5 Reasons to Choose Positive Displacement Pump

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.
