LQL series, with its geared motor on a common baseplate

High Efficiency

Low internal slip and stable volumetric efficiency put flow under the direct control of shaft speed.

Hygienic Design

Casing geometry that limits dead volume, with seal arrangements suited to a CIP regime.

Long Service Life

Wear parts are changed through the front cover. The pump stays coupled to the line and to its drive.

Local Manufacturing

Design practice carried over from American and German engineering work, executed on our production line in Konya.

Four rotor geometries, one hydraulic principle

Liquilob combines engineering, precision machining and long-life performance in rotary lobe pump technology. Each rotor geometry is optimised for a different process requirement, and choosing the right rotor matters as much as choosing the right frame size.

How a rotary lobe pump works

A positive displacement principle. Two rotors that never touch carry the fluid in cells between themselves and the casing.

  1. Synchronised drive

    The rotors are synchronised through a gearbox and counter-rotate without touching. There is no metal-to-metal contact.

  2. Suction

    As the rotors separate, the volume at the suction port expands and the resulting pressure difference draws the fluid into the casing.

  3. Transport

    The fluid is carried to the discharge side in the cells between rotor and casing. Wide passages keep shear low.

  4. Discharge

    As the rotors mesh again the cell closes and the fluid is delivered to the line. Flow is proportional to shaft speed.

Quality is not a single product characteristic. It is a company-wide approach that runs from design to after-sales service.

Profimann is an engineering company developing high-efficiency, long-life fluid-transfer solutions. The rotary lobe pumps it produces under the Liquilob brand are designed for applications that demand hygiene, precise flow control and stable operation in difficult conditions.
