The Consumables

Poly Dispensing Systems (PDS) dispensing needles are fully compatible with our syringes, thanks to the Luer Lock connection system.

Each needle, whether packaged in bulk or in box, is assigned a unique lot number. Our commitment to manufacturing excellence is reflected in our strict production tolerance, ensuring reliable and precise products every time.

Our needles follow a universal color-coding system, allowing for quick and easy identification. They are available in various lengths, from 0.25 to 1.5 inches, and in a range of standard gauges from G14 to G32. This variety allows us to meet the specific requirements of each application, ensuring optimal performance.

For added protection against UV rays, we also offer a UV-barrier option, providing stability for light-sensitive materials.

All our syringes are made of polypropylene, silicone-free certified, and equipped with a Luer Lock outlet for easy needle attachment. They can withstand burst pressures of up to 20 bar. Thanks to our high-quality manufacturing and quality control processes, we ensure consistent repeatability in production.

Our syringes are available in three different colors:
Clear, for use with all types of non-UV-sensitive fluids.
Amber, providing UV protection between 240 and 550 nm while allowing fluid level visibility during dispensing.
Opaque black, ideal for fully blocking light when using adhesives or photosensitive fluids.

We offer two syringe ranges, both compatible with all our pneumatic dispensers and suitable for feeding our dispensing valves.

All our pistons are made of polyethylene and are guaranteed silicone-free. When paired with our syringes, they can withstand burst pressures of up to 20 bar.
Thanks to our rigorous manufacturing processes and systematic quality control, we ensure repeatability in the production of our syringes and pistons.

We offer two piston ranges:

• Standard pistons, compatible with standard AirPulse syringes
• OPTI pistons, exclusively designed for use with our OPTI syringes

The standard piston range includes a variety of models with varying levels of fit, depending on the viscosity of the dispensed fluid. These include DripFlow pistons, SW Flow pistons, white double-lip standard pistons, and neoprene and rubber pistons.

To ensure optimal dispensing and proper fit within the syringe, the piston must accompany the product throughout its flow, even when no pneumatic or mechanical pressure is applied.

The OPTI piston range is characterized by its double-lip design, which helps eliminate trapped air and prevent leaks.

In addition to our standard consumables range, PDS also offers the Semco™ line, from a leading global manufacturer primarily active in the aerospace sector. This range includes dispensing cartridges, cartridge holders, nozzles, and other related products.

Static mixers have an elongated shape similar to a syringe but are much narrower, and they attach to the end of two-component cartridges. Designed for the rapid mixing of dual-component fluids, they are intended for single use.

Equipped with an integrated mixing element, these mixers enable the two fluid components—part A and part B—to interlace as they pass through a series of helices inside the specially designed tube. This interaction occurs just seconds before application, ensuring uniform dosing and a precisely controlled mix.

Moreover, the two components only come into contact inside the static mixer, preventing premature mixing. This is especially advantageous for fast-reacting materials, as it helps avoid contamination of the dispensing system and minimizes the risk of equipment damage.

There is an almost unlimited variety of static mixers, with different inlet and outlet shapes, sizes, and dimensions to suit a wide range of needs. For example, “Turbo” mixing nozzles, with a square internal shape, allow for a shorter mixer length while maintaining the same mixing performance—thereby speeding up the mixing process over a compact distance.

The choice of static mixer depends on several parameters, including:

• The viscosity difference between the two materials to be mixed
• The ratio gap between the two components
• The expected flow rate, as well as the required length and diameter

Key elements to define when selecting a static mixer:

• Inlet and outlet type
• Inner diameter
• Inlet tip diameter
• Outlet tip diameter
• Number of mixing elements
