How to Choose the Right Pump for Kerosene Extraction?

In industrial production, energy transportation, and other scenarios, kerosene extraction operations are quite common. Kerosene has special physical and chemical properties: it has moderate viscosity, is volatile, and has certain lubricity. These characteristics put forward special requirements for the pumps used for its extraction. Choosing the right pump can not only ensure extraction efficiency but also extend the service life of the equipment and reduce maintenance costs.

I. Core Requirements for Pumps in Kerosene Extraction

Although kerosene is not as strongly corrosive as strong acids and alkalis, it is highly volatile and may produce flammable vapors at high temperatures. Therefore, the sealing performance of the pump is the primary consideration to prevent safety hazards caused by kerosene leakage. At the same time, kerosene has a moderate viscosity, which requires the pump to have good suction performance and stable flow output. In addition, considering the lubricating properties of kerosene, the internal components of the pump should be able to adapt to its lubricating conditions to reduce wear.

II. Recommended Pump Types for Kerosene Extraction

(1) Gear Pumps

Gear pumps are one of the common choices for kerosene extraction. They transport liquid by generating suction and pressure through the rotation of a pair of intermeshing gears. They have a simple structure, small volume, and strong self-priming capacity, which can meet the extraction needs of kerosene under different working conditions. Gear pumps have good sealing performance, which can effectively prevent kerosene volatilization and leakage. At the same time, they have high working efficiency and are relatively easy to maintain.                                                                                         

(2) Vane Pumps

Vane pumps are composed of rotors, vanes, stators, and other components. They realize liquid transportation by the sliding of vanes in the rotor slots to change the working volume. They have uniform flow, stable operation, and low noise, making them suitable for kerosene extraction scenarios with certain requirements for the working environment. However, vane pumps have high requirements for the cleanliness of the oil, so attention should be paid to filtration during use.

(3) Screw Pumps

Screw pumps push liquid to flow through the rotation of screws, featuring large flow, stable pressure, and strong self-priming capacity. Their internal structure is compact with excellent sealing performance, which can well cope with the volatility of kerosene. Moreover, screw pumps have strong adaptability to media. Even if kerosene contains a small amount of impurities, they can work normally, making them suitable for kerosene extraction operations under some complex working conditions.

III. Considerations for Model Selection

When choosing a pump for kerosene extraction, in addition to considering the type of pump, it is necessary to match according to specific working parameters such as flow rate, head, and working temperature. At the same time, it is important to select a pump with appropriate materials. Usually, materials such as cast iron and cast steel can meet the requirements of kerosene extraction. In addition, regular maintenance of the pump, checking the condition of seals, bearings, and other components, can ensure its long-term stable operation.
