It is critical to select the correct pump for businesses such as dairy, meat processing, food and beverage, and others. However, because of the chemicals involved, it is especially critical for the chemical processing industry. This is why reliable positive displacement pumps are required.
When it comes to
positive displacement chemical pumps for processing oil, vehicle paint, juices,
and other liquids, always go with a reputable manufacturer. That way, you may
be confident that the device will function properly. This is particularly
critical for the chemical processing industries.
The choice between
a positive displacement and a centrifugal pump is not always obvious. They each
have very different behaviors, and it may be difficult to grasp how a positive
displacement pump could fit into your process if you are unfamiliar with them.
In some cases,
positive displacement pumps are more efficient than centrifugal pumps. If any
of the following conditions or applications apply to your process, a positive
displacement pump should be employed.
High Viscosity
Centrifugals
struggle to pump viscous liquids, becoming inefficient at even low levels.
Positive displacement pumps, on the other hand, can handle thick liquids with
ease.
Extremely High
Pressure
Positive
displacement pumps are unrivaled in high-pressure applications. Some models on
the market now are so advanced that they can create greater than 1000 psi.
Positive displacement
industrial pump systems for shear-sensitive liquids are an added feature.
Centrifugal pumps are typically faster and rely on their ability to shear the
liquid. They expose delicate liquids to shearing. As a result, they are not a
suitable alternative for shear-sensitive compounds.
Flow Rate Is Low
In some cases of
low flow, a centrifugal pump powered by its BEP works perfectly. This, however,
frequently reduces the pump's performance, consumes more energy, and can cause
damage.
Positive displacement
pumps are a far superior option. This type of pump offers a steady flow of
liquid regardless of operating speed in low-flow circumstances. When attempting
to achieve the required flow at varying pressure, you will achieve better
results.
Metering
Positive
displacement chemical pumps are ideal for metering applications because they
provide continuous flow. Here are some examples of pumps for this:
- Diaphragm
- Gear
- Peristaltic
- Piston
- Plunger
Shear
Sensitive Liquids
When compared to positive displacement pumps, centrifugal pumps typically operate at higher speeds. Because higher speeds can shear liquids, centrifugal pumps are unsuitable for liquids such as tomato paste and latex paint. Positive displacement pumps that operate at lower speeds are gentler on products and are typically favoured in these applications.
Conclusion
These reasons make
the Progressive Cavity Pump the best for the industry. Positive displacement
pumps and centrifugal pumps function extremely differently. Understanding their
behaviours can assist you in selecting the best one for your application. When
