Electric diaphragm pumps and pneumatic diaphragm pumps are two common industrial pumps. The following are the differences between them in terms of energy drive, operating principle and applications: 1. Energy drive and operating principle: Electric diaphragm pump:It is a diaphragm pump that uses electrical energy to drive the pump. It is mainly composed of a series of components such as motor, reducer, clutch, diaphragm pump, and sensor. The electrically driven reducer is a primary component that reduces the speed of the electric motor to a speed that can drive the diaphragm pump. Electric diaphragm pumps are powered by an electric motor, converting energy into mechanical motion to drive the diaphragm to work. Its working principle is based on the reciprocating piston principle, and is connected to the diaphragm through a motor-driven connecting rod to realize the suction and discharge of liquid. Pneumatic diaphragm pump:It is a pump that use compresse...
Pneumatic diaphragm pump is a common fluid transportation equipment, widely used in chemical, pharmaceutical, food and other industries. Correct use and maintenance can extend the service life of the Air Operated Diaphragm Pump(AODD), improve work efficiency and reduce the occurrence of failures. The following is how to use and maintain a pneumatic diaphragm pump. How to use: 1.Pre-operation inspection: Before using the pneumatic double diaphragm pump, you need to check whether the outside of the pump is damaged or blocked by foreign matter, confirm whether the connecting pipes are loose, and ensure that the working environment is well ventilated. 2. Air source preparation: Connect the appropriate air source, and set the appropriate air pressure according to the equipment specifications and requirements, usually in the range of 0.2-0.7MPa. 3. Medium preparation: Ensure that the conveying medium meets the working requirements of the pump. For medi...
Air Double Diaphragm Pump is a common industrial pump that delivers liquid through pneumatic. The characteristic of this pump is that an elastic diaphragm is set inside the pump body to separate the inlet and outlet, and the diaphragm is periodically vibrated by the action of compressed air to promote the flow of liquid. Important parts: 1.Pump body: usually made of Plastic, Aluminum alloy, SS304&SS316, TEFLON,PVDF, it has corrosion resistance and pressure resistance, and can withstand the transportation of different media. 2. Diaphragm: Located inside the pump body, it is made of elastic material( Teflon, Santoprene, Hytrel, Viton) and can be completely isolated from the liquid to prevent leakage and contamination. 3. Inlet and outlet valves: Located on both sides of the pump body, the flow direction and speed of the liquid are adjusted by controlling the opening and closing of the valves. 4. Driving device: usually a pneumatic piston, which generates v...
AODD pumps can be easily moved and require only a source of compressed air to operate. Some users choose to cart-mount pumps, allowing for even easier mobility and application versatility. A single AODD pump can be easily used for different jobs around the plant. AODD pumps do not have to be permanently affixed to a single location and do not require an electric power source. With suction/discharge hoses and an air line, you can simply place the pump on the floor and get to work. Some plants even use AODD pumps in a pinch to temporarily replace other pumping technologies while they are being repaired, as they can take much longer than AODD units to repair when taken out of service. But how do I know what type of air diaphragm pump to buy? Here are the some important considerations for choosing an AODD(Pneumatic diaphragm pump). 1.Flow rate and pressure(head): In order to select the appropriate double diaphragm pump, it’s important to understand t...
In order to select the appropriate air diaphragm pump, it’s important to understand the required flow rate in order to achieve maximum AODD pump efficiency. Diaphragm pump flow rate is the volume of fluid you can transport within a given time. Knowing the diaphragm pump flow rate will help you to determine the correct pump for your application. If you desire a higher flow rate, you’ll need a larger pump with larger port sizes. The higher the flow rate, the faster your job gets done. This ensures deadlines are met and allows increased production. When more product is produced in a shorter amount of time, profits soar. That's why it's important to purchase diaphragm pumps that require less air to operate and offer high flow rates. Today i will introduce our 1inch diaphragm pump flow rate to you. Suction& discharge size: 1inc*1inch(25mm*25mm) flange DIN/ANSI Suction lift dry : 4m Wet: 8m Max particle diameter: 4mm...
Air Diaphragm pump is driven by air, with features of simple structure, convenient disassembly and repair, stable liquid delivery, low vibration, low noise, strong self-priming ability, high viscosity of conveyed liquid, and has many advantages of self-priming pump, submersible pump, mud pump and impurity pump and other conveying machinery. The diaphragm pump uses compressed air as the power source, which can be used to pump all kinds of corrosive liquids, liquids with particles, high-viscosity, volatile, flammable, highly toxic liquids, and liquids that are not easy to flow. Diaphragm is the core component of diaphragm pump, according to different media, we have cast iron,Aluminum Alloy, PVDF, SS304, SS316 and plastic pump body for choosing. The diaphragm pump is a deceptively simple design. A diaphragm, or membrane, is positioned in a pumping chamber, usually form-fitted to achieve efficient gas or fluid movement. The membrane can be made of Teflon...
We will receive some diaphragm pump inquiries , the application is for diesel and oil. So today we want to share the Role of Diaphragm Pumps in the Oil Industry. Oil industry requires high safety standards due to the numerous risks: operators work every day with highly flammable chemicals or are faced with the threat of a well with excessive pressure that can lead to a sudden explosion. Furthermore, the plants are often located in difficult-to-access positions that make the installation and transport of equipment very complex to manage. Air-operated double-diaphragm (AODD) pumps are one of the most critical equipment to the industry. Oil workers count on AODD pumps to not only keep their production moving smoothly, but also to keep them safe. Double diaphragm pumps used in the oil industry favor the increase in plant performance and energy efficiency while optimizing the production process. Furthermore, the construction and design characteristics of diaph...
A double diaphragm pump is a positive displacement pump which utilises two flexible diaphragms that reciprocate back and forth, creating a temporary chamber, which both draws in and expels fluid through the pump. The diaphragms work as a separation wall between the air and the liquid. This pump is sometimes referred to as a membrane pump. Diaphragm pumps are self priming and are ideal for viscous liquids. Dry running is a one of the key features that differentiate Air Operated Diaphragm pumps from other types of pumps. In majority of the cases this will not damage the pump, nor its elements. This is why, AODD pumps are often used in applications in which the fluid may unexpectedly run out (sumps dewatering, tanks and cisterns transfers, etc.). However, we should be aware of the few side effects resulting from dry running of the pump and costs and risks associated with it. When running dry the Diaphragm Pump will not overheat - there are no surfa...
Diaphragm pumps are positive displacement pumps commonly used in wet commercial pumping applications. Air diaphragm pumps run on compressed air and move slurries, solvents, and other high-viscosity liquids. Selecting the right Air Diaphragm Pump for your operation involves the consideration of several key points: · Fluid Compatibility: ensure the pump materials are compatible with the fluid you intend to handle as some fluids will corrode certain pump components · Flow Rate and Pressure: determine your required flow rate (LPM: Litres Per Minute or GPM: Gallons Per Minute) and the maximum pressure (Bar or PSI) the pump needs to deliver and match that with the pump’ specifications · Suction and Discharge Ports: ensure the size and type of suction and discharge ports are aligned with piping and system requirements · Viscosity: consider the viscosity of the fluid being pumped. Diaphragm Pumps can handl...
