Soybean Oil Gear Metering Pump

 

Feasibility Analysis of Soybean Oil KCB33.3 Gear Metering Pump

 

I. Core Parameter Matching Analysis

 

Flow Rate and Pressure: The original pump (BFC50-AEKV6G2.2-300) requires a flow rate of 2 m³/h and a pressure of 10 bar. The KCB33.3 fully matches these two key indicators, ensuring stable system operation.

 

Media Compatibility: Soybean oil has a density of 0.919~0.925 kg/dm³. The KCB33.3 clearly states that it is suitable for soybean oil, and no special restrictions are mentioned for the sealing material (mechanical seal). It is compatible with fluids within this density range by default, with a low risk of leakage.

 

Power and Motor: The original pump has a motor power of 2.2 kW. The KCB33.3 is equipped with a motor of the same power (2.2 kW-4P). Although the number of poles differs (6 poles for the original pump vs. 4 poles for the KCB33.3), the power is the same and can meet the load requirements.

 

The AC380V power supply is compatible with the original pump's 230/400V. In industrial settings, 380V is a common three-phase power supply, requiring no additional adjustment.

 

II. Comparison of Structural and Functional Details

 

**Pump Body Material:** Both are made of cast iron (HT200), offering moderate corrosion resistance, suitable for conveying non-corrosive media such as vegetable oils, resulting in low long-term operating costs.

 

**Sealing Method:** The original pump uses a SiC/graphite/Viton mechanical seal. The KCB33.3 does not specify the sealing material but is labeled "mechanical seal."

 

**Recommendation:** Confirm whether the KCB33.3 seal material contains fluororubber (Viton) or an equivalent material to ensure chemical stability with soybean oil. If the materials are compatible, the sealing performance should meet the requirements.

 

**Safety Protection:** Both are equipped with an overflow valve to prevent system overpressure and ensure equipment safety.

 

**Connection Method:** The original pump uses a 1-inch BSP thread, while the KCB33.3 uses a 20/20 thread (possibly referring to a G1 thread).

 

Solution: Connection can be achieved via an adapter (such as a BSP to G thread adapter), which is low-cost and easy to operate.

 

III. Potential Advantages and Precautions

 

Advantages: Cost-effectiveness: The KCB33.3 has high parameter matching; if its price is lower than the original pump, procurement costs can be reduced.

 

Delivery Time: If the original pump model is scarce, the KCB33.3, as a common industrial pump, may have a shorter delivery time.

 

Maintenance Ease: Standardized design makes spare parts replacement and maintenance easier.

 

Precautions: Sealing Material Confirmation: It is essential to verify whether the KCB33.3 sealing material is resistant to soybean oil to avoid seal failure after long-term use.

 

Thread Compatibility: Prepare adapters in advance to avoid installation delays.

 

Noise and Vibration: The speed of the 4-pole motor may be higher than that of the original pump's 6-pole motor; the impact on the system needs to be assessed (e.g., whether vibration damping measures are required).

 

IV. Conclusion: The KCB33.3 gear pump can replace the original pump in soybean oil metering systems. Its core parameters such as flow rate, pressure, and power are fully matched, and the pump body material and safety functions also meet the requirements. It is crucial to confirm the compatibility of the sealing material and the threaded connection method to ensure there is no risk of leakage. If the above conditions are met, the KCB33.3 is a more cost-effective choice.
