomolded the plastic pallet that was used to hold the hopper and ensured that all wetted components were made from NSF-approved materials.
For this project, the plastic hopper held 220 pounds of chlorine briquettes and the plastic base held 32 gallons of the chlorine solution. Both the hopper and the base were rotomolded in LLDPE plastic as double-wall containers. The pallet attaches through molded-in inserts and holds the hopper and base mixing unit, the pump, and all the plumbing and electronics controls.
In addition, Gregstrom purchased, tested, and assembled various injection-molded and blow molded parts along with electrical and plumbing components. Finally, Gregstrom tested the chemical feeder according to plumbing and electrical standards. This added even greater value and further demonstrated the ability to successfully manage complex projects.
