Why Choose a Positive Displacement Pump?
For industries such as dairy, meat processing, food and beverage, and more, it’s important to choose the right pump. However, it’s especially critical for the chemical processing industry due to the chemicals involved. This is why it depends on quality positive displacement pumps.
When it comes to positive displacement chemical pumps to process oil, automobile paint, juices, etc., always work with a trusted source. That way, you have the assurance that the equipment will work seamlessly. This is especially important for the chemical processing industries.
Understanding Positive Displacement Chemical Pumps
Many industries use centrifugal pumps. While these serve an important purpose, they’re not always the right choice. The displacement positive type of pump is the better option for many applications in the chemical processing industry.
In simple terms, this pump displaces a known volume of liquid for every cycle completed. The flow rate is always in proportion to both the speed and number of cycles.
Types of Industrial Pump Systems in Canada
The chemical processing industry uses positive displacement pumps for four primary types of applications. These include:
1. High Viscosity
The problem with centrifugal pumps for this particular application is they struggle to handle viscous liquids. As viscosity increases, centrifugal pumps become more and more inefficient to the point where they will not pump the product at all. In comparison, positive displacement industrial pump systems can move thick liquids with ease.
In some instances of low flow, a centrifugal pump, run off its BEP, works fine. However, this usually diminishes the pump’s performance, uses more energy, and can cause damage.
Positive displacement pumps are a much better solution. For low flow scenarios, this type of pump provides a constant flow of liquid regardless of operating speed. You’ll achieve better performance when trying to achieve the required flow at varying pressure.
Considering that positive displacement chemical pumps deliver constant flow, they’re a perfect choice for metering applications. Some examples of the specific pumps for this include :
4. High Pressure
For applications that require high pressure, you can’t beat positive displacement pumps. Some of the models available today are so advanced they can produce more than 1000 psi.
As a bonus, you can also consider positive displacement industrial pump systems for shear-sensitive liquids. Centrifugal pumps typically operate at higher speeds and rely on their ability to shear the liquid. They put sensitive liquids at risk of shearing. So, for shear sensitive chemicals, they’re not a viable option.
What Makes Positive Displacement Chemical Pumps So Great?
Specific to chemical processing, these pumps maintain a constant flow at variable pressures. Chemical processing companies depend on industrial pump systems in Canada because operation pressure doesn’t affect them.
Something else worth noting is that positive displacement chemical pumps easily handle many different fluids. Some can self-prime, have a seamless design, and are between 10 and 40 points more efficient than centrifugal pumps.
