Servo Piston Filler

Best Choice For Daily Chemicals Products, shampoo, lotion, detergent, Gel, oil.....

Piston Filling Machine

The piston filling machine application for most of non corrosive liquid,viscous liquid ,oil ,sauce&jam.here we will list some its application and some FAQ

Frequently Asked Questions

The working Generally two steps.

  1. The servo motor or cylinder drives the piston to pump the material from hopper to the piston through the three-way rotary valve or one-way valve
  2. and then the servo motor or the cylinder drives the piston to push the material out through the three-way rotary valve, Entering the container from the filling head; the amount of filling is controlled by the stroke of the servo motor or the air cylinder.

the piston filling machine is mostly using in the fields of daily chemicals,cosmetics, oils. in the food industry ,such as edible oil, sauce and jam, also using the piston filler for filling.

Piston fillers are difficult to clean after usage and thus require high maintenance cost. Chances of leakage is also high with the usage of piston fillers. 

  1. specially design of three way connector without any dead corner
  2. with automatically cleaning system, the user do not need to take off the piston our for cleaning
  3. for different types of liquid, we choose suitable O seals to ensure the long time working and avoid the leakage issues

Npack now mainly produce the latest advantage piston filler,

a. with round U type top tank for easy cleaning on side of machine
b .the piston can be automatically take out for cleaning
c. with cleaning system
d. with safety door and safety sensor, if operator open the safety door, the machine will automatic stop

The NP-VF series volumetric filling system utilizes the delicate servo drive system to control the main filling structure, achieving high stability and precise positioning. With the vertical movement of the filling piston provides long term energy saving and also effectively reduces machine load rate.

Tool-Free Adjustment

Adjustments can be made through the PLC, completely tools-free, giving users a fast and efficient result. The delicate servo control system design provides options for surface layer liquid filling, bottom layer liquid filling, and bottle neck (opening) filling accordingly with different types of liquids.

High Accuracy

The delicate servo system controls the filling amount through precise piston strokes, providing high filling accuracy. The piston is intelligently designed with an adjusting mechanism to enable users to obtain ultimate higher accuracy.


  1. Controlled by Schneider,Siemens and Panasonic servo system.
  2.  automatic adjustable filling speed when working
  3. Designed for easy changeover and cleaning.
  4. GMP standard stainless steel.
  5. Bottom-up filling for option
  6. Individual piston adjustment
  7. Nozzles can set to be above bottle mouth or bottom up, synchronizing with liquid level (beneath or above) to eliminate bubbling of foamy liquids
  8. Three-step-filling, it can fill slowly at the beginning and then accelerate to faster speed, finally slow down once again to finish up. This can prevent foamy liquids from bubbling and avoid spillage
