Progressive cavity pumps are capable of transferring fluid through the cavities embedded in them. The cavities that are present in these machines are fixed having similar shape throughout. The uniqueness of these pumps is that they have numerous cavities present in them and the fluid is driven through these cavities. The movement of the fluid in these pumps follows a process known as positive displacement. The cavities rotate along with the rotation of the rotor simultaneously. The fluid moves in this pattern through the motor and the flow depends directly on the rate of rotation of the rotor. With the receding of the cavities at the end, they overlap with the other parts of the pump. These pumps are ideal for moving fluids that are highly viscous and sensitive in nature. Most industries make use of these machines for smooth flow of liquids of this nature that can be hazardous at times.


The progressive cavity pumps have a helical rotor that is fitted in them for effective and easy fluid displacement. Apart from the helical rotor, couple of helixes is also connected to these machines for efficiency. These ... href="http://www.globalpumps.com.au/products/pumps/helical-rotor-pumps/">helical rotor pumps have a rubber stator tightly fitted to the rotor especially when it is rotating. The helical rotor’s wavelength is twice that of the helical hole that is present inside the rubber stator. The cavity formation in the helical rotor pumps is mainly responsible for the sitting arrangement of the stator and the rotor. The fluid transfer takes place through these cavities.


If there is high pressure during fluid flow in the pump, then there is a high possibility of the fluid leaking out of the cavity seals. It is extremely crucial that you maintain the pressure of the fluid flow at all times while working with peristaltic pumps otherwise leakages can occur during fluid movement. Drilling of wells is done with the help of these machines. Thus, progressive cavity pumps help in carrying out the major portion of the applications that are an integral part of well drilling. Longer pumps can be used in tasks where there is high pressure in the fluids. These motors can do the job perfectly without any hiccup as such. Pumps like these have been specifically manufactured to do these types of job seamlessly. In industries of today, generally you will come across motors having 2 to 12 cavities that are used for carrying out day to day services. Slurry pumps that are normally used in other industries are made up of steel having hard and smooth chromium surfaces.


There are also machines that are known as drum pumps. The name of this motor suggests that it is generally used in barrels and drums. These pumps are available in wide array of shapes and sizes in the market. Some of the commonly used variants have air, double diaphragms, piston, lever and others. The choice of the machine depends on the size of the container or vessel where it will be put to use. For different types of barrels there are different kinds of pumps that can be used. The drum pumps are mainly used in 55 gallon barrels. It is the barrel containers that are the real containers having integrated pump systems to take care of the task. These are extremely light in terms of weight and absolutely safe to use. If you happen to buy these drum pumps then you will get a whole range of accessories like the dispensing nozzles or the flow-meters.


Mag drive pumps or the centrifugal pumps have impellers that rotate at high speeds and the vanes remain fixed to the pumps. The flow of the liquid from one end to the other happens with the help of impellers. These are quite reasonably priced and are completely safe and easy to use.
