AODD pumps are essentially non-polluting. There are only seals between the wet area and the outside area, so leakage will only occur if one or both diaphragms fail. As part of general maintenance, diaphragms should be replaced regularly as recommended by the manufacturer. Due to the pressure relief advantage of compressed air, diaphragms in AODD pumps are used less frequently than in electric diaphragm pumps. AODD pumps are capable of handling corrosive liquids, high viscosity, sludge or sludge. Its smooth operation also makes it ideal for shear-sensitive liquids. The four internal controls usually have a ball (or cone)/slot or blade design. Ball valves provide better sealing and less wear than winged designs. Since flap valves are hinged, long-term use will eventually cause the inflection point to weaken. Ball valves wear more evenly because the ball cannot be rotated and fixed in different positions on the valve seat during operation. The advantage of the paddle check valve is that it is easier to bypass large debris entering the liquid. With no internal seals or moving parts requiring lubrication and cooling, AODD pumps can run dry continuously without damage. AODD pumps are self-priming and some have a suction power of up to 8 m. AODD pumps use compressed air rather than electricity as their power source, making them suitable for use in hazardous areas. For the same reason, AODD pumps can be safely submerged in water as long as the discharge port is above the liquid level. K-TECH FLUID CONTROLS is the manufacturer and distributor of AODD pumps.
