AODD Pump Operation: A Comprehensive Guide An Air-Operated Double-Diaphragm (AODD) pump is a type of positive displacement pump driven by compressed air. Working Principle of AODD Pump AODD pumps work by using two opposing diaphragms connected to a rod. Compressed air moves the diaphragms, which creates suction and discharge cycles. Check valves control the flow of liquid into and out of the chambers. Advantages of AODD Pump AODD pumps can handle solids without clogging and are self-priming, making them suitable for lifting fluids from a lower level. They are gentle on sensitive fluids and can handle a wide range of viscosities. AODD pumps have no mechanical seal, which eliminates the risk of leakage. The flow and pressure can be easily adjusted using air pressure. AODD pumps do not require an electric motor, making them suitable for hazardous environments. Limitations of AODD Pumps AODD pumps are limited by the available air pressure. They also have pressure pulsation due ...

The Ultimate Guide to Electric Double Diaphragm Pumps Electric-operated double Diaphragm (EODD) pumps , also known as electric diaphragm pumps, are a type of positive displacement pump that uses an electric motor to drive a flexible diaphragm. Unlike pumps that rely on rotating blades, EODD pumps create suction and pressure through the reciprocating motion of the diaphragm. The two diaphragms of EODD are connected by a shaft that passes through the centre,The operation mentioned here is for AODD pump and not EODD. Please change to EODD pump working principle. An EODD pump doesn't require manual priming before operation. This type of pump creates a pressure differential that automatically draws liquid into the pump chamber. Even if air or vapour isn't fully cleared, a EODD pump can still pull fluid into the system. AN EODD pump has an electric motor whose core function is to use electrical power to produce mechanical force. The motor works on a linear mechanism, transform...

Key Differences Between PFA Lined Valves and Sleeved Plug Valves In industrial settings handling chemicals and corrosive liquids, conventional valves may not be up to the task. This is where PFA lined valves and sleeved plug valves step into the equation. Both provide corrosion resistance and dependable shutoff capabilities, each with benefits tailored to specific requirements. This article will explore the disparities between PFA lined valves, Sleeved plug valves , and aid in selecting the most suitable option for your operation. PFA lined valves: shielding against corrosion PFA lined valves, also referred to as plug valves, feature a sturdy construction that offers exceptional defence against corrosive substances. These valves are coated entirely with perfluoroalkoxy (PFA), a high-performance fluoropolymer renowned for its chemical resistance. The inert properties of PFA render it impervious to a range of chemicals, such as acids, alkalis, and strong solvents. Let's delve d...

  Tips for Choosing the Right Roll Compactor for Your Needs Roll compactors, also known as roller compactors, are machines used primarily in the pharmaceutical, nutraceutical, and chemical industries for dry granulation . A roll compactor is a machine that compacts powder into a solid mass, known as a ribbon or flakes, which can then be milled into granules. This process is essential for creating uniform particle sizes and improving the flow properties of powders. Key Components and Working Principles of Roll Compactors Roll compactors use a vertical feed screw to feed powder into the machine, where it is compressed by two counter-rotating rollers. One roller is fixed, while the other moves to control the compaction force. A hydraulic system applies the necessary force, and a control system monitors and adjusts parameters like roll speed, roll force, and roll gap. Process Parameters of Roll Compactors Roll compactors use pre-compression force to feed the material into the ...
