Single-screw pump ONV 003/36

Operating principle and design of ONV 003/36-07

ONV single-screw pumps are widely used in the dairy, confectionery, processing, and food industries. They are also in demand in the cosmetics, beverage, and chemical industries. These pumps have minimal impact on the product, therefore, they do not damage its structure. This allows for gentle pumping of even sensitive media.

As a result, these pumps are used for cream, fermented milk products, and curd-whey mixtures. They are also suitable for condensed milk, ice cream mixtures, wort, and juices, including juices with pulp. Furthermore, the equipment can handle yeast and thick sediments, wine materials, and wines. Thus, its application is universal.

Key benefits and adaptability

The design is based on a rotor-stator pair. A metal rotor rotates inside an elastomer stator, creating isolated cavities that move the product from the suction port to the discharge port. This results in a uniform, pulsating flow.

The main advantage is gentle transportation. For example, the pumps handle liquids of varying viscosities. They also handle abrasive or fragile particles. As a result, the product is not damaged.

The equipment is highly adaptable. It is manufactured from various grades of stainless steel. The stator material is also individually selected. EPDM or Viton are used for aggressive environments. Food-safe rubber or Teflon are used for food products. Therefore, the pumps are suitable for neutral, acidic, and abrasive environments.

Operational advantages

Maintenance and repair are very simple. The design allows for quick replacement of wearable components. For example, the stator can be replaced without dismantling the pipelines. Consequently, line downtime is minimal.

Furthermore, the pumps are self-priming, simplifying their integration into the system. They operate smoothly and quietly. Also important is the absence of vibration and cavitation. As a result, the process remains stable and the product quality is preserved.

In conclusion, the ONV 003/36-07 pumps are a reliable and cost-effective solution. They ensure uninterrupted operation and high product quality.
