Mechanical Return Diaphragm Dosing Pump – Seko Kosmo MM1 Series

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.

MM1 pumps are electric motor-driven pumps with mechanical diaphragm liquid ends and mechanical return. Kosmo MM1 can be used effectively in applications where multiple heads are required and can be used with up to three identical or different liquid ends. The pump can handle flow rates of up to 530 l/h at pressures of up to 12 bar and at a maximum working temperature of 40°C.
