Moonshan Viscous Liquid Filling Machine 2-IN-1
The Moonshan Viscous Liquid Filling Machine combines two operating modes: weight-based filling and time-based filling, to accommodate viscous liquids such as oil, honey, gel, and sauces. It uses a stainless steel gear pump with a 1/2 gallon per minute capacity, offering strong suction for thick products. A three-stage filling speed and an anti-drip nozzle support precise filling, with a weighing scale delivering accuracy up to 1 gram. This model is suitable for lab-to-small-batch production where consistent viscosity handling and minimal drips are essential.
Key considerations:
– Suitable viscosity handling; anti-drip nozzle reduces waste.
– Dual modes provide flexible filling strategies for varying batch sizes.
– Stainless steel components help resist chemical exposure; verify compatibility with specific chemistries.
Typical applications include viscous oils, syrups, gels, honey, sauces, and some chemical concentrates used for testing or formulation work. Users should confirm compatibility with the exact chemical fluids in use and observe safety guidelines when handling reactive substances.
Moonshan 4 Head Thin Liquid Filling Machine
This model features four independent filling channels designed for thin liquids that require quick throughput and synchronized fills. It is ideal for filling low-viscosity products such as water-like chemical solutions, detergents, or cosmetic-grade liquids where rapid processing is beneficial. The unit emphasizes easy tube connections for clean transitions between channels and straightforward maintenance to minimize downtime.
Key considerations:
– Multiple independent channels reduce bottlenecks in small-batch production.
– Best suited for low-viscosity liquids; not recommended for thick pastes.
– Quick tubing connections facilitate cleaning and reconfiguration for different products.
Potential chemistries should be compatible with the materials in contact surfaces, especially if reactive or solvent-based fluids are used. Regular inspection of seals and nozzles helps maintain accuracy and prevent leaks.
[2025 New Version] Moonshan 2-300g
The upgraded Moonshan 2-300g weighing filling machine offers a three-mode operation (weight, time, and price-based control) with a digital control panel. It uses a hygienic peristaltic pump where the liquid only contacts the silicone tube, reducing contamination risk and simplifying maintenance. The device can fill bottles up to 300 g with quick tare and precise descent as it approaches the target volume, delivering reproducible results at higher speeds compared to basic gravity-fed systems.
Key considerations:
– Peristaltic pump minimizes liquid contact with moving parts, helpful for reactive fluids.
– Three modes provide versatile filling strategies for different process requirements.
– A short set-up time helps teams quickly switch between formulations.
Recommended for chemical formulations that require clean transfer, minimal exposure to pump components, and reliable repeatability across batches. Users should validate pump materials against their chemical compatibility chart and observe safe handling practices for volatile or reactive liquids.
Moonshan 2-118 Oz Bottle Filler Machine
This compact Moonshan model provides intelligent, precise quantification with a large flow-capable diaphragm pump. It supports up to 118 oz per minute and stores seven data groups for different filling settings. It is suitable for medium-volume production of cosmetic liquids, essential oils, beverages, and certain chemical solutions where a robust digital control system enhances repeatability and traceability of fills. An automatic counting feature speeds up smaller-batch workflows.
Key considerations:
– High flow rate supports medium-volume workloads.
– Data storage enables quick recall of previously used volumes for batch traceability.
– Diaphragm pump design offers clean liquid contact surfaces for easier sanitation and cleaning.
Ideal for chemical liquids that require dry-contact precision and repeatable volumes, while staying mindful of compatibility with diaphragm pump materials and seals for specific chemical classes.
VEVOR Pneumatic Paste Liquid Filling Machine
The VEVOR pneumatic paste filling machine uses a foot-pedal control to manage liquid dispensing, with a 5-50 ml range. It is built from 304 stainless steel and designed to withstand high temperatures up to 392°F (200°C), making it suitable for paste-like chemical liquids that require heat resistance during processing or clean-in-place routines. The unit emphasizes precise screw adjustments to set fill quantity and has a durability-focused design for repeated use in small to mid-scale operations.
Key considerations:
– Pneumatic operation allows hands-free filling while bottles are prepared.
– Food-grade stainless steel construction supports broad chemical compatibility and easy cleaning.
– Temperature tolerance supports a range of chemical liquids that may require sanitation or heat tolerance.
Best matched to labs or facilities handling chemical pastes, gels, or thick liquids where controlled, repeatable dosing is essential and where the tooling must tolerate occasional elevated temperatures or aggressive cleaning cycles. Always verify chemical compatibility with stainless steel and seal materials before use.
Buying Guide: Key Purchase Considerations And Comparisons
- Viscosity compatibility: Choose a model that explicitly supports the viscosity range of your chemical liquids, from thin to highly viscous pastes. For thick gels or honey-like substances, consider machines with high-powered pumps (gear or peristaltic) and anti-drip nozzles.
- Filling mode and control: Weighing, time-based, and programmable modes offer flexibility. Weighing modes deliver accuracy, while time-based modes support rapid throughput. Some units add price-based options for batch optimization.
- Materials and chemical compatibility: Stainless steel (304/316) bodies and wetted parts reduce corrosion risk. Confirm compatibility with the specific chemicals, solvents, and temperatures involved in your process.
- Cleaning and sanitation: Look for easy disassembly, smooth tubing connections, and pump designs that minimize residue. Diaphragm and peristaltic pumps are often favored for clean liquid handling.
- Throughput vs. precision: Higher flow rates can speed up production but may come at the expense of precision in some designs. Balance throughput with the needed accuracy for your application.
- Footprint and portability: If space is limited or if you need to reposition equipment, consider smaller benchtop models with clear access to control panels and hoses.
- Maintenance and spare parts: Check availability of replacement parts (nozzles, seals, diaphragms) and the ease of routine maintenance. Training or documentation may help operators maintain accuracy.
- Safety and compliance: For chemical use, ensure the device supports safe handling practices, and verify any regulatory or safety requirements relevant to your facility.
In summary, select a machine that aligns with your liquid properties, required fill accuracy, batch size, and cleaning protocols. For laboratories or small-scale production handling chemical liquids, models with robust stainless steel construction, anti-drip features, and versatile filling modes typically offer the best mix of reliability and versatility.
