Lobe pump types are distinguished from each other by their technical and design features. Lobe pumps are known as valveless and positive displacement pumps to transport dense liquids. The most important feature of these pumps is the lobe design. Thanks to this technical feature, the fluid between the lobes rotating in opposite directions and the body is moved up to the pump outlet. In general, it is necessary to examine more closely what lobe pumps used in some sectors do.

What are the Lobe Pump Types and What Does It Do?

Lobe pump variants have certain functional features. The fact that each of them has different technical features distinguishes these pumps from each other. But the function of every lobe pump is to transport dense liquid. We can explain the lobe pump types as follows:

Bellin PLGP Series Lobe Pumps:

They are pumps that provide medium and high viscosity fluid transfer. This type of lobe pump, which can operate in both directions and provides pulse-free flow, stands out with its effective operation. Bellin Lobe Pumps, which provide high pump efficiency, have a compact design. It is especially used for the transfer of wastewater, sludge, liquid fertilizer etc. fluids. There are stainless steel and cast steel alternatives. For the lobe material, there are EPDM, Viton and NBR alternatives.

Prolobe PLBP Series Stainless Steel Lobe Pumps

This lobe pump, which has a simple and compact design, has particle permeability. It is used in industrial areas as it provides medium and high viscosity fluid transfers. It is especially preferred in the food, chemical and cosmetic industries. These positive displacement pump types provide high pump efficiency. It offers flange, threaded or triclamp connection alternatives with 316 or 304 quality stainless steel body and lobe options.

Each type of lobe pump has a different usage area. It is necessary to select the pumps with different technical and physical features in accordance with the sector, fluid and required outlet pressure.

Features and Advantages of Lobe Pumps

Lobe pumps stand out with their different technical and design features. Its most important feature is that it effectively transfers high-viscosity and granular products. It transfers the solid particulate products without disturbing their properties. Another important feature is that the lobes rotate without touching each other. In this way, the service life is extended without any wear. Lobe pumps can have two, three, four or more lobe (tip) numbers. This number generally varies according to the usage area, that is, the type of fluid to be transferred. In addition to all these features, lobe pumps have some advantages:

• It has a durable and long-lasting pump system.
•  It has the potential to transfer various types and particulate fluids. Because it can resist against excessive pressure.
• Provides on-site cleaning and sterilization advantages. All components in the pump can be accessed by simply opening the front cover without removing the pump from the pipe line.
• It has a structure that provides variable speed control. Thus, it is possible to easily change the flow rate and maintain efficiency by using a frequency inverter.
• Generally works without vibration and noise.
• It can handle liquids or particulate fluids in different viscous ranges. Thus, it offers the advantage of flexible product processing.

In Which Areas Are Lobe Pumps Used?

Lobe pumps can be used in many industries. One of the most used sectors is the food industry. It efficiently transfers fluids with variable viscous properties with its agitation and shear properties. Another area where lobe pumps are needed is the chemical industry. Precise product transfer, self-cleaning and efficient processes make the products in this industry the best. On the other hand, we can state that it is also used in the pharmaceutical industry. These pumps can be used in dosing operations with low carbon content construction materials and high precision.

They are preferred for the transfer of fluids such as sludge and wastewater in drinking water and wastewater treatment plants, and for the transfer of fluids containing waste materials in fertilizer and biogas plants due to their solid permeability and ease of maintenance.
