Dellmeco DME Metal Diaphragm Pump<\/strong> is an electro-mechanical double diaphragm pump with a housing made of aluminium, PTFE-coated aluminium, cast iron or AISI 316 stainless steel. The series is designed for industrial transfer of slurries, suspensions, paints and viscous products. The manufacturer is the Polish company Dellmeco. Steiner Ukraine is the official Dellmeco distributor in Ukraine.<\/p>\n

The housing material is selected by compatibility with the product: AISI 316 if the process requires stainless steel, otherwise aluminium or cast iron. Pump weight depends on the material and is given in the table below. With NBR or EPDM diaphragms, the aluminium pump operates up to 70 \u00b0C, briefly up to 80 \u00b0C; with TFM\/PTFE diaphragms, up to 110 \u00b0C, briefly up to 120 \u00b0C.<\/p>\n

Dry suction lift ranges from 3 m (DME 20) to 5 m (DME 50 and 80); wet suction lift is 8 m. Diaphragms: NBR, EPDM, TFM or TFM\/PFA; valve balls: NBR, EPDM, PTFE, and for DME 20\u201350 also AISI 316 or polyurethane.<\/p>\n

How does DME differ from an air-operated diaphragm pump?<\/h2>\n

DME diaphragms are driven by an electric motor through a crank, not by compressed air. No compressor or air network is needed. The diaphragm stroke is constant, so the flow is almost independent of pressure and viscosity. Flow is controlled by a frequency inverter within 70\u2013140% of the rated value.<\/p>\n

Where is the Dellmeco DME Metal diaphragm pump used?<\/h2>\n

The manufacturer lists metallurgy, mining and ceramics, production of pigments, paints, resins and coatings, the automotive and paper industries, stone processing, shipbuilding, water supply and wastewater treatment. Pumps for wastewater and slurries are covered in the article \u201cProblems in wastewater treatment: causes and effective solutions\u201d<\/a>.<\/p>\n
