Lutz series PURE Stainless steel 34 Through thick and thin: Lutz Double Diaphragm Pumps The new series of Lutz double diaphragm pumps combines the characteristics of the previous model with new technical features. They convince with high-quality materials and the latest available technology. The application possibilities of the double diaphragm pump in sizes 1/4" to 2" are very versatile: From the automotive industry and the waste water sector, to the decanting of chemicals such as acids, alkalis, alcohols and solvents, to the feeding of large-scale plants. But the pumps also reliably solve...

4 Double diaphragm pumps Lutz double diaphragm pumps are used in almost all branches of industry. Since the applications are becoming more and more versatile and demanding, the user can choose from a variety of material, such as high-quality thermoplastics or different metallic variants. The pumps made of glass fibre reinforced polypropylene (PP) and carbon fibre reinforced polyvinylidene fluoride (PVDF) impress with their high mechanical strength and maximum resistance to aggressive and concentrated acids and alkalis. In addition to some versions made of plastic all metallic pumps are also...

Installation capabilities Mobile installation Hanging Flooded suction Submerged operation (AODD 1 1/2” and 2” only

Lutz Double Diaphragm Pumps are designed for a variety of industrial applications. Stationary or mobile installation The pumps can be mounted either in a stationary position or, depending on requirements, transported mobile to different places of application to empty the liquids from different containers. Flooded suction If the liquid level is above the suction inlet, it is called positive inlet. If the maximum inlet pressure is exceeded, the suction line should have appropriate shut-off valves. Self-priming When the suction is below the level of the liquid, the pump has to prime the...

Functions The Lutz double diaphragm pumps operate volumetrically and belong to the category of oscillating displacement pumps. The suction and pressure cycle occur simultaneously in alternating phases. The operating principle depends on the volume change of two chambers. As shown in the scheme below, a positive volume change takes place in one chamber, while a volume decrease occurs in the second chamber. This leads to priming resp. displacement of the pumped liquid. In detail: The overpressure created in the chamber (A) closes the suction valve and opens the pressure valve so that the...

Special features Optimised air control valve Increases the efficiency of the pump and reduces the air consumption (depending on the operating point). Flow-optimised hydraulic system Enables higher flow rates due to lower, internal pressure losses. Elastomer diaphragms Use of rubber compounds with embedded nylon fabric to increase mechanical strength. The most common elastomers are based on nitrile butadiene rubber (NBR) TFM membrane Modified PTFE that is refined in its molecular structure and thus offers improved characteristics regarding safety and reliability. In Lutz double diaphragm...
