Desmi Rotan Pumps are globally respected for their outstanding performance in handling highly viscous, abrasive, and temperature-sensitive liquids. Manufactured by DESMI ROTAN — a division of DESMI, one of Denmark’s oldest and most innovative pump manufacturers — these internal gear pumps are engineered for precision, durability, and operational reliability across a wide range of process industries.
Desmi Rotan Pumps are specifically designed for the transfer of thick fluids such as bitumen, chocolate, molasses, oils, resins, polymers, and various chemicals. Their internal gear mechanism allows for a smooth, low-pulsation flow with excellent suction capabilities, making them ideal for applications where product integrity and process efficiency are critical.
Thanks to their simple yet robust construction, Desmi Rotan Pumps are extremely versatile. They are widely used in the chemical, food and beverage, pharmaceutical, petrochemical, and marine sectors, where the safe and efficient handling of challenging media is a daily necessity. Their modular design makes them easy to maintain, with parts that are easily replaceable and serviceable on-site, helping to minimise downtime and reduce overall maintenance costs.
A key advantage of Desmi Rotan Pumps is the flexibility of their construction materials. They are available in cast iron, stainless steel, and other alloy options to match a broad range of chemical compatibility needs. From low-viscosity solvents to high-viscosity polymers, these pumps deliver precise performance while maintaining a long operational life, even under continuous duty.
The internal gear principle used by Desmi Rotan Pumps provides gentle handling of sensitive media, making them ideal for applications where shear must be avoided. This feature, combined with their self-priming ability and high volumetric efficiency, supports industries that demand consistent quality and low product wastage.
Desmi Rotan Pumps are also designed with process efficiency in mind. The pumps can be fitted with heating jackets to maintain temperature-sensitive fluids at optimal conditions during transfer. Options for vertical or horizontal mounting, mechanical seals, and magnetic coupling configurations offer a wide degree of customisation to suit system layouts and environmental requirements.
Another major benefit is their suitability for both batch and continuous processes. Desmi Rotan Pumps can be precisely controlled to match flow rate demands, making them well-suited for metering and dosing applications as well as bulk transfer. Their reliability under pressure and ability to handle challenging media make them a trusted choice for engineers and plant managers alike.
