7 Applications Of Diaphragm Pumps

12th April 2023

Behind all the impressive technology in the medical, chemical, agricultural, and many industries, one component offers an essential contribution—a diaphragm pump.

Diaphragm pumps are air-driven positive displacement pumps that use a flexible membrane and pistons to create suction and pressure. This innovative equipment is becoming increasingly popular in various applications owing to its reliable performance and low maintenance requirements. In fact, experts anticipated the global diaphragm pumps to reach USD$8,867 million by 2032 at a yearly growth rate of 6.2% during the analysis period. This figure shows the growing demand for this mechanical device.

KNF, among other leading diaphragm pump providers, offers a wide selection of customisable solutions, so you’re sure to find a product that meets your needs. But before purchasing, here are seven applications of diaphragm pumps in different industries.

  1. Food And Beverage Processing

Maintaining high cleanliness and quality control standards in the food and beverage industry is a top priority. After all, any mishaps can have severe consequences for a company’s reputation and customers.

Diaphragm pumps eliminate any risk of product contamination due to their self-priming and dry-running capabilities. These pumps are also well-suited for transferring hazardous chemicals, as they don’t require lubrication or a drive shaft.

  1. Medical And Pharmaceutical Production Lines

It’s no secret that the medical and pharmaceutical industries must adhere to strict regulations regarding product quality. This is especially true in diagnostic, laboratory, and research settings.

Thanks to their reliable performance and superior quality, diaphragm pumps have become the go-to tool for drug and medical device manufacturing. They can be used for liquid transfer, filling, dosing, and dispensing applications. Medical practitioners, researchers, and chemists can rely on diaphragm pumps to safely and accurately handle their samples.

  1. Wastewater Treatment Plants

It’s no secret that wastewater contains a variety of pollutants, including faecal matter, oils, and suspended solids. These substances can be hazardous to the environment and human health if not properly controlled. That’s why water treatment methodologies are necessary.

Diaphragm pumps are excellent for this job as they can effectively evacuate wastewater with non-toxic and frictionless pumping. Their ability to handle thick and viscous liquids while keeping the noise levels low makes them an ideal choice in wastewater management.

  1. Chemical Manufacturing Processes

Producing chemicals is a delicate process and requires specialised equipment to meet safety protocols. It involves various tasks such as mixing, transporting, and sampling substances. If any of these activities are executed incorrectly, the chances for incidents can increase significantly. A diaphragm pump can minimise the risk of such occurrences by ensuring an accurate and secure process.

Diaphragm pumps are designed to handle highly corrosive and toxic components efficiently. They are the best option for transferring corrosive and toxic liquids, as they don’t require any contact between their rotating parts and the chemicals. In addition, they can work with different fluids without having to shut down or empty the pump.

  1. Mining Operations

You may think that diaphragm pumps wouldn’t suit a rugged and hostile environment like the mining industry. However, they have become an invaluable tool for this sector because of their robustness and durability.

The pumps help to evacuate water, slurry, or other liquids from underground mining sites. This can reduce the chances of flooding and other risks associated with this type of operation.

  1. Painting And Coating Spraying

The automotive, construction, and other industries depend on accurate and precise painting and coating spraying operations. This is particularly true for projects that involve large-scale surfaces, as any inconsistency or mistake can result in a costly rework.

Diaphragm pumps are employed for this purpose as they can robustly handle paints, resins, and other liquids with high concentrations of solvents and other additives. They provide a continuous, non-turbulent flow without needing external lubrication. In other words, they can ensure a consistent and reliable finish in any painting or coating application.

  1. 3D Printing Procedures

Did you know that diaphragm pumps are also used for three-dimensional (3D) printing? This process requires the use of multiple liquids to build a 3D object with layers of materials.

Diaphragm pumps can handle the accurate delivery of a wide range of resins and other elements used in 3D printing without shutting down or emptying the pump. That is, the device can perform without interruption, increasing productivity. This feature makes diaphragm pumps ideal for applications requiring precise and repeatable results.

Takeaway

No matter what industry you’re in, diaphragm pumps can be a reliable tool for many of your operations. Their abilities to accurately and precisely handle corrosive, abrasive, and hazardous liquids make them a popular choice for many applications. Invest in the right diaphragm pump for your needs, and you can reap the benefits of excellent work performance, safety, and efficiency.
