Understanding Electrically Operated Diaphragm Pumps: Functionality and Applications Electrically Operated Double Diaphragm (EODD) pumps operate via a back-and-forth movement of two diaphragms (a flexible membrane typically made from materials like rubber, Teflon, or thermoplastic), which results in the movement of the fluid. These pumps serve several industries, including ceramics, sanitaryware, paints & dyes, metals & mining and oil & gas. They are known for their performance, reliability, ability to handle many fluid types, and superb resistance to harsh conditions. First, here is a little bit about how EODD pumps work. To explain it to a layman, an EODD pump focuses on the following mechanism: Suction stroke – Imagine a closed pump body. Now, imagine the first diaphragm moving backwards. This movement creates a vacuum, which helps draw fluid into the pump chamber through an inlet valve. Discharge stroke – Now imagine the diaphragm moving forward while putting pr...

  Key Features and Benefits of Internal Gear Pumps Internal gear pumps use two gears, one larger and the other smaller, to displace fluids via a suction and discharge cycle, especially viscous fluids such as oils, chemicals, and food and beverages. These pumps are popular among industries because of their efficiency, reliability, and ability to handle a wide range of fluids. Read on to learn about internal gear pumps' features, advantages, and significance in industrial applications. First, let's discuss their features. Positive displacement design – Internal gear pumps are designed to displace a fixed amount of fluid with each revolution. As a result, they are an excellent choice for industries that require steady, consistent fluid transfer, such as pharmaceuticals and chemical processing. Customised body - Depending on the application and the kind of fluid that needs to be displaced, an internal gear pump can be jacketed or heated (electrically) so that the fluid doe...

  Key Features and Benefits of Hydraulic Diaphragm Metering Pumps Modern industries that require precise fluid dosing, including chemical processing, water treatment, and food production, often need an efficient, high-performance, and reliable metering pump that delivers again and again. Hydraulic diaphragm pumps have been known to meet such stringent requirements and more. These systems feature a special kind of pump that transfers fluids by means of a diaphragm mechanism. These pumps work almost like regular pumps with a rotary motion; however, they use hydraulic pressure to drive the circular movement of a movable diaphragm. In this article, you will learn about the key features and benefits of hydraulic diaphragm metering pumps and understand their role in improving industrial efficiency and operational safety in the context of modern industry applications. So, how do hydraulic diaphragm metering pumps work? The simple answer lies in three words - hydraulic actuation mecha...

Comprehensive Guide to PFA Lined Pump Specifications and Benefits For industries handling corrosive, high-purity, or hazardous chemicals, a run-off-the-mill pump would barely work. These industries need pumps that offer superior chemical resistance and can handle all sorts of aggressive fluids. PFA (Perfluoroalkoxy) lined pumps provide the mechanical strength of metallic casings with the superior chemical resistance of PFA lining, making them perfect for displacing the most challenging fluids. So, how does a PFA lining make a pump better?  PFA is inert to almost all aggressive chemicals, including strong acids, bases, solvents, and oxidisers. Typical metal pumps can be easily corroded over time with repeated fluid contact. The PFA lining acts as a non-reactive barrier, a protective layer of sorts, between the pump's metallic body and the fluid, maintaining structural integrity even in highly corrosive environments. The PFA lining is mechanically locked into the metal armour, off...

  Air Operated Double Diaphragm Pumps: Efficient, Reliable, and Cost-Effective Solutions A type of positive displacement pump, the Air-Operated Double-Diaphragm (AODD) pump , has two chambers that are filled and discharged via diaphragms.  AODD pumps, thanks to their versatility, are a popular choice among industries such as pharmaceuticals, chemicals, food and beverage, mining, and wastewater treatment. They are capable of handling different kinds of fluids, from aggressive chemicals to purest liquids and really viscous slurries. AODD pumps are air-operated, which means they use compressed air as their source of power. So, in an AODD pump, there are two diaphragms connected by a shaft, which move back and forth within a chamber. It all starts when compressed air enters and moves the diaphragm inside the pump chamber. When one diaphragm is pushed outward, a vacuum is created in the chamber, which pulls the liquid via the inlet. While all this happens, the other diaphragm is ...

Advanced Chemical Process Pump Solutions In several modern industries, including pharmaceuticals, chemical processing, oil & gas, food processing and wastewater management, pumps play an important role when handling corrosive, abrasive, and hazardous fluids. These pumps do not merely move liquids from one place to another; they effectively handle arduous operating conditions, offering industries a durable and reliable solution for their needs. Here are some key types of advanced chemical processing pumps: Centrifugal Pumps : As the name suggests, centrifugal pumps work on the basis of a circular movement; the pump displaces fluids via rotational energy from an impeller. One of the most commonly used pumps today, centrifugal pumps are known for their efficiency, simplicity, and ability to handle large flow rates. As far as their working mechanism is concerned, the fluid enters the pump through the inlet or the suction side, after which, the rotating impeller creates a centrifuga...
