How does a SOMA Sinuspump work?  

The operating principle of the sinuspump, invented in 1982 by Manfred Sommer, founder of MASO Prozesspumpen and SOMA Pumps GmbH, is based on the displacement principle, allowing for uniform and efficient transport of liquids.

 

What is the core component of the SOMA SINUS SODIAL® pump?  

The core component of the SINUS pump is a sinusoidal curve mounted on a drive shaft as a disc (rotor). This element moves sinusoidally within the pump chamber, enabling continuous and uniform liquid transport.

 

How do the suction and pressure phases of the sinus pump work?  

Suction phase: When the sinusoidal rotor retracts (in the direction that increases the pump chamber), a vacuum is generated in the pumping chamber. This movement draws the medium from the inlet into the pumping chamber, resulting in a suction force equivalent to 85% of a vacuum.

 

Pressure phase: When the displacement element (rotor) moves forward (in the direction that decreases the pump chamber), the liquid is gently and consistently discharged from the pumping chamber.

 

Sinusoidal movement:  

The sinusoidal motion of the rotor ensures that the transport of the medium in the pump chamber is evenly distributed across four equally divided chambers. This minimizes pressure peaks and pulsations, which is particularly important for the gentle transport of sensitive or viscous media.

 

How is the separation of the suction and pressure sides achieved?  

A sealing scraper separates the suction and pressure sides of the pump, allowing for pressure equalization and preventing backflow. With the constantly open suction side, the viscosity of the products becomes irrelevant. This supports the production of high-viscosity products, such as silicones or frozen orange juice concentrate, as well as low-viscosity commercial goods similar to water. Additionally, the pump avoids potential foaming and liquid separation.

 

What are the advantages of the SOMA sinus pump?  

 

1. Gentle transport: The SOMA sinus pump operates on a gentle transport principle, ensuring that the medium is treated carefully and guaranteeing high product quality. The sinusoidal motion prevents the product from being crushed or foamed, leading to better consistency and quality.

 

2. Uniform flow rate: Continuous and even liquid flow is achieved, as the sinusoidal movement generates a steady stream.

 

3. Pulsation-free operation: The SOMA SINUS SODIAL® sinus pump transports products with almost no pulsation, preventing foaming or damage to the product.

 

4. High suction capability: Due to the unique design and the sinusoidal movement of the rotor, SOMA SINUS SODIAL® pumps achieve a suction force of -0.85 bar.

 

5. Low shear forces: The sinusoidal movement ensures that the liquid is transported evenly and gently, minimizing shear forces that can lead to the breakdown or alteration of sensitive products.

 

6. High discharge capacity: SOMA SINUS SODIAL® pumps are available in six different sizes, with a discharge capacity of up to 90,000 liters per hour.

 

7. Low maintenance requirements: SOMA sinus pumps are designed for easy access to all components (including the mechanical seal), allowing for quick inspection and maintenance without the need to remove the entire pump (inline maintenance).

 

8. Bidirectional operation: SOMA sinus pumps can operate in bidirectional mode. This is particularly advantageous when back-pumping is necessary.

 

9. Hygienic design: SOMA sinus pumps meet the highest quality standards and are standardly certified by FDA (Food and Drug Administration), as well as EG1935-2004 and 3.1.

 

10. Clear separation of pump head and bearing block: SOMA SINUS SODIAL® sinus pumps feature a distinct separation of the pump head and bearing housing, preventing product contamination.

 

Why are sinus pumps energy-efficient?  

SOMA Pumps' sinus pumps reduce CO2 emissions and electricity costs compared to conventional displacement pumps. The decreased mechanical stress, optimized flow conditions, and gentle transport mechanism lower energy consumption by up to 50%.

 

How is a sinus pump cleaned?  

The cleaning of a sinus pump can vary depending on the application and the media being pumped. SOMA sinus pumps can be cleaned by CIP (Clean-in-Place), SIP (Sterilization-in-Place), or manually.

 

Where is the sinus pump used?  

Sinus pumps are ideal for transporting food, beverages, cosmetics, dairy products, chemicals, and confectionery products. They are particularly suitable for the gentle, low- and high-viscosity, pulsation-free transport of liquids with large, chunky components and shear-sensitive ingredients.
