Features and Benefits
Adjustable Flow Rate Control
Designed with variable, adjustable flow rates (10–70L/min across SJB10 to SJB4000 models), this pump delivers precise chocolate mass transfer tailored to your production needs. Easily adjust output to match different batch sizes and production line requirements without compromising efficiency.
Double-Jacketed Insulation System
Equipped with a robust double-jacketed pump body to maintain consistent, stable temperatures during chocolate mass delivery. This thermal insulation preserves chocolate viscosity, prevents solidification and fat separation, and ensures uninterrupted flow for premium-quality results.
Versatile Production Line Integration
Engineered for seamless standalone use or integration with existing chocolate production lines (including tempering, enrobing, and moulding equipment). This versatility makes it ideal for both small-scale operations and large-scale automated manufacturing facilities.
Hygienic Food-Grade Construction
All product-contact components are crafted from food-grade SUS304 stainless steel with a smooth, seamless interior. The corrosion-resistant design ensures easy cleaning and sanitization, fully complying with global food safety standards for chocolate and confectionery production.
Robust & Reliable Motor Performance
Features high-performance motors (0.37kW to 2.2kW, depending on model) with continuous-duty operation, delivering powerful, consistent torque for efficient chocolate mass transfer. The durable motor design ensures reliable long-term performance with minimal downtime.
Compact & Cost-Effective Design
With a space-saving footprint and modular design, the SJB Series pump maximizes production floor efficiency while reducing upfront investment. Its low-maintenance operation and energy-efficient motors make it a practical, cost-effective solution for automated chocolate mass feeding.
How it works
Efficient Delivery Across Diverse Production Lines
A Chocolate Delivery Pump integrates seamlessly into various stages of a busy food production line, acting as the critical circulatory system of a confectionery plant. It plays an indispensable role in safely connecting holding tanks and tempering machines directly to enrobing stations and moulding equipment. Maintaining the exact product temperature during this confectionery mass transfer is absolutely vital. If the mass undergoes sudden cooling during transit, it can cause severe pipeline blockages, costly downtime, and product that fails to meet quality control standards.
To meet these demanding industry requirements, Shanghai Yucho Industrial leverages over 35 years of manufacturing experience to engineer advanced double-jacketed delivery systems that fit beautifully into both standalone and fully automated setups. These robust, heavy-duty systems are meticulously crafted from premium, food-grade SUS304 stainless steel. Using this specific high-quality material ensures a seamless, remarkably easy-to-clean interior that strictly complies with rigorous international food safety standards, all while significantly reducing overall operational costs and minimizing daily maintenance needs.
What is the SJB Series Chocolate Pump?
The Significance of Chocolate Pumps in Confectionery Processing
Difference Between Standard Pumps and the SJB Series Chocolate Pump
Traditional pumps often struggle with the unique challenges of chocolate processing, such as maintaining temperature and handling viscous materials. The SJB Series stands out with:
- Double-Jacketed Heating: Prevents cooling-related blockages.
- Gentle Handling: Protects the delicate structure of tempered chocolate.
- Versatility: Handles a wide range of materials, including inclusion-filled compounds.
These features make the SJB Series a superior choice for confectionery manufacturers seeking reliability and precision.
How the SJB Series Chocolate Delivery Pumps Work
The SJB Series operates using a rotary design within a heated, double-jacketed housing. Here’s how it works:
- Material Feeding: Liquid chocolate or cream enters the pump through a large inlet.
- Heat Preservation: Warm water circulates through the double jacket to maintain temperature.
- Mass Transfer: Rotors gently push the material forward, ensuring consistent flow.
- Output: The material is delivered to downstream equipment like moulding or enrobing systems.
- System Synchronization: Variable speed drives adjust flow rates based on production needs.
This process ensures that chocolate is transferred efficiently and without compromising quality.
Advantages of the SJB Series for Confectionery Manufacturers
The SJB Series Chocolate Delivery Pumps offer numerous benefits, including:
- Consistent Flow: Ensures uniform delivery of chocolate to production lines.
- Temperature Stability: Prevents blockages and maintains product quality.
- Versatility: Handles a wide range of materials, from molten chocolate to creams.
- Energy Efficiency: Reduces operational costs with optimized power usage.
- Easy Maintenance: Simplifies cleaning and reduces downtime.
These advantages make the SJB Series an essential tool for efficient and reliable chocolate processing.

FAQs
Q1. What is the maximum viscosity an SJB series pump can handle?
The SJB Series Chocolate Pumps are designed to handle high-viscosity materials up to 50,000 centipoise (cP). This makes them ideal for thick chocolate masses, creams, and fat-based fillings while maintaining stable flow and product quality.
Q2. Why does chocolate require a pump with a heating jacket?
Chocolate needs precise temperature control to stay fluid and avoid crystallization or solidification during transfer. The double-jacketed heating system circulates warm water around the pump housing, keeping chocolate at its ideal working temperature. This prevents pipeline blockages and ensures smooth, uninterrupted production.
Q3. How does an SJB pump differ from a standard centrifugal pump?
Unlike standard centrifugal pumps, which use high-speed impellers that can damage delicate chocolate, the SJB pump employs a gentle rotary lobe or gear mechanism. This design minimizes shear stress, preserves the crystal structure of tempered chocolate, and ensures consistent flow without aeration or cocoa butter separation.
Q4. Can the SJB pump run in reverse for pipe stripping?
Yes, SJB Series pumps can run in reverse. This function enables effective pipe stripping, removing residual chocolate from the pipeline to reduce waste and simplify cleaning.
Q5. Which seal material is best for high sugar content chocolate?
For high sugar content chocolate, food-grade EPDM or silicone seals are recommended. These materials offer excellent resistance to sugar abrasion and thermal cycling, ensuring long service life and strict food hygiene compliance.
Q6. How often should the rotors and seals be inspected?
Rotors and seals should be inspected every 500 operating hours, or at least monthly depending on production intensity. Regular inspections help detect wear early, maintain stable performance, and avoid unplanned downtime.
Q7. Is the SJB series compatible with variable frequency drives?
Yes, the SJB Series is fully compatible with variable frequency drives (VFDs). This allows dynamic adjustment of speed and flow rate for greater process control and smooth integration into automated production lines.
