High Pressure Positive Displacement Pump: Make The Clever Selection

There are several pump options in the market and without the basics, you might not make the right choice. It is for this reason that it pays to understand which features to look for and which type is appropriate for what use. Ideally, there are the centrifugal and the high pressure positive displacement pump simply the PD pumps.Both are suitable for industrial use as well as home application. However, the question on which one to use and when is best answered depending on the requirements and the expectations.


There are particular situations that will make it the ideal choice over the centrifugal ones. As such, you need to carefully consider your application process and determine if one or more of the said conditions are necessary. Otherwise, the pumps are distinct in terms of behavior, efficiency, and the area of application.


The other important advantage is that they require low shear pumping. Even though the liquid shear may not be a problem in most cases, there are applications where the liquid shear is critical. Good examples include latex paint and tomato paste. High pressure process pumps are known to excel in handling liquids and fluids that are shear sensitive.


The second consideration is the flow. Normally, the centrifugal pumps will run off to its BEP whenever the lower flow is necessary. This causes excessive consumption of energy. In addition to energy wastage, it causes the damage and poor performance as whole. With positive displacement, however, these types of pumps are well suited to provide a constant flow at any desired speed, thus offering a better choice for situations for different pressure of flow speed.


When the liquid being pumped is insufficient, gas pebbles tend to build up. Most pumps drastically drop in efficiency, and some may not even at all if there is a gas bubble formation in the suction. This is due to the loss of prime. In the case of PD pumps, this is not the case. It continues to operate efficiently even when there is a high percentage of air in the fluid being pumped. In addition to this, it is well suited to handle fluids that need high pressure to be pumped such as sandblasting applications and high-pressure water-cutting technology.


In addition to this, it operates at a constant speed, delivering a constant flow even with varying system pressure. This means that it may not be affected much with the atmospheric condition which is a very desirable characteristic in certain conditions and environments.


Most users also like its ability to operate at a constant speed, thus delivering a constant flow even when the pressure varies. This feature makes it an ideal solution in conditions where the atmospheric conditions as well as other external factors are likely to vary. It also helps limit slip thus making it very ideal for applications that incorporate metering for consistency and accuracy.


It is clear that there is need to carefully consider your situation before settling on any given alternative. It begins by understanding your needs and unique requirements and matching them to those offered by the different alternatives. However, you can enlist the services of a trusted expert to offer assistance and guidance in buying, as this assures you that you get the best that the market has to offer at a fare price. In addition to this, an expert also helps you ensure that the brand you select has spare-parts and can easily be serviced when the need arises.
