Tank oil pump

Types of tank oil pumps

Tank oil pumps are employed in the transfer of oil and other petroleum products. They have several applications, including oil tank filling, oil tanker unloading, and oil product transfer in pipelines. Tank oil pumps are designed to handle various oil grades, including heavy and viscous oils. There are different types of tank oil pumps, and here are some of them:

• Centrifugal tank oil pumps

  Centrifugal tank oil pumps use the rotational energy of impellers to generate centrifugal force, which moves the fluid being pumped. The design of these oil pumps is simple, and they require low maintenance. They also have a smooth and continuous flow and high-speed operation. However, they have limitations, including being unsuitable for viscous fluids, and they require constant submersion.

• Positive displacement tank oil pumps

  Positive displacement oil pumps function by trapping a fixed volume of fluid and displacing it through the pump's outlet. The operation of these pumps is independent of fluid viscosity and has a steady flow rate. They are suitable for high-pressure applications. However, they also have disadvantages, such as the requirement of a pressure relief valve and maintenance of close tolerances.

• Submersible tank oil pumps

  Submersible oil pumps are located in the oil or fuel storage tank's water bottom. They are designed to push oil to the surface through the pipeline. These pumps are efficient and have a reduced risk of cavitation. They also take up less space and have a simple design. However, if there is a power failure, it can be challenging to retrieve the pump, and there is also a risk of corrosion.

• Solar-powered tank oil pumps

  Solar-powered tank oil pumps use solar energy to power them. They are environmentally friendly, have low operating costs, and are efficient in remote areas with less energy infrastructure. However, their efficiency is affected by sunlight availability and require high initial installation costs.

• Hand-operated tank oil pumps

  Hand-operated tank oil pumps are manually operated and use human power to function. They have simple designs and low maintenance requirements. They are also versatile and have low initial costs. However, they have limitations in high flow rates and require more labor.

Specification and maintenance of tank oil pump

Tank oil pump specifications vary, as manufacturers design different models for various applications. The following are common oil tank pump specifications.

• Flow Rate

  The flow rate refers to the amount of oil the pump transfers in a given period. The measurement is in liters per minute or gallons per minute. The flow rate should match the tank's and oil's requirements. A slow flow rate is ideal for delicate oils, while thicker oils need a faster flow rate.

• Power Supply

  Tank oil pumps use different power sources depending on the model. The common options include battery-operated pumps, electric-powered pumps, and solar-powered pumps. Each power supply option has its advantages. For instance, battery-operated pumps are portable and convenient in remote areas.

• Pressure

  Tank oil pumps have varying pressure ratings. The pressure pumps need to match the oil viscosity and the delivery distance. Higher pressure is required to transfer oil over long distances or vertical heights. The measurement of the pressure rating is in pounds per square inch (PSI).

• Temperature Control

  Some tank oil pumps have temperature control features. The temperature control feature is vital when pumping oils that need specific temperature ranges. The temperature control features include heaters, cooling systems, and temperature sensors.

• Material

  Tank oil pumps are made from different materials. The material affects the pump's durability and resistance to corrosion. Common materials include stainless steel, cast iron, and aluminum. Each material has unique properties suitable for specific oil types and environmental conditions.

• Viscosity

  Oil viscosity refers to the thickness of the oil. The measurement of viscosity is in centistokes (cSt). Tank oil pumps are designed to handle oils with specific viscosity ranges. The viscosity should be within the pump's limits to avoid damage and ensure efficient pumping.

• Noise Level

  The noise level of the tank pump may be a concern, especially in residential or quiet areas. Manufacturers specify the noise level of the pumps they produce. The measurement is in decibels (dB).

• Suction Lift

  Tank oil pumps have a suction lift specification that refers to the vertical distance the pump can draw oil from the tank. The suction lift measurement is in meters or feet. The suction lift limit should be adhered to to prevent pump damage and ensure efficient oil transfer.

Tank oil pump maintenance helps to ensure the longevity and optimal performance of the pump. Here are some practical tank oil pump maintenance tips.

• Follow the manufacturer's maintenance guidelines.
• Regularly inspect the pump for wear and tear.
• Keep the pump and its surrounding area clean and free of debris.
• Monitor the oil level in the tank to avoid running the pump dry.
• Check for leaks and address them immediately.
• Ensure proper alignment of pump components.
• Check the electrical connections and cables for damage.
• Perform regular flow rate tests to ensure consistent oil transfer.
• Monitor the pump pressure and address any fluctuations.
• Inspect and replace worn or damaged seals, valves, and gaskets.
• Lubricate moving parts of the pump as per the manufacturer's recommendations.
• Monitor the pump's temperature during operation and address any overheating issues.
• Calibrate the pump as per the manufacturer's specifications.
• Use genuine replacement parts for repairs and maintenance.
• Keep a maintenance log to track service history and maintenance activities.

How to choose tank oil pumps

Choosing the right oil tank pump requires careful consideration of various factors. Here are some of them:

• Flow Rate

  The flow rate of the pump should be considered. This is the amount of oil that the pump can move in a given time period. Depending on how quickly the oil needs to be transferred, choose a pump with a flow rate that meets the required standards.

• Tank Size and Capacity

  Consider the size and capacity of the oil storage tank. Make sure the pump is suitable for the tank size and can handle the required volume of oil without overloading or damaging the system.

• Viscosity of the Oil

  Take into account the viscosity of the oil being pumped. Thicker oils may require more powerful pumps to overcome resistance and ensure a smooth flow. Choose a pump designed for the specific type of oil being stored in the tank.

• Environmental Conditions

  Consider the environmental conditions where the oil tank and pump will be located. Extreme temperatures, humidity, or corrosive environments can affect the performance and durability of the pump. Select a pump constructed to withstand the specific environmental conditions of the installation area.

• Noise Levels

  If noise is a concern, consider the noise level of the oil tank pump. Some pumps are designed to operate quietly, minimizing noise during oil transfer operations.

• Power Supply

  Consider the available power supply for the oil tank pump. Ensure that the pump is compatible with the accessible power source, whether electrical, pneumatic, or other types.

How to DIY and Replace Tank Oil Pump

Most oil pumps are located inside the gas tank. This makes it difficult to access and repair. However, there are a few things that can be done before calling a professional. Firstly, check the oil level. If the oil level is low, refill it to see if the pump starts working.

Secondly, the dial gauge may be faulty. Users can try a different gauge to see if the reading changes. Thirdly, there may be a loose connection. Inspect the wiring and connectors for any signs of damage. If anything appears, re-connect it properly.

It is highly advisable not to attempt any further DIY repairs on the tank. DIY attempts can lead to more damage and potentially cause fire hazards. A qualified technician will be able to disassemble the oil tank and perform further diagnostics. They will also be able to identify any faulty parts and replace them accordingly.
