Man and machine is greatest pal right from the dawn of the ancient civilisations. Mankind’s insatiable quest to hear the unheard, see the unseen and know the unknown actually drove him throughout the different ages. In this endeavour his only intention was to find such a machine or tool or thing which can help him in his daily quest.In this way only all of the ancient discoveries like the fire, water, agricultural processes had happened to make this place a better habitable one. Also, careful observation as well as rationale thinking has contributed largely in his thousand years old journey. In this quest for finding out the exact logic behind each and every happening around him actually made his mind a bit scientific one. Hence, he started to think in more logical way which made him intelligent and with power of intelligence, his thought process also improved manifold. As a result, we, the modern Homo sapiens developed as the most advanced living creatures on the face of earth.


Now, just for a second, think of electricity. They practically run our modern cities, towns, municipalities etc. and without them ...
... the whole civilisation would get paralysed. Starting from television, fridge, music system, mixer-grinder, computer, laptop, microwave ovens, grillers, toasters you name any of the utility devices used in our daily lives and they get run by electricity.So, if electricity goes out just for half of an hour, we start to think how we are going to perform the same tasks without using the advanced devices. The idea did not occur to us that before the discoveries of these devices, human used to perform these tasks on their own and they were being invented to achieve the same goal in lesser time and with greater quality. Pumps are also such kinds of utility devices which get used in any sector around us starting from agriculture to automobile, ranging from domestic to mining sector.Mainly, intended for the movement of liquids of diverse nature (some may be highly viscous, some other may be chemically reactive, abrasive, toxic and some other can be flammable etc.) and some of the times can be mixture of liquid with gas or liquid having very high solid contents between places or containers.
For the food and beverage sector, mainly for the dewatering or sludge applications, highly advanced helical rotor pump also known as progressive cavity pumps are being used as it can transfer fluids progressively using small, sharp, cavities with the turn of rotor. They have rotors made of metals and being placed under stators which are elastic in nature and made of natural rubber, EPDM, nitrile or Viton etc.Mainly specified liquids which are heterogeneous, frothing, viscous, abrasive, shear-sensitive in nature are being carried by the machine. In addition, they have user friendly design and self-priming abilities and enjoy valve-less operation.


For the food and beverage industry, different types of food grade pumps are used like:-

a. Air operated diaphragm

b. Helical rotor

c. Drum/ barrel/ container

d. Centrifugal

e. Lobe

f. Metering/ dosing

g. Undersink chambers

h. Peristaltic hose etc.


For corrosive chemically hazardous aggressive, dirty fluids, advanced mag drive pumps are being used across the globe.
