How to choose a high viscosity pump for winter waste oil extraction

  In winter, due to the decrease in temperature, the viscosity of waste engine oil will significantly increase, which poses a challenge to the pumping work. Choosing a high viscosity pump suitable for winter work has become particularly important. The following suggestions can help you choose the appropriate high viscosity pump:

1. * * Consider the characteristics of the medium * *: Waste engine oil may have a very high viscosity at low temperatures, so the selected pump should be able to handle this high viscosity medium. Check the maximum allowable viscosity range of the pump to ensure it can handle the viscosity under extreme winter conditions.

2. Heating function: Some high viscosity pumps are equipped with built-in heaters or jacket designs, which can maintain a certain temperature inside the pump body, thereby reducing the viscosity of the medium and making pumping smoother. Consider whether these additional features are needed.

3. Pump type selection: Positive displacement pumps, such as gear pumps, screw pumps, or vane pumps, are very suitable for pumping high viscosity media due to their strong self-priming ability and ability to handle high viscosity fluids.

Among them, gear pumps are particularly popular due to their compact structure and high efficiency.

4. Wear and corrosion resistance: Waste engine oil may contain impurities and corrosive components. Choosing pump body materials with good wear and corrosion resistance, such as stainless steel, alloy steel, etc., can extend the service life of the pump.

5. * * Check gap design * *: High viscosity pumps should have a reasonable gap design, which can ensure pump efficiency, avoid excessive shear force damage to the medium, and prevent jamming.

6. * * Preheating System * *: If conditions permit, install an external preheating system such as a hot water bath, steam heater, etc. to preheat the waste engine oil, further reducing its viscosity and making it easier to pump.

7. * * Regular maintenance * *: Regardless of the type of pump, it is necessary to regularly clean the filter, replace worn parts, and ensure that the pump is in the best working condition.

8. * * Consult a professional * *: If you are unsure which pump is most suitable for your specific needs, it is best to consult with the technical team of the pump manufacturer or distributor, who can provide professional advice based on your specific situation.

9. Cost benefit ratio: Consider the balance between initial investment and long-term operating costs, including factors such as energy consumption, maintenance frequency, and expected lifespan.

Through the above measures, you can better choose a high viscosity pump suitable for pumping waste engine oil in winter, ensuring smooth pumping operations even under severe cold conditions.
