Double diaphragm pumps are excellent for handling all kinds of liquids. whether solids-laden, aggressive or thin and with poor lubricity. Driven by a constant supply of compressed air, this pump type can be used in explosion proof areas where highly volatile liquids and gases are present.
Pumping chemicals and abrasive fluids is always a challenge, but a double diaphragm pump is particularly well suited to such applications. The pumps have excellent properties for handling paint mixture and adding pigments, whilst varnishes and laminates can be pumped without problems. They are used extensively for pumping chemicals such as acids, solvents, resins and latex, and for the most severe applications the solid machined non-metallic diaphragm pumps are available. These diaphragm pumps are completely metal free and are made of solid machined pure PTFE and PE to ensure the highest levels of chemical resistance and leakage protection.
Containing few components means that installation is simple and mean time before failure (MTBF) is extended, thereby contributing to lower maintenance. Furthermore, being seal-less, they are leak-proof; a factor which makes them ideal for handling potentially hazardous fluids.
Without sacrificing other pump principles: the real workhorse under the pumps is the air operated diaphragm pump!
