Frequently Asked Questions
Learn about line integration, spare parts supply, and overseas technical support.
Q What types of pumps does ZSYAN provide for liquid packaging?
We equip our machines with three pump types depending on viscosity: (1) Pneumatic or Servo Piston Pumps for pastes, sauces, and lotions; (2) Peristaltic Pumps for low-viscosity sterile liquids and pharmaceuticals; (3) Magnetic Gear Pumps for thin oils and beverages.
Q Can the liquid machines handle heated viscous paste filling?
Yes. Our hoppers can be fitted with electric water-jacket heating (up to 95°C) and motorized scraper agitators to maintain fluidity and uniform suspension.
Q How does ZSYAN prevent dripping on pouch sealing jaws?
All filling nozzles incorporate a pneumatic suck-back cut-off mechanism that draws excess droplet back at the moment of stroke completion, ensuring clean, leak-proof seal areas.
