Kosmo Series

Summary

Product identification

• Product Line: Kosmo Series
• Type: Mechanical-return diaphragm dosing pump
• Models: MM1 and MM2
• Description: Electric motor-driven pumps with mechanical diaphragm liquid ends and mechanical return, designed for continuous operation. Features a PTFE diaphragm directly linked to the mechanism's moving parts, allowing for high suction head conditions. All mechanism parts have permanent lubrication using ball bearings to prevent overheating, extend pump life, and ensure low decibel operation.
