Multi-Head Piston Dispensers: Precision Filling for Viscous Products
Multi-head piston dispensers feature two or more piston cylinders, with each cylinder operating an independent dosing nozzle. Benchtop configurations typically include 2, 4, or 8 dosing units, with dual-nozzle semi-automatic dispensers being the most popular due to their operational efficiency and 2X productivity versus single-head models.
LOCUS PACKAGING supplies semi-automatic, multi-station piston dispensers for high-accuracy filling of viscous products. Ideal for laboratories and production lines handling creams, adhesives, food pastes, or pharmaceutical gels.
Key Features:
Modular Design: Configure with 2–16 dosing heads for batch processing.
Viscosity Range: Handles products up to 1,000,000 cP (e.g., silicone sealants, peanut butter).
Accuracy: ±0.5% deviation with ceramic/piston cylinders.
Quick-Change Kits: Swap containers in <3 mins (tubes, bottles, cartridges).
Cosmetics: Filling lip gloss, creams, serums, and hair gels.
Pharma: Dispensing ointments & sterile gels.
Food: Portioning sauces, peanut butter, dressings, batter, batters, and fillings.
Chemicals: Packaging sealants, lubricants, adhesives, and acids (including Class I Div. 1).
Industrial: Sealants, lubricants, resin compounds
Technical Highlights:
Materials: SS304/316L, PTFE, ceramic wetted parts.
Dose Range: 0.5ml to 5L per cycle.
Compliance: FDA 21 CFR 117 (food), ISO 9001.
Simultaneous Dual-Container Filling: Operators dose into two containers with one foot-pedal activation
Independent Calibration: Different volumes per cylinder (e.g., 50ml + 100ml) for mixed-container filling
Orientation Flexibility: Vertical or horizontal piston alignment
