Dellmeco pumps can be used for the delivery of powders up to a bulk density of 800 kg/m3.
Thanks to the continuous blowing of compressed air into the diaphragm chambers, depositing of the powder is prevented. Shearing of the diaphragms while the pump is starting up owing to the powder residue found in the diaphragm chamber is thus prevented.
Dellmeco powder pumps are available in metal designs in all nominal sizes. The pumps are therefore predominantly suitable for the delivery of ground limestone, talc, coal dust, soot, quartz dust or silicone. This variant of the double diaphragm pump is even used in the food and pharmaceuticals industries. Among other things, it can be used to deliver sugar and cocoa powder, or even ground rubber or silicon oxide – as well as a wide variety of pharmaceutical base materials.
