You may be going into the food manufacturing business soon and thus you will need to know some of the needed equipment needed in such a business. And in your proposed venture you may have come across the term positive displacement sanitary pump. Read on in this article to find out what kind of equipment this is and how it works and is essential for your food production needs.
Basically a pump is used to move solutions, food products, and slurries that will be processed according to set standards of cleanliness and hygiene. These standards are either set by the private corporation or even by law. In the continental United States, the Food and Drug Administration with the US Department of Agriculture set these same standards.
There are basically two types of pumps used in the food processing and manufacturing industry, being the centrifugal type and the positive displacement type. The former uses centrifugal force to push liquids and such while the latter makes use of rotating lobes in fixed chambers, which when active creates suction for the liquid to flow through. Both though different, are alike in the way that they are manufactured to eliminate the growth of bacteria in the process.
Positive displacement pumps are sometimes called PD pumps and are fast gaining in popularity when talking about special applications involving thick liquids or liquids with fragile solid materials. Although they cannot produce a high flow rate like centrifugal pumps, they can produce much greater pressure.
These pumps rely on pressure to move liquids through to a discharge system. The pressure is slowly built up by rotating lobes or parts pushing liquid into an enclosed and vacuum sealed chamber. The release velocity of this liquid is much slower than a centrifugal setup and thus ideal for liquids that have some form of fragile solids mixed in.
Two types of PD pumps are currently in use in the food industry today. These are the rotary type and the reciprocating type. The former type of pump makes use of rotating parts to move liquid through. This is most useful for applications involving liquids with some form of fragile solids mixed in. Those applications needing an elimination of reverse flow processes are best serviced by the use of reciprocating type, which also has valves to create and eliminate vacuum pressure apart from moving lobes.
The sole advantage of the PD type of mechanism is that it can provide a constant flow of liquid within the range of medium to high pressure applications. This is particularly important in breweries and dairy production facilities which deal a lot with viscous liquids. Other viscous fluid applications best serviced by PD type mechanisms are found in firms that produces vegetable oils, molasses and such.
Thus this short article has provided a primer for you regarding this kind of pump that is widely used in the food manufacturing and processing sector. This article is in no means exhaustive but it is hoped that it has contained enough information to enlighten the uninitiated in the ways of pumps and pump process as used in food processing.
