All about diaphragm pumps

Diaphragm pumps, also known as air-operated diaphragm pumps (AODD pump), are positive displacement pumps that operate using compressed air to compress and expand the diaphragm, creating a suction and discharge action that moves fluids. These pumps are ideal for handling viscous or abrasive fluids, including oils, chemicals, and sludge. They are also versatile and can be used in various industries, such as chemical processing, food and beverage, mining, and wastewater treatment.

We offer a wide selection of diaphragm pumps from trusted brands such as ARO. Our team of experts is available to assist with diaphragm pump operation and maintenance, ensuring that your pumps operate efficiently and reliably for years to come. Contact us today to learn more about our AODD offerings and how we can assist you with your pumping requirements.

The design of the diaphragm pump

Air operated diaphragm pumps are positive displacement pumps that use a flexible diaphragm to move fluids. They are designed to handle a range of fluids, from thin and viscous liquids to slurries and solids, and can be used in various industries. Their compact and lightweight design makes them ideal for applications where space is limited.

Air operated diaphragm pumps – uses, benefits and applications

Diaphragm pumps are versatile fluid transfer devices that are used in a wide variety of applications. One popular type of diaphragm pump is the ARO air-operated double diaphragm pump from Liquid Movers. These pumps are designed for general fluid transfer and can reliably transfer fluids with a range of viscosities. In addition, they pump large particles without causing any damage. Here are some of the uses and benefits of diaphragm pumps:

  • Handling corrosive and abrasive fluids
  • Ideal for use in potentially explosive areas
  • Customisable
  • Cost-effective
  • Can transfer a wide range of fluids and liquids

Frequently Asked Questions

A diaphragm pump operates by using a flexible diaphragm to displace fluid. As the diaphragm moves back and forth, it creates a vacuum on one side and pressure on the other, which forces fluid through the pump.

Diaphragm pumps are versatile pumps that can handle a variety of fluids, but the specific fluid that is appropriate for a diaphragm pump depends on the pump, components, and materials of construction that will come into contact with the fluid.

Important maintenance factors for diaphragm pumps include regular cleaning, inspection of the diaphragm and valves, lubrication, checking fasteners and connections, monitoring performance, and replacing worn components.

Diaphragm pumps are used in a wide range of industries, including chemical processing, petrochemical, pharmaceuticals, food and beverage production, mining, agriculture, water treatment, and wastewater treatment. They are also used in applications where high viscosity or abrasive fluids need to be pumped, such as slurries or paints. Additionally, diaphragm pumps are popular in the oil and gas industry due to their ability to handle high pressures and corrosive fluids.
