echnical Highlights of KOLEBURG Pumps
Clogging Prevention & Reliability
Technical highlight of KOLEBURG: Unique pump impeller design
Unique Rotating Centrifugal Impeller
A large channel diameter will prevent it from becoming blocked.
Spiral centrifugal pumps have excellent anti-clogging properties. Their open, large-diameter channels provide high efficiency and anti-clogging properties, making it easy to transport bulk solids and long-fiber materials.
The spiral section produces a spiral propulsion effect, and the blade edge of the impeller is sickle-shaped. The replenishment of the blades gradually increases along the wheel direction, guiding the liquid flow and pipe objects to move near the axis. Additionally, the spiral action propels them along the collection into the centrifugal section while providing superior suction capabilities and reduced cavitation.

FAQ about animal glue pumps KOLEBURG recommends animal glue pumps for you
What is an Animal Glue Transfer Pump?
An animal glue transfer pump is a specialized conveying device tailored to the unique characteristics of animal glue production media, such as high viscosity, high temperature, and solid particle content (e.g., bone meal, skin residue). Different from conventional fluid pumps, it adopts optimized impeller structures (e.g., spiral design) and widened flow channels to prevent clogging by solid particles. Meanwhile, it uses high-temperature and corrosion-resistant materials to adapt to the harsh operating environment of animal glue extraction (60-120℃) and acid-alkaline cleaning processes.
In animal glue production, animal glue transfer pumps must meet three core requirements: first, excellent high-viscosity medium conveying capacity, which can stably transport animal glue liquid with a viscosity ranging from 10,000 to 1,000,000 CPS; second, strict food-grade hygiene compliance, ensuring that media-contact materials meet standards such as FDA 21 CFR Part 177 to avoid contaminating the final product; third, strong wear and corrosion resistance, adapting to the abrasion of solid particles in bone meal/skin residue slurry and the corrosion of acid-alkaline cleaning agents. The reliability of animal glue transfer pumps directly determines the continuity of production lines and the stability of product quality.
What Operating Conditions Determine Pump Selection in Animal Glue Production?
Accurately grasping operating conditions is the premise for selecting suitable pumps (including animal glue transfer pumps) in animal glue production. The following table lists the core operating parameters that need to be clarified, along with their impacts on pump selection, providing a scientific basis for pump type matching.
Operating Parameter | Animal Glue Production-Specific Details | Impact on Pump Selection |
|---|---|---|
Medium Type | Animal glue liquid, bone meal/skin residue slurry, acid-alkaline cleaning solution, steam condensate | Determines hygiene level, anti-clogging, wear resistance, and corrosion resistance requirements |
Solid Content (%) | 15-30% (bone meal/skin residue slurry in raw material pretreatment) | High solid content requires pumps with anti-clogging flow channels and wear-resistant impellers |
Maximum Particle Size (mm) | 1.0-3.0mm (crushed bone meal, undissolved skin residue) | Ensures solid particles pass smoothly without jamming or damaging pump components |
Temperature (℃) | 65-120℃ (glue extraction process), 80-90℃ (hot cleaning water), 90-110℃ (steam condensate) | Guides the selection of high-temperature resistant seals and heat-stable materials |
pH Value | 4.0-6.0 (animal glue liquid), 2.0-3.0/11.0-12.0 (acid-alkaline cleaning solution) | Determines the corrosion resistance grade of pump contact materials; acid-alkaline media require stainless steel or alloy materials |
Viscosity (CPS) | 10,000-1,000,000 (animal glue liquid in different production stages) | Affects pump head and efficiency; high viscosity requires impeller blade optimization |
Operation Mode | Continuous (large-scale factories, 24h/365); intermittent (small-scale traditional workshops) | Influences pump fatigue resistance, service life design, and energy-saving frequency conversion configuration |
Installation Method | Dry type / Submersible type / Vertical type / Horizontal type / Belt-driven type (based on workshop layout) | Determines pump structural type and installation dimension matching; dry type preferred for clean production areas |

How to Ensure Long-Term Stable Operation of Animal Glue Production Pumps?
Scientific operation and maintenance are crucial for extending pump service life, ensuring product quality, and reducing production costs. Combined with the characteristics of animal glue production (high viscosity, high temperature, complex media), the following targeted management strategies are proposed:
1. Key Points of Daily Inspection and Monitoring
- Real-time monitor pump flow, head, motor current, and medium temperature; install intelligent sensors for abnormal alarms (over-temperature, over-current, leakage)
- Check for media leakage at seals and flanges; stop the machine immediately for maintenance if leakage occurs to avoid product contamination
- Regularly clean the pump inlet filter screen to prevent blockage by bone meal and skin residue, which may affect suction efficiency
- Monitor pump noise and vibration; abnormal noise or excessive vibration may indicate impeller blockage or bearing wear
