Complete buying guide for the diaphragm pump

A diaphragm pump also called a membrane pump, Pneumatic Diaphragm Pump, Air Operated Double Diaphragm Pump is the positive displacement pump. It is used in combination with the reciprocating and action of a rubber, Teflon or thermoplastic diaphragm and suitable valves either side of the pump. This helps in checking the value, flap valves, butterfly valves or any other form of shut-off valves to the fluid of the pump.

Types of diaphragm pumps:

• The one in which the diaphragm is sealed at one side and the other side offers fluid to be pumped and the other for the air or hydraulic fluid. The pump is flexed and causing the volume of the pump chamber to increase or decrease. A pair of non-return check valves will be present that helps in reverse the flow of the fluid in the pump.
• Those employing single or multiple unsealed diaphragms with the fluid to be pumped on both sides. These pumps will be flexed and cause a change in volume.
• Those pumps that involve in the volumetric positive displacement and the prime mover of the diaphragm will be electro-mechanical that that works through the crank or geared motor drive or they might purely be mechanical like the handle or lever.

Things to consider when you are choosing the pump:

There are certain things that you need to make note of when you are buying the pump from the diaphragm pump manufacturers.

• Fluid: The makeup of your process fluid is very important to the choice of the pump. Make sure if there is a need for chemical or the corrosive requirements and about the particles present in it.
• Viscosity: It is also necessary to know the viscosity of the liquid and it is highly important for the robust pumps to move.
• Flow rate: You should be concerned regarding the flow of the liquid. More viscous fluid requires more robust pumps.
• Temperature: The choice of the pump needs to depend on the temperature of the liquid that is pumped in.
• Pressure: It is one of the major factors and one that is intertwined with the flow rate. Also, this plays a vital role in choosing an appropriate pump. With the help of a pump curve graph, it is possible to determine the relationship between flow and pressure.

Working of the diaphragm pump:

Though there are so many benefits that are offered by the Diaphragm pump and how easy it is for anyone to use even without the technical training. Here is the quick review of the pump and its working.

The compressed air line in the pump will be operated by moving the two diaphragms side to side simultaneously. One side diaphragm creates suction to gain some amount of fluid through the outlet port form the other side. You can find two ball valves on either side of the pump, operating together. Here, when one of the valves is closed, the other will get opened automatically.

This is the basic working of the pump and with this basic understanding of the working of the pump, it easy to operate the pump. Due to the positive nature of the AODD Pump, it is extremely versatile. When you need the perfect pump, you need to consider certain features based on your needs and job.

Final thoughts: You can initially make a note on the needs of the pump and compare the technical details of them with necessary values. This can help you highly with the best selection of the pumps and the way of operations. Also, you should be appropriate in choosing the vendor so that he will help you in fixing any repairs and services as well.
