Piston fillers


Volumetric piston fillers dose accurately, are reliable and easy to use for the packaging of liquid, semi-dense, and dense products.

Pneumatically operated volumetric dosing machines, of extreme precision, reliable and easy to use, for the packaging of liquid, semi-dense and even highly dense products, with and without suspended pieces, in any type of container.

Doselite dosing pumps offer:

  • Extreme precision in dose repeatability
  • Versatility: all parts in contact with the product are made of AISI 316 stainless steel; therefore, they are indicated for use in the food sector, for the packaging of sauces, jams, pesto, meat sauce, yoghurt, mayonnaise, ketchup, and in general for pet food in cream or sauce, chemistry, for the packaging of solvents, paints, varnishes, pastes, resins, glues, in the field of cosmetics and herbal medicine for the packaging of creams, perfumes, nail polishes and gels, shampoos, scrubs, oils, masks, liquid foundations, mascaras, lip glosses and of the pharmaceutical industry for the packaging of creams, syrups, liquid and thick preparations for pharmaceutical and veterinary use.
  • Wide range of controls that allow you to check and intervene on pressure, temperature, dispensing speed and suction speed.
  • Flexibility and ease of use, materials and specific certifications make the Doselite range the most suitable and professional solution for any packaging line

All Tenco dosing syringes can be moved pneumatically or via brushless motors, the latter guaranteeing even more precision in dosing and can be perfectly integrated into automatic production lines. Doselite can also be customized according to needs with a base to be positioned on a bench or trolley with dosing pump at the top or bottom or, again, integrated into automated packaging lines.

The dosing pistons can also be equipped with resistances to keep the product at a predefined temperature and they can still be combined with simple loading hoppers, heating groups, mixers or pressing systems, to facilitate the aspiration of the product to be dosed. Ultimately, each machine can be built with the most suitable configuration for the specific needs of the user.

Do you still have any doubts? Here you will find all the answers you need.

Can I use Doselite for filling at high temperatures?

Yes, our Doselite piston doser can be used for the packaging of any liquid or dense product, even at high temperatures (over 100 degrees). All gaskets in contact with the product are made of food-grade silicone and PTFE (depending on the type of product to be dosed) and every part in contact with the product is made of 316L stainless steel, so they can work without problems with any type of product, even at high temperatures.

Can I aspirate the product directly from the cooker or from the storage drum with Doselite, or do I need a product transfer pump inside the hopper?
All of our Doselite piston dosers can be customized according to production needs, therefore they are completely modifiable. Depending on the type of product to be dosed and the positioning of the cooker and/or storage tank, our Doselite piston dosers can be fed with a loading hopper or suck the product directly from the cooker, from the product processing robot (e.g. example, a Roboqbo robot), just connect the Doselite to the cooker via a flexible hose, without the aid of any transfer pump, the machine is able to aspirate and dose the set quantity of product with extreme precision, in complete cleanliness and without waste . For small doses, however, we always recommend the use of a loading hopper.
How do I adjust the amount of product to be dosed with Doselite?

The quantity of product (volume of product) to be dispensed is easily selected using the dose adjustment handwheel which is positioned on the back of the dosing pump. The handwheel adjusts the stroke of the piston and consequently the volume to be dispensed. There is also a reference numeric counter to increase or reduce the stroke cycles of the piston and, consequently, the quantity of product to be dispensed.

How can I wash the Doselite dispenser after use?
The Doselite piston doser and the relative accessories that come into contact with the product are all completely washable, removable and sanitizable. All parts in contact with the product can be easily disassembled using the clamp connections, therefore it is not necessary to use any disassembly tools. We recommend cleaning the machine after each packaging cycle, sucking up some water (even hot, with a high degreasing power) and a neutral ph degreasing product and/or any cleaning product compatible with the previously packaged product. Subsequently we recommend carrying out a packaging cycle with clean water. For greater cleaning safety of each component, we recommend, however, the disassembly of the valves and the dosing cylinder and the relative gaskets (therefore only the parts that have come into contact with the product).
Is it possible to apply an inlet filter also on the Doselite dispenser? Can I apply the Tandem or Tandem Professional filter?

For the filtration of some liquid products it is also possible to insert a filter holder at the inlet of the Doselite volumetric doser. This filter holder must also be equipped with filter cartridges (available in fiberglass and steel). The filter cartridges to be used with Doselite have the same characteristics as those used with Enolmatic and Enolmaster, however they are not the same, as they have different dimensions.

Is the Doselite fully pneumatic? What type of compressor should I use?

The Doselite is fully pneumatic in operation, therefore no electrical power supply is required, but it does require a compressor or compressed air system. We recommend using a compressor with the following minimum requirements: tank capacity 80 Lt, air flow 300 litres/minute, power 1.5Hp, possibly silenced and absolutely not lubricated. It is advisable to use an anti-condensation filter or a dryer to avoid any damage to the pneumatic components in case of particularly humid environments.

What is the maximum viscosity that can be dosed with Doselite?

The viscosity of the products to be treated varies greatly and can depend on different factors. In fact, it is possible to use systems for pressing, heating or mixing the product and this can facilitate the aspiration of the product itself. For the dosage of a product at room temperature, it is generally possible to indicate a maximum viscosity of 50,000 cPs. However, it is always advisable to send a sample of the product to be tested in the workshop.
