Rendering Pump
Jiangsu Stord Works Co., Ltd. is one of the most professional rendering pump manufacturers and suppliers in China. If you're going to wholesale rendering pump at competitive price, welcome to get quotation from our factory. Customized orders are welcome.

A rendering pump is industrial pumping equipment designed to transfer suitable materials generated during animal by-product rendering and related processing operations.
Depending on the application and pump configuration, the equipment may be used for:
Animal fat transfer
Fish oil transfer
Process liquid transfer
Cooked material transfer
Slurry transfer
Rendering by-product handling
Wastewater or process stream transfer
Storage tank circulation
Unlike standard clean-water pumps, rendering applications may involve high-viscosity materials, suspended solids, elevated temperatures, and corrosive or chemically demanding environments.
Therefore, an appropriate rendering plant pump should be selected according to the specific material and process stage.

How Does a Rendering Pump Work?
The working principle depends on the specific pump type and material being transferred.
A typical rendering process can be represented as:
Raw Material Receiving → Cooking → Separation / Pressing → Fat & Solid Processing → Drying → Storage
Pumps may be installed at different transfer points depending on the process configuration.
1. Material Inlet
The material enters the pump from an upstream vessel, cooker, separator, storage tank, or processing unit.
2. Material Transfer
The pumping mechanism moves the material through the pump chamber and connected pipeline.
3. Pressure Generation
The pump generates sufficient pressure to overcome pipeline resistance, elevation differences, and downstream equipment requirements.
4. Discharge
The material is delivered to the next processing stage, storage tank, separator, dryer, or other equipment.
For viscous fats and oils, pump selection should consider viscosity and temperature because these factors can significantly influence pumping performance.
What Materials Can a Rendering Pump Handle?
The suitable material range depends on the pump type, construction materials, sealing system, temperature, and solids content.
Potential applications include:
Animal Fat
Rendering plants commonly recover fats from animal by-products. A suitable pump can transfer heated or processed fat between equipment and storage systems.
Fish Oil
Fish rendering and fish meal plants may require pumps for fish oil transfer and circulation.
Rendering Liquids
Process liquids generated during cooking and separation can be transferred using appropriately configured equipment.
Slurries
Some rendering processes produce mixtures containing liquids and suspended solids. Pump selection should account for particle size and solids concentration.
By-Product Streams
Suitable pumps can be integrated into systems handling processed animal by-products and other recoverable materials.
Core Features of Rendering Pumps
Designed for Industrial Rendering Applications
Rendering pumps are selected according to the demanding conditions found in animal by-product processing and resource recovery.
Suitable for Viscous Materials
For applications involving animal fats, oils, and other viscous materials, the appropriate pump configuration can help maintain stable transfer performance.
High-Temperature Application Options
Rendering processes can involve elevated material temperatures. Pump construction and sealing components should therefore be selected according to the actual operating temperature.
Reduced Manual Material Handling
Automated transfer helps reduce manual handling and can improve production continuity.
Flexible Process Integration
The pump can be integrated with:
Cookers
Presses
Separators
Dryers
Storage tanks
Conveyors
Evaporators
Other process equipment

Application
Animal Rendering Plants
A rendering pump can be used in animal rendering plants for transferring suitable fats, oils, process liquids, and other materials.
Typical process:
Raw Material → Cooking → Separation → Fat Processing → Storage
Poultry Rendering
Poultry processing generates feathers, fat, bones, viscera, and other by-products. Appropriate transfer equipment can be integrated into poultry rendering systems.
Fish Rendering
tor
Fish processing plants generate heads, frames, viscera, trimmings, and fish oil. Rendering pumps can support material and oil transfer within suitable fish processing systems.
Meat and Bone Meal Production
Rendering plants producing meat and bone meal may integrate pumping and conveying equipment with cooking, pressing, drying, and grinding systems.
Fish Meal and Fish Oil Production
Pumps can support transfer of suitable process liquids and fish oil within integrated fish meal and fish oil production lines.
By-Product Recovery
Rendering converts animal by-products into valuable products such as:
Animal fat
Fish oil
Meat and bone meal
Fish meal
Protein-rich materials
Reliable transfer equipment contributes to efficient resource recovery.
