Automatic Servo Based Piston Filling Machine
High-Performance Filling for High-Viscosity Liquids
The Harsiddh Automatic Servo Based Piston Filling Machine (HSPF Series) is a state-of-the-art volumetric system designed for industries where repeatable accuracy is non-negotiable. By replacing traditional mechanical linkages with advanced servo-motor technology, this machine provides superior control over the piston stroke, making it the most reliable solution for the pharmaceutical, cosmetic, and food processing sectors.
Advanced Operational Workflow
The machine’s synchronized system ensures stable container handling and precise volumetric displacement.
Sequence of Operation:
- Container Indexing: Bottles are fed via an SS slat conveyor and held in place by pneumatic indexing gates.
- Volumetric Suction: The servo-driven piston draws the exact volume of product from the integrated 120L storage tank into the cylinder.
- Controlled Discharge: Diving nozzles descend into the bottles, and the piston dispenses the product with a programmed speed profile.
- Drip Prevention: Once the fill is complete, the pneumatic shut-off valve closes instantly to prevent trailing or leakage.
- Release: Filled bottles are released and moved forward to the capping and labeling station.

Frequently Asked Questions
Can this machine handle both thin liquids and thick pastes?
Yes. One of the greatest strengths of the Servo Piston mechanism is its torque consistency. It provides the necessary power to pull and push high-viscosity products like creams, honey, peanut butter, and thick gels, while also maintaining the delicate control required for water-thin liquids like syrups or perfumes.
How does the "Multi-Stage Filling" feature work?
Because the piston is controlled by a programmable servo motor, the machine can perform profile filling. This means it can start with a "Fast Fill" to save time, and automatically switch to a "Slow Dribble" at the end of the cycle. This feature is essential for preventing splashing in wide-mouth jars or foaming in narrow-neck bottles.
What is the typical changeover time for different products?
Changeover is exceptionally fast—usually taking less than 10 to 15 minutes. Since the fill volume is digital, you can save specific "Product Recipes" in the PLC memory. When switching from a 200ml bottle to a 1000ml jar, the operator simply selects the preset on the screen, and the pistons automatically adjust their stroke length.
Is the machine easy to clean and compliant with cGMP?
Absolutely. As a cGMP-compliant model, the machine is built with a rigid Stainless Steel 304 frame, and all liquid contact parts are AISI Stainless Steel 316L. The pistons are designed for easy dismantling without specialized tools, and the system can be integrated with a CIP (Cleaning-In-Place) unit to ensure maximum hygiene for pharmaceutical and food applications.
