Pneumatic double diaphragm pumps

Pneumatic double diaphragm pumps are, just like the name says, operated by compressed air or inert gas (nitrogen) and are perfectly suited to use in a wide variety of industries as a result.

We use materials and components which defy even operating conditions which have adverse and damaging effect. At the same time, Dellmeco pumps distinguish themselves with their easy installation, high performance and long service life. Our pumps have been tested down to the last detail in order to be able to guarantee you flawless operation at all times.

Our pneumatic and electric double diaphragm pumps are available in the following materials:

Plastic double diaphragm pumps
Our modular design plastic pump housings are milled from PE, PTFE, PP or PVDF and are resistant to almost all chemicals as a result. Thanks to the smooth diaphragm surface, the pump technology allows for particularly gentle material delivery. As a result, these double diaphragm pumps are particularly robust and can be operated at temperatures from -40°C to +120°C. In addition, delivery pressures of up to 16.0 bar are possible. The oil and grease-free air motor convinces with its very low air consumption and allows for the delivery of viscose media up to a maximum of 20,000 mPas.
Metal double diaphragm pumps
Dellmeco pumps with metal housing are resistant to abrasive media. They are suitable for the delivery of chemicals, solvents, oils and paints. Alongside the gentle material delivery, we would also like to highlight the particularly low air consumption here. Our metal pumps can also be operated at temperatures from -40°C to +120°C and with delivery pressures of up to 16.0 bar. Thanks to the smooth diaphragm surface, no membrane screw is required.
Hygienic double diaphragm pumps (AISI 316L)
The hygienic double diaphragm pumps from Dellmeco are FDA approved thanks to the smooth diaphragm surface since the TFM prevents the growth of bacteria and germs. In addition, all components which come into contact with the media are made from stainless steel and thus meet the standards of the food and pharmaceutical industries. If you need special surface treatments, these are available upon request.
Solar and semiconductor models
The Dellmeco pumps in the SEMI DMS range were specially developed for the semiconductor industry. The individual assembly of the DMS pumps occurs in CLASS 100 CLEANROOMS; all parts are double cleaned and tested with demineralised water here. After completion, these are double sealed in film.
