Kosmo MM1 Series

Mechanical-return diaphragm dosing pumps


Representing one of our most flexible chemical dosing solutions, the Kosmo range of motor-driven diaphragm pumps offers consistently accurate and reliable performance in applications as diverse as reverse osmosis, cooling water and potable water treatment. 


Superior operation across a range of flow rates up to 2,300 l/h means the fully-reciprocating Kosmo is particularly suited to water-treatment applications requiring a low flow rate.



Meanwhile, high-grade 316L stainless steel, PVC and PVDF components provide outstanding chemical compatibility and an optional cast aluminium housing offers a lightweight yet strong, durable alternative.


Kosmo’s permanently-lubricated mechanism includes ball bearings for the principal moving parts, helping to prevent overheating and delivering quiet running even during continuous operation.
