Lobe pump is one of the valveless and positive displacement pump types. Lobe pumps are used to transport liquids and gases at high pressure. These pumps, which use high viscosity without damaging the structure of the substance, are similar to gear pumps. It is preferred in many applications because it enables the transfer of high density fluids. In particular, the food industry is one of the sectors where lobe pumps are used most. Since this special equipment has many functional features, it serves its usage areas.

What is a Lobe Pump?

Lobe pumps are equipment that enables the transfer of high viscosity and granular structured fluids. Made of stainless steel, these pumps are resistant to corrosion. Thanks to these features, it is suitable for use in the food and chemical industries. Providing high efficiency and hygiene, lobe pumps are one of the indispensable equipment of industrial areas today. Other features of these pumps are:

● It is easy to clean.

● There are 4 different rotor options: 2 lobe rotor, butterfly rotor, 3 lobe rotor and single butterfly rotor,

● The body, rotor and shaft are made of stainless steel.

● There are threaded, flange or clamp connection models.

● Since the parts other than the pump head are coated with epoxy paint, it is suitable for long-term use.

● It is easy to use as it provides high security.

● It has hygiene in accordance with food standards.

● The rotors move in the opposite direction.

● Since it has a large pumping chamber, it can transfer substances without damaging their structure. Products are transported in the spaces between the lobes and the casing.

● It is designed with a special heat jacket for the transfer of materials that may freeze. Lobe pumps with heat jackets heat the front cover or the entire body and transfer the substances that may freeze without freezing.

● Seal, motor and other parts can be changed according to the usage area.

● Since it has the features of cleaning in place and sterilizing in place, it is used in CIP (Clean in Place) and SIP (Sterilise in Place) processes.

Why Are Lobe Pumps Preferred?

Lobe pumps are preferred because they provide many benefits in their areas of use. The most important advantage of its preference is that it provides efficiency in industrial areas. It is suitable for use in the transfer of all fluids, regardless of low, medium and high. On the other hand, it does not cause loss of time because it is easy to install and maintain.

One of its outstanding features is that it is made of stainless steel. Thanks to this feature, it is resistant to corrosion and offers perfect hygiene. Designed for the transfer of sticky, sensitive and corrosive fluids, this special type of pump is suitable for industrial use.

How Does a Lobe Pump Work?

 Lobe pump has a certain operating principle. By design, it consists of lobes placed on two  parallel axes. These lobes separate from each other without touching each other, thus creating a gap. Each of the rotors placed in parallel is designed with lobes. Therefore, it has an internally integrated mechanism. Since the rotors rotate without touching each other, a gap occurs.

The lobe pump captures the fluid from the gap and pushes the fluid into the gap with the rotation of the rotors. As the rotors rotate, the lobe gaps are filled by suction. With the effect of this movement, it moves towards the pressure side. Thanks to this way of functioning, the fluid is constantly advanced and transferred.

In Which Areas Are Lobe Pumps Used?

Lobe pumps are used to transfer high viscosity & density liquids that are difficult to transfer in different industrial areas. Food, pharmaceutical and chemical industries are among the sectors where it is most used. It provides the transfer of many fluids such as cake, jam, marmalade, gelatinous substance, cream and dough. On the other hand, it is useful in transporting chemicals and oils. To summarize, lobe pumps are used in the following areas:

● Food processing

● Chemical industry

● Pharmaceutical production

● Petrochemical

● Cement production

● Wastewater treatment plant

● Biotechnology
