Sanitary Rotary Lobe Pump

Rotary Lobe pumps are used in a variety of industries including food, beverage, pharmaceutical, cosmetics, pulp and paper, coating and painting, oil and gas, daily chemical, and biotechnology. They are popular in these diverse industries because they offer super sanitary qualities, high efficiency, reliability, corrosion resistance and good clean-in-place and steam-in-place (CIP/SIP) characteristics.

Sanitary Stainless Steel Rotary Lobe Pump Application/Operating principles

The pump is a positive displacement lobe rotor pump 

It is ideal for the transfer of viscous as well as low-viscous media in the food-processing. Cosmetics and pharmaceutical industries.

The pump basically consists of two lobe rotors which rotate inside the casing without touching each other.

As the rotors rotate, the space between the lobes and the casing is successively filled with the product which is driven the discharge nozzle displacing a fixed amount of product.

The pumped product forms a continues stream due to the adjusted space of the lobes and the pump casing thus ensuring an efficient pumping.
