Non-Metlic Air Operated Double Diaphargm Pump PVDF air operated double diaphragm pumps can transport high viscosity fluids such as paint, sludge and sewage, but the flow rate and pressure depend on the actual application. If you have any questions about compatibility with high viscosity fluids, please call our application experts for more information. 鈼?PVDF air operated double diaphragm pump can deliver fluids with viscosity up to 11,000 cp. 鈼?Air motor eliminates sparking problems associated with electric pumps. 鈼?Bolted pump design provides easy access to the pump head for maintenance and maintains a seal after repeated repairs. 鈼?This product is also suitable for low abrasive portable fluids, suspended solids. 鈼?Safe Handling鈥擣or high viscosity and shear sensitive materials. 鈼?The encapsulated muffler provides excellent noise reduction. Operating principle Two diaphragms connected by a diaphragm rod work together to create fluid motion in the pump. One side is in suction mode and the other side is in discharge mode. The inward movement of the diaphragm creates suction that brings the balls closer together. When this happens, the top valve closes and the bottom valve opens, which allows fluid to enter the chamber through the bottom port. The outward movement of the diaphragm induces a discharge motion that causes the spheres to move away from each other. At this point, the top valve is open and the bottom valve is closed. This allows fluid to flow out of the chamber and out through the top port. The process alternates between the two chambers in a continuous cycle. The pump diaphragm is driven by compressed air, and the movement of the main air valve drives the compressed air to move left and right. Material Material Profile:Operating Temperatures: Max.Min. CONDUCTIVE ACETAL: It brings good impact resistance, ductility, abrasion resistance. It is generally inert and has good chemical resistance except for strong acids and oxidizing agents.190掳F 88掳C-20掳F -29掳C EPDM: Exhibits very good water and chemical resistance. Poor tolerance to oils and solvents, but moderate tolerance to ketones and alcohols.280掳F 138掳C-40掳F -40掳C FKM (FLUOROCARBON): Good resistance to various oils and solvents; especially all aliphatic, halogenated hydrocarbons, acids. Hot water or hot water solutions (above 70掳F (21掳C)) will corrode FKM.350掳F 177掳C-40掳F -40掳C HYTREL庐: Good on acids, bases, amines and glycols at room temperatures only.220掳F 104掳C-20掳F -29掳C NEOPRENE: All purpose. Resistance to vegetable oils. Generally not affected by moderate chemicals, fats, greases and many oils and solvents. Generally attacked by strong oxidizing acids, ketones, esters and nitro hydrocarbons and chlorinated aromatic hydrocarbons.200掳F 93掳C-10掳F -23掳C NITRILE: All-purpose. Generally unaffected by medium chemicals, fats, greases and other oils and solvents. Typically attacked by strong oxidizing acids, ketones, esters and nitro and chlorinated aromatic hydrocarbons.190掳F 88掳C-10掳F -23掳C NYLON: It has high strength and toughness over a wide temperature range. It has moderate to good resistance to fuels, oils and chemicals.180掳F 82掳C32掳F 0掳C POLYPROPYLENE: A thermoplastic polymer. It has moderate tensile and flexural strength and is resistant to strong acids and bases, but is attacked by chlorine gas, fuming nitric acid and other strong oxidizing agents.180掳F 82掳C32掳F 0掳C PVDF: (Polyvinylidene Fluoride) A durable fluoroplastic with excellent chemical resistance. It is ideal for UV applications with high tensile strength and impact resistance.250掳F 121掳C0掳F -18掳C SANTOPRENE庐: Injection-molded thermoplastic elastomer without a fabric layer. It has a long mechanical flex life and excellent wear resistance.275掳F 135掳C-40掳F -40掳C UHMW PE: A thermoplastic that is highly resistant to a wide range of chemicals, it has excellent abrasion and impact resistance, and resistance to environmental stress cracking.180掳F 82掳C-35掳F -37掳C URETHANE: It has good abrasion resistance but poor resistance to most solvents and oils.150掳F 66掳C32掳F 0掳C VIRGIN PTFE: (PFA/TFE) Chemically inert and practically impermeable to water. Few chemicals are known to react chemically with PTFE; molten alkali metals, turbulent liquid or gaseous fluorine, and some fluorides such as chlorine trifluoride or oxygen difluoride, which readily release free fluorine at high temperatures.220掳F 104掳C-35掳F -37掳C The maximum and minimum temperatures are the limits at which these materials can operate, and the combination of temperature and pressure can affect the life of diaphragm pump components. Maximum lifetime should not be expected at the extreme limits of the temperature range.Non-Metlic Air Operated Double Diaphargm Pump website:
