DELLMECO DME (Electro-Mechanical Operated Double Diaphragm Pump) is a positive-displacement pump that transfers fluids by means of diaphragms operated by linear mechanism, which is being moved by electric motor. The casing in contact with the fluid is made of PE conductive (R…), PTFE conductive (Z…), Aluminium (A..), AISI 316 (S..), Cast Iron (C..), or AISI 316L (H.., Hygienic Stainless Steel). This pump is designed for the pumping of liquids, highly viscous and solid substance-containing media, as well as fluidizable powders.

Compressed air and electrically driven diaphragm pumps can pump solids, run dry and are dry self-priming

When a membrane under performs, we find out why. Our autopsies reveal fouling, scaling, damage and underlying root causes using advanced analytical techniques. Clear, actionable reports help operators improve cleaning strategies, adjust process conditions and prevent recurring issues.

Different membranes respond differently to the same feed. We benchmark multiple commercial options side-by-side under identical conditions, providing objective data on permeability, fouling tendency, selectivity and cleanability. This helps clients make well-founded procurement and design decisions.
