For liquids which have to be mixed before processing and then pumped or which contain small solids, the new DMP mixing system with an integrated air-operated double diaphragm pump has been developed by Lutz. The mixing and pumping process is performed via a suction and mixing tube and a 3-way cock. The pre-assembled system is immediately ready for operation with a few simple steps and is also suitable for explosive liquids. A compressed air driven double diaphragm pump in the size ½" made of stainless steel (1.4404), which is mounted on a base plate, serves as the delivery unit. With the universal chemical hose used, a variety of liquids can be pumped. For example, paints and varnishes, emulsions, dispersions, suspensions, water/oil mixtures, liquids with increased viscosity and solids content. The delivery rate is 57 l/min., the maximum operating pressure is 8.2 bar and the maximum temperature of the fluid is 93 °C. Solids up to a diameter of 3.2 mm can be pumped. The total weight of the system (including pump) is 21 kg.
