How to use this guide
Use this guide to prepare your requirements. Contact us if you need help choosing a configuration.
Peristaltic, piston and magnetic-pump filling systems move liquid in different ways. The right choice cannot be made from viscosity alone. Product chemistry, particles, foam, dose range, container opening, cleaning, product recovery, output and the required acceptance method all affect the configuration. This guide provides a comparison framework; it does not assign any material to a pump without compatibility evidence and a representative trial.
1. Define the product under operating conditions
Provide the material name, composition information available for engineering review, viscosity with temperature and method where possible, and a description of foam, stringing, dripping, particles, abrasiveness, volatility and sensitivity to air or shear. State whether the product settles or changes during the shift. Honey, sauces, oils, detergents and solvents cannot be grouped safely by a marketing label alone.
Identify compatibility requirements for tubing, seals, pump parts, hoses and nozzles. If the liquid is corrosive, flammable, hazardous, sterile or used in a classified environment, a general product page is not sufficient. The destination’s safety, material and regulatory requirements need a separate technical review.
2. Peristaltic-pump filling questions
A peristaltic pump moves product by compressing flexible tubing. The tubing is a central product-contact and wear component, so buyers should confirm material compatibility, expected replacement conditions, internal diameter, installation method and the effect of tubing condition on calibration. Ask how the tube is primed, clamped and changed and whether the intended cleaning method uses replacement, flushing or another validated procedure.
The available dose and output depend on the selected pump head, tubing, product, number of heads and operating settings. Do not infer suitability for particles, solvents or high-temperature product from the pump name. A sample trial should record product temperature, tubing specification, settings, fill measurements and any dripping or air-bubble behavior.
3. Piston-filling questions
A piston filler draws a defined displacement into a cylinder and delivers it through a valve and nozzle path. This principle can be considered for many viscous products, but the cylinder range, valve geometry, seals, particles, feed conditions and cleaning access must match the application. Ask which cylinder and nozzle cover each dose and whether very different volumes require change parts.
Provide particle dimensions and concentration for sauces or suspensions. Confirm whether the valve path can pass the material without blockage or damage and how product settling is controlled. Review hopper feed, air removal, anti-drip control and the method for dismantling and inspecting contact parts. “Piston” alone is not evidence of food, sanitary or particulate suitability.
4. Magnetic-pump filling questions
A magnetic-drive pump transmits motion without a conventional shaft seal in the same form as some other pump designs, but the wetted materials and complete pump construction still determine chemical compatibility. Ask for the exact pump model, contact materials, permitted temperature and operating limits for the proposed liquid. Avoid dry running or other operation outside the supplier’s stated conditions.
Clarify whether the proposed machine controls filling by weight, time, flow or another feedback method. The pump name and the dosing method are separate facts. Verify priming, suction conditions, back pressure, hose routing, nozzle shutoff and residual-product handling with the actual installation plan.
5. Compare dose, accuracy and output correctly
List the minimum, normal and maximum dose and the required acceptance tolerance at each point. Define whether the result is measured by net weight, volume or another method. Use the same product, temperature, container, sample count and calculation when comparing systems. A catalogue percentage or gram value from different test conditions is not a fair comparison.
For output, count accepted filled containers under the complete operating cycle. Include container loading or indexing, nozzle movement, fill time, settling, cap transfer and operator work. Additional heads can change the result, but they also change the machine, controls, manifold, cleaning and line balance. Treat each head count as a named configuration.
6. Compare cleaning and changeover as processes
Draw the product-contact path from supply vessel to nozzle. Identify hoses, tubing, pump parts, cylinder, valves, manifolds and dead spaces. Define draining, product recovery, flushing, removal, cleaning verification and reassembly. For frequent recipe changes, record the number of parts, tools, replacement items and the risk of mixing old and new product.
The equipment supplier can describe access and materials, but the buyer remains responsible for a cleaning and validation process suitable for the product, hazards and local requirements. A short water rinse during demonstration does not establish production sanitation.
Compare MUJIU Equipment
The CSY-L13 page carries the peristaltic-pump intent, the CSY-L30 page carries the magnetic-pump intent, and the AT-NY-L2 page is an automatic viscous-liquid configuration. These pages are examples, not universal compatibility claims.
Use the liquid filling selection checklist and send MUJIU the material, container and target data for a configuration review.
A pump quotation comparison record
Ask each supplier to answer the same fields. A proposal with unanswered compatibility or test questions should remain open for review rather than receive an assumed pass.

External pump versus internal pump: ask about access, not just location
External mounting can make a component easier to see, but it does not by itself prove easy disassembly, safe cleaning or a suitable contact material. Request a configuration-specific image showing the complete pump and connections, plus instructions for safe isolation and removal. Confirm whether the supplied configuration actually permits the maintenance task you need; do not dismantle equipment from a marketing description.
Before comparing CSY-3200 controls or an alternative filler
A button interface and a touchscreen are control-interface distinctions. They do not independently establish a different pump, accepted-output rate, contact-material specification or weighing accuracy. Compare the exact quoted configuration and raw test evidence. For a buyer requesting 250–1,000 mL olive-oil fills, first define density at the test temperature, bottle geometry and the acceptance method; do not equate a gram-denominated catalogue range with millilitre capacity.
Complete the liquid product data sheet and use the accepted-output test ledger to compare suppliers on the same basis.
