Some of us will be thinking of going into the food manufacturing business and in view of this will need to be familiar with some of the industry terms and equipment used. In all likelihood, you may have come across the term positive displacement sanitary pump. This article will introduce you to what this piece of equipment is all about and why it is essential or used in some food manufacturing processes.
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.
Food processing sanitary pumps come in two types. One is a centrifugal type pump, which uses centrifugal force to pump fluids or mush right along, and the other is a positive displacement pump. The latter makes uses suction via rotating lobes in different fixed chambers. Either way, both are designed to prevent bacterial growth in the process.
PD pumps, the acronym for positive displacement types of mechanisms, produce much higher flow pressures than centrifuge mechanisms, although the latter gives much higher flow volume. Thus the PD pump is much sought after for specialist applications which involve thick liquids or liquids with fragile solids.
As these kinds of mechanisms rely on rotating parts or lobes to create pressure based on volume, it produces less velocity when liquids are ejected into a discharge system. This is thus much more useful and needed when dealing with liquids that have some form of inert fragile solids within them.
As such there are two types of PD pumps. One is the rotary type which uses rotating parts only to move liquids. This is most useful for liquids that have some solids in them. The other type of PD pump is the reciprocating pump, which also makes use of vacuum pressure for applications that require the elimination of reverse flow. Reverse flow is of major concern especially when filtration and such are required.
The main advantage of using a PD type over a centrifuge type is that it can provide a constant flow, even if the liquid is thick. Thus this is useful in breweries and dairy production facilities. Firms involved in the manufacturing of oils in the food market also benefit from the use of PD pumps. Other firms which produce molasses have also started to use these equipment in their overall production and processing lines.
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.
