Description

Rugged and Economical Packaging Solution for Specialized Industrial Liquids

Transfer Pump System for Viscous and Aggressive Products.

Volumetric-Gravity Filling Nozzle with Manual Control.

Heavy-Duty Mechanical Roller Conveyor.

Pneumatic Overhead Capping Head on Articulated Arm.

The R-400 Semi-Automatic Line is engineered for environments where reliability, ease of use, and resistance to harsh chemicals are more critical than ultra-high speed. This machine is the workhorse for specialized producers who need to package products that are viscous, prone to foaming, or chemically aggressive—substances that can challenge more delicate automated systems. Its semi-automatic design puts the operator in direct control of the filling cycle, making it ideal for smaller batch production, frequent product changeovers, or packaging containers of non-uniform size and shape. Built with heavy-duty components and a focus on easy maintenance, the R-400 thrives in workshops, automotive blending plants, and chemical formulation facilities across emerging markets. It provides a reliable, low-risk entry into professional packaging for growing businesses in the automotive, industrial, and chemical sectors.

Technical Specifications and Machine Configuration for Demanding Applications

• Machine Type: Semi-Automatic, Linear (Station-based) Filling and Capping Line.

• Primary Applications: Engine & Motor Oils, Gear Oils, Hydraulic Fluids, Industrial Lubricants, Denatured Alcohol, Solvents, Anti-Freeze, Windshield Washer Fluid, Concentrated Detergents, and Agricultural Chemicals.

• Operation Mode: Operator-assisted. The worker places the container, initiates the fill cycle, then positions it under the capper.

• Filling Technology: Volumetric-Gravity Dosing supported by a transfer pump. The pump moves product from a drum or bulk tank to the filling nozzle, where a mechanically or electronically timed valve ensures accurate volume discharge.

• Filling Nozzle: A single, durable filling spout. Optional immersion nozzle available to fill from the bottom up, minimizing air entrapment and foam generation in oily or surfactant-rich products.

• Capping System: Pneumatic overhead capping head mounted on a flexible articulated arm. The operator brings the head down onto the pre-placed cap, and a pneumatic trigger applies consistent sealing torque for screw caps or press-fit closures.

• Conveyance System: Mechanical roller conveyor (roller gang) made of powder-coated steel or chemical-resistant materials. Allows for easy manual movement of heavy, filled cans between stations.

• Construction: Framework and critical parts are built from carbon steel with chemical-resistant coating. Product contact parts can be specified in AISI 304 or 316 Stainless Steel, or specialized plastics for highly corrosive chemicals.

• Control: Simple push-button or foot-pedal operation. May include a basic timer or counter for fill control.

Component Breakdown: Pump, Filling, Conveyance, and Overhead Capping

1. Transfer Pump System for Viscous and Aggressive Products: This is not a precision dosing pump but a robust transfer or booster pump designed to handle viscous liquids like SAE 40 oil or abrasive suspensions. It ensures a consistent supply of product to the filling head, overcoming line resistance and maintaining a steady flow for accurate gravity-based timing. Pump material compatibility (cast iron, stainless steel, PTFE) can be selected based on the chemical nature of the product.
2. Volumetric-Gravity Filling Nozzle with Manual Control: The core of the machine’s accuracy. Product flows from the pump into a nozzle chamber. When the operator activates the cycle, a valve opens for a pre-set time, allowing a specific volume to drain into the container by gravity. This method is simple, easy to clean, and highly effective for a wide range of viscosities. The fill volume is adjusted by changing the timer setting.
3. Heavy-Duty Mechanical Roller Conveyor: Designed for stability and low effort. The roller gang provides a smooth, rolling surface that makes it easy for an operator to push heavy, liquid-filled cans (20-liter pails or 5-gallon jugs) from the filling station to the capping station and then to the discharge area without lifting. This ergonomic design reduces worker fatigue and risk of injury.
4. Pneumatic Overhead Capping Head on Articulated Arm: This design offers exceptional flexibility. The capping head is suspended from a counterbalanced arm, allowing the operator to easily position it over containers of different heights and sizes. The pneumatic drive provides a reliable, consistent sealing force. This system is ideal for low-to-medium speed operations where container placement may not be perfectly uniform.

Ideal Use Cases, Operational Benefits, and Target Market Advantages

The R-400 is the strategic choice for specific operational models:

• Small-Batch Lubricant Blenders and Oil Companies: Producing specialized or private-label motor oils for local markets.

• Industrial Chemical Formulators and Distributors: Packaging solvents, additives, or cleaning concentrates for resale.

• Automotive Workshops and Fleet Maintenance Centers: Doing in-house packaging of recycled or blended oils.

• Agricultural Co-operatives: Filling liquid fertilizers or agrochemicals.
  The key benefits are Low Capital Investment compared to full automation. Exceptional Flexibility for handling various container types and product formulas with minimal changeover. Rugged Simplicity means fewer electronic components to fail, easier repair, and lower skill requirements for operators. Enhanced Safety for operators through controlled, semi-automated handling of potentially hazardous chemicals, with minimized spillage and exposure.

Built for Durability and Supported for Global Operation

The R-400 is constructed for the real world. Its design philosophy prioritizes mechanical robustness over electronic complexity, ensuring it can withstand demanding shop-floor conditions in diverse climates. While it may not have the extensive certification list of a pharmaceutical line, it is built to fundamental safety standards. For global customers, its simplicity is its strength: it uses widely available industrial pneumatic components and motors, making long-term maintenance and spare parts sourcing straightforward anywhere. Our support focuses on providing clear mechanical manuals, diagrams for wear parts, and access to generic component specifications, empowering your local technicians to keep the line running for years with minimal external dependency. This makes the R-400 a supremely practical and sustainable choice for industrial businesses building self-reliant operations in regions like Africa, Southeast Asia, and Latin America.
