In 2025, the KBS Sugar Mill in Thailand
encountered a serious challenge in transferring A massecuite.
The existing transfer pump failed and could no longer operate reliably before the start of the crushing season.
A massecuite with a Brix of 90°–95° has an extremely high viscosity of up to
100,000 cP, and it also contains solid sugar crystals.
These characteristics caused frequent existing pump failures, high maintenance costs, and unstable production.
KBS Sugar Mill urgently needed a reliable
replacement pump that could handle high viscosity, crystal-containing sugar
paste and be installed before the production season.
Solution: Bonve Lobe Pump for A Massecuite Transfer
With extensive experience in sugar industry applications, Bonve Lobe Pump was selected to provide a customized solution for KBS Sugar Mill.
Based on the operating conditions of 90°–95° Brix A massecuite, and the required flow rate of 50 m³/h and discharge pressure of 15 bar,
We recommended the following solution:
Pump Model: 300BV12-200
Motor Power: 55 kW
Output Speed: 65–68
rpm
Drive: Large-size gear reducer for high
torque output
The low rotational speed combined with high
torque enables the pump to overcome high pipeline resistance during
long-distance transfer, while effectively protecting sugar crystals from
damage.
Why Bonve Lobe Pumps Are Ideal for A
Massecuite
Rotary lobe pumps offer several key
advantages in high Brix sugar paste applications:
1. Excellent Performance with High
Viscosity Media
Rotary lobe pumps maintain stable flow even
when handling viscosities up to 100,000 cP, making them ideal for thick A
massecuite.
2. Gentle Handling of Sugar Crystals
The low shear, low speed design prevents
crystal breakage, ensuring consistent sugar quality and downstream process
stability.
3. High Torque at Low Speed
With a heavy-duty gearbox and low RPM
operation, the pump delivers strong torque, allowing smooth start-up and
continuous operation under high load conditions.
4. Stable Flow and Pressure
The pump provides pulsation-free and stable
output, which is critical for continuous sugar production processes.
5. High Reliability and Low Failure Rate
Designed for harsh industrial environments,
rotary lobe pumps significantly reduce downtime and maintenance frequency
compared to conventional pump types.
Installation & Operation Results
The rotary lobe pump was successfully
installed and commissioned in October 2025.
During the December production season, the pump operated continuously and stably transferred A massecuite for KBS Sugar Mill.
The operational performance has been highly
satisfactory, meeting all flow, pressure, and reliability requirements.
