The Top Three Uses of Diaphragm Pumps



A quick explanation of what a diaphragm pump is (sometimes also referred to as a membrane pump), will help you to understand their most useful applications. To put it quite simply, a diaphragm pump is one that uses positive displacement by utilizing a pliable membrane, often constructed of some sort of flexible material similar to rubber, thermoplastic or Teflon to pump fluids through a vacuum process that causes a series of valves to open and close, allowing the material that is being pumped through to enter the intake end of the pump and force it through the body exiting the opposite end of the pump via another valve.

This style of pump incorporates a series of check valves ensuring that the flow of liquid can not reverse its direction of travel through the pump's housing. The pressure inside of the pumps chamber, causes this diaphragm to expand and contract, causing the vacuum, which obviously is the critical function of any type of a vacuum pump. Various models of these pumps operate by means of electrical or mechanical power. For this reason, it is vitally important that you choose the proper diaphragm pump for your application. You obviously wouldn't want an electrically operated pump for a task that requires the pump to be submerged in liquid.

Diaphragm pumps do not contain any friction causing internal parts that make contact with each other, making them highly reliable and far less susceptible to wear, making them not only far more efficient, but also much longer lasting. These characteristics also drastically reduce any possibility of clogging up when solids enter the actual pump housing, also greatly reducing the likelihood of a malfunction, such as is common with vain pumps. Do to the fact that using a good diaphragm pump offers many advantages in certain applications. For instance, some versions of these pumps are well designed to move mud or sludge over considerable distances. This makes diaphragm pumps ideal for pumping out septic tanks, or any other application where pumping out semi-solid materials can cause problems, or even them malfunction of different types of pumps.

Other applications where a diaphragm pump will excel in comparison to their counterparts, is in the use of pumping a wide variety of materials, including highly abrasive and corrosive media such as; concrete or grout, coolant chemicals, acids, combustible materials, effluents, diesel fuel, gasoline, ground water and chemicals. There are yet others that can handle the delivery of hazardous chemicals like, liquids and solids, liquids containing oils even highly viscous fluids.

Besides the many industrial uses for these types of very efficient pumps. They can also quite commonly be fond in many average households around the world. This type of diaphragm pump is usually more commonly referred to as a fish tank pump.

The most common uses for these types of pumps are, as previously mentioned, are in fish tanks due to the diaphragm pump having a very high level of efficiency. This is a commonly sought after quality in a fish tank pump, due to their frequency of use. Also, they are very dependable and long lasting pumps, which is a very good quality in an appliance that you will very seldom be shutting off.

Another common use for this type of pump is in the water reclamation industry, due to the fact that this pump can quite easily move solids without issue of malfunction or clogging.

These pumps operate without having to physically contact the material being pumped, they are useful tools in the food production industry as well.
