Rotary Lobe Pump
LQL-25
The most compact frame in the series, for dosing duties and small-bore transfer lines.
- Capacity
- 0.5 – 8 m³/h
- Max. pressure
- 8 bar
- Connection
- DN 25
Precise flow.Reliable performance.
Rotary lobe pumps for food, dairy, chemical and process lines, and internal gear pumps for viscous liquids. The LQL series is manufactured in Konya.
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.

Internal Gear Pump
An internal gear pump for precise, reliable and continuous transfer of liquids from thin to highly viscous, such as oils, resins and paints.
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.
Synchronised drive
The rotors are synchronised through a gearbox and counter-rotate without touching. There is no metal-to-metal contact.
Suction
As the rotors separate, the volume at the suction port expands and the resulting pressure difference draws the fluid into the casing.
Transport
The fluid is carried to the discharge side in the cells between rotor and casing. Wide passages keep shear low.
Discharge
As the rotors mesh again the cell closes and the fluid is delivered to the line. Flow is proportional to shaft speed.
Applications
Start from your process
If you do not yet know which model you need, start from your fluid. Each application page sets out the process conditions, the typical difficulties and the frame sizes that suit them.
