Diaphragms on Air Operated Double Diaphragm Pumps A double diaphragm pump is also called a positive displacement pump which utilizes two flexible diaphragms, connected by a shaft,which move back and forth. The diaphragms work as separation of the air one side and the medium on the opposite side of the diaphragm. The diaphragms, in most common AODD pump designs, maintain a seal at two points: 1. At the center diaphragm hole by tightening the inner and outer diaphragm plates to the main shaft, capturing the diaphragm. 2. A seal also occurs at the outer circumference of the diaphragms, usually at the molded-in sealing bead or from sealing grooves on the inner air chamber and/or outer fluid chamber. The seal occurs from the compression created when the outer chamber bolts (bolted pumps) or the large clamp band assemblies (clamp style pumps) are tightened.
Diaphragms Maintenance is key As part of a general maintenance program, diaphragms should be replaced regularly, according to the manufacturer’s recommendations. The efficiency, lifetime and stability of a diaphragm in an AODD pump is dependent on its compressed air supply. The compressed air supply must be at the same or a higher pressure than the fluid to be pumped, with a maximum of 0.3bar (4.35PSI) in difference. This tends to limit the use of AODD pumps to only low pressure applications. Diaphragm pumps will move nearly any kind of fluid in multiple industries like: * Aerospace* Automotive* Constructions* Ceramics* Chemical* Coating & Glue* Semi-Conductor* Cosmetics* Energy * Environmental* Food & Beverage * Transportation*Mining*Oil & Gas*Packaging*Pharmaceutical* Printing & Painting * Pulp & Paper*Sanitary Steel & Metal
Every industry or solution has it own selection requirements if it comes to diaphragm material. They come in a variety of materials (availability may vary per manufacturer) and designs to meet specific application needs such as chemical compatibility,temperature, abrasion resistance, and certification requirements. Most common used materials supplied by Zhengyuan Machinery Pump Parts: Neoprene: An excellent general purpose diaphragm for use in non-aggressive applications such as water-based slurries, well water or sea water. Exhibits excellent flex life and low cost. Color Code: Green (common color) Different OEM intent to use brand specific color Buna-N/Nitrile: Excellent for applications involving petroleum/oil-based fluids such as leaded gasolines, fuel oils, non-synthetic hydraulic oils,kerosene, turpentines and motor oils. Color Code: Red (common color) Different OEM intent to use brand specific color FKM/Viton: Excellent for use in applications requiring extremely hot temperatures. May also be used with aggressive fluids such as aromatic or chlorinated hydrocarbons and highly aggressive acids. PTFE would normally be used with these aggressive fluids as its flex life is better than Viton®. However, in applications involving suction lift outside the range of PTFE, Viton® will be the preferred choice for highly aggressive fluids Color Code: Silver or White (common color) Different OEM intent to use brand specific color Santoprene: Excellent choice as a low cost alternative to PTFE in many acidic and caustic applications such as sodium hydroxide, sulfuric or hydrochloric acids. Exhibits excellent abrasion resistance and durability at a cost comparable to neoprene Color Code: Cream (common color) Different OEM intent to use brand specific color Hytrel: Exhibits excellent abrasion resistance, flex life and durability. This material is FDA approved for food processing applications. An outstanding general purpose diaphragm as well. Color Code: Cream (common color) Some brand use alternative color PTFE: Excellent choice when pumping highly aggressive fluids such as aromatic or chlorinated hydrocarbons, acids, caustics, ketones and acetates. Exhibits good flex life compared to a standard rubber diaphragm Color Code: white. (Compound diaphragms: light blue)
