Increase Production Efficiency with MSD’s Precision Filling Nozzles

It is easy to overlook the humble nozzle when focusing on the broader aspects of your liquid-filling production line. However, these unassuming components play a vital role in ensuring accuracy, efficiency, and overall product quality. Filling nozzles directly control the flow of your product, ensuring proper tube fill levels and minimising spillage.

The sheer variety of nozzle options can seem overwhelming. When selecting the ideal nozzle for your application, consider these key factors:

  • Liquid Viscosity: Thin, watery products and thick, viscous liquids require different nozzle designs to optimise flow and prevent clogging.
  • Fill Type: Will you be using a standard fill, a bottom-up fill to reduce foaming or another specialised method? Your filling technique influences nozzle choice.
  • Hygiene Standards: Industries like pharmaceuticals and food & beverage demand nozzles designed for easy cleaning and sanitation to meet stringent regulations.
  • Product Compatibility: Ensure the nozzle’s materials are chemically compatible with your product to avoid contamination or degradation.

Let’s take a closer look at some nozzle types and their uses:

Straight-Through Nozzles: The Versatile Workhorse

Straight-through nozzles are the most common type of nozzle found on liquid filling machines. Their open design allows for unrestricted flow, making them ideal for a wide range of products. These nozzles come in various sizes and lengths to accommodate different pumps, containers, and production needs.

Ball-Check Nozzles: Preventing Drips and Spills

Ball-check nozzles feature a spring-loaded ball mechanism that opens under product pressure and closes when the flow stops. This design helps minimise dripping and product waste, especially for slightly more viscous liquids. In many production lines, ball-check nozzles or straight-through nozzles will effectively meet your filling requirements.

Valve-In-Tip Nozzles: Precision Control for Stringy Products

Valve-in-tip nozzles provide the solution for applications where dripping or stringing is a significant concern. These nozzles have a positive shut-off mechanism at the tip, ensuring a clean cut-off of thicker liquids like honey, creams, gels, and lotions. Valve-in-tip nozzles are often integrated with gear pumps, lobe pumps, and flow meters for maximum precision.

Purge Nozzles: Eliminating Oxygen for Product Integrity

Purge nozzles are specialised for applications where removing air or oxygen from the container is critical. Using a dual-nozzle design, they purge the container with an inert gas (often nitrogen) before or after filling. Purge nozzles are essential in pharmaceutical and biotech industries to prevent product deterioration.

One Pump, One Nozzle: The Key to Accuracy

MSD Ltd’s commitment to accuracy and consistency is reflected in our “one pump, one nozzle” philosophy. This approach ensures that each metering system has a dedicated nozzle, maximising filling accuracy across all containers. This practice promotes superior control and reliability, especially in demanding industries.

Nozzle Size Matters

Nozzles are available in various diameters and lengths to suit different products, containers, and filling speeds. Choosing the right nozzle size depends on factors like liquid viscosity, container opening, and desired fill rate.

Disposable vs. Reusable: Convenience vs. Longevity

Disposable nozzles, often made of plastic, offer a maintenance-free solution for single-use filling systems or corrosive products. Reusable stainless steel nozzles, on the other hand, are the preferred choice for most applications due to their durability and compatibility with a wide range of liquids. While reusable nozzles require cleaning, their long-term benefits outweigh the minor maintenance.


We hope this helps explain the different types and functionality of nozzles in the tube filling industry. Do not hesitate to contact us if you need help determining the perfect filling nozzles to meet your needs. We will ensure you are supplied with the ideal solution for your operations.
