| Crude Oil is Pump |
Introducion
Oil dispatch pumps are a vital part of the global oil industry. They are used to move oil from storage facilities to pipelines, and from pipelines to refineries. Oil dispatch pumps are essential for ensuring that oil is transported efficiently and safely.
There are many different types of oil dispatch pumps, each with its own specific applications. Some of the most common types of oil dispatch pumps include centrifugal pumps, reciprocating pumps, and positive displacement pumps.
Centrifugal pumps are the most common type of oil dispatch pump. They are typically used for large-volume applications, such as moving oil from storage tanks to pipelines. Reciprocating pumps are used for smaller-volume applications, such as moving oil from pipelines to refineries. Positive displacement pumps are used for applications where precise flow control is required.
Oil dispatch pumps are subject to a variety of different stresses, including high pressure, high temperature, and corrosive fluids. To ensure that oil dispatch pumps operate safely and reliably, they must be properly designed, manufactured, and maintained.
This low pressure based Crude Oil Dispatch Pump operates on the principle of rotary pump. Fueled by diesel, this pumping system has self priming type structure. Accessible in different sizes, this pump is suitable for transferring lube oil, fleet refuel and petrol chemicals. This system comprises of a rotor that has sliding vanes for drawing of liquid. Its internal by pass vale improves its transferring performance. Advanced features of this Crude Oil Dispatch Pump make it suitable for handling volatile as well as viscous fluids at less horse power. Relief valve of this pump helps it to avoid excess work pressure.
Crude oil is typically pumped using various types of centrifugal pumps or positive displacement pumps, depending on the specific requirements of the operation and the characteristics of the crude oil being transported.
- Centrifugal Pumps: Centrifugal pumps are commonly used for pumping large volumes of crude oil over relatively short distances, such as from storage tanks to loading terminals or between processing units within a refinery. These pumps work by converting rotational energy from a motor into kinetic energy to move the fluid. Centrifugal pumps are suitable for handling low to medium viscosity fluids and are known for their simplicity, reliability, and low maintenance requirements.
- Positive Displacement Pumps: Positive displacement pumps, such as screw pumps, gear pumps, or reciprocating pumps, are employed when pumping crude oil over longer distances or when higher pressures are required. Positive displacement pumps operate by trapping a fixed volume of fluid and then displacing it through the pump discharge. They are capable of handling higher viscosity fluids and providing more precise control over flow rates. However, positive displacement pumps often require more maintenance and are sensitive to changes in viscosity and pressure.
Both centrifugal pumps and positive displacement pumps have their advantages and limitations, and the selection of the appropriate pump type depends on factors such as the distance of transportation, flow rate requirements, viscosity of the crude oil, pressure conditions, and the overall design of the pumping system.
- Centrifugal pumps
 |
| Centrifugal pump |
The most prevalent kind of pump utilized in the oil and gas sector are centrifugal pumps. Centrifugal pumps suck fluid into the intake of the pump and propel it through the discharge section using centrifugal force created by the rotating of the pump impeller. The discharge flow control valve regulates the flow through the pump.
Low-viscosity liquids that demand high flow rates are typically transferred using single-stage centrifugal pumps. Usually, they function as a component of a larger pump system that also includes other centrifugal pumps, such as horizontal multistage pump units for shipping crude oil or water injection pumps for secondary oil and gas recovery.
Progressive cavity pumps are also considered constant flow pumps because at a given speed, the flow rate is relatively constant regardless of system pressure. Flow slippage is normal at high pressure. Relief valves are an essential part of any progressive cavity pump discharge piping system to prevent over pressure on the pump and piping system.
On the down side, diaphragm pumps are susceptible to 'winks' - conditions of low pressure inside the system that slow down pumping operation. Fortunately, winks can be fixed using a back-pressure regulator. For the same reason, they are not suitable for continuous or long-distance pumping operations as they do not generally meet the required high pressure conditions.
Diaphragm pumps are one of the most versatile types of oil and gas pumps in the industry and move fluid through positive displacement with a valve and diaphragm. The working principle of this pump is that a decrease in volume leads to an increase in pressure in the vacuum and vice versa.
Diaphragm pumps are suitable for high volume fluid transfer operations in oil refineries. Due to their fewer moving parts and less friction during operation, they require much less maintenance than positive displacement pumps and are available in compact designs.
Gear pumps are also widely used for chemical transfer applications for high viscosity fluids. There are two main variations: external gear pumps which use two external spur gears or timing gears that drive the internal gear set. The internal gears do not touch, so non-lubricating fluids can be pumped with external gear pumps. Internal gear pumps use a shaft driven drive gear to drive the internal mating gear. Gear pumps are positive displacement (or fixed displacement), meaning they pump a constant amount of fluid for each revolution.
A gear pump uses the meshing of gears to pump fluid by displacement. Gear pumps are one of the most common types of positive displacement pumps for transferring industrial fluids.
Since the pumped fluid passes between the close gear tolerances, gear pumps are normally used for clean fluids. A relief valve is an essential component in the discharge piping system to protect the pump and piping from over pressurizing.
A metering pump transfers a precise amount of liquid over a specified time period while providing a precise flow rate. The delivery of liquids in precisely adjustable flow rates is sometimes called metering. The term "metering pump" is based on the application or use, rather than the exact type of pump used. Most metering pumps are simplex reciprocating pumps with a packed plunger or diaphragm liquid end. The diaphragm liquid end is preferred because the pumped fluid is sealed inside the diaphragm. No pumped liquid seeps into the atmosphere.

- Reciprocating pumps

| Reciprocating pumps |
Reciprocating pumps are used to move smaller volumes of oil at lower speeds. Reciprocating pumps are typically used in applications where precise flow control is required, such as in refineries.Some of the most common industrial pumps in the oil and gas sector are plunger pumps. Plunger pumps pressurize a fluid in a piping system in an enclosed cylinder using the reciprocating motion of a plunger and piston. Because the flow rate is constant at a particular speed regardless of system pressure, plunger pumps are regarded as constant flow pumps. Any plunger pump discharge piping system must include a relief valve to prevent the pump and piping system from experiencing excessive pressure.its also knowan as a Positive displacement pumps and its used to move oil in a precise amount. Positive displacement pumps are typically used in applications where the volume of oil must be carefully controlled, such as in metering systems.
Here Some Other Oil Dispatch Pumps
- Progressive Cavity Pump

| Progressive cavity pump |
Progressive cavity pump is a type of positive displacement pump and is also known as eccentric screw pump or cavity pump. As its rotor is rotated, it moves fluid through a sequence of small, fixed-size, distinct cavities, progressing through the pump. Progressive cavity pumps are used in high viscosity applications or if mixing of the pumped fluid is not desired.

- Diaphragm Pump
One of the most adaptable types of oil and gas pumps available, diaphragm pumps use valves and diaphragms to transport fluid through positive displacement. This pump operates on the basis that a reduction in volume causes an increase in vacuum pressure, and vice versa.
For high volume fluid transfer activities in oil refineries, diaphragm pumps are suitable. They are available in smaller designs and require substantially less maintenance than positive displacement pumps since they have fewer moving parts and experience less friction during operation.
The drawback is that winks, or low pressure conditions inside the system, can cause diaphragm pumps to operate more slowly. Fortunately, using a back-pressure regulator will allow winks to be fixed.They are also unsuitable for long-distance or continuous pumping operations because they typically do not meet the necessary high pressure requirements.

- Gear Pumps
A gear pump pumps a fluid via displacement using the meshing of gears. One of the most popular forms of positive displacement pumps for moving industrial fluids is the gear pump.
In applications involving chemical transfer of highly viscous liquids, gear pumps are also frequently used. External gear pumps, which employ two external spur gears, and timing gears, which power an internal gear set, are the two basic varieties. An external gear pump can be used to pump non-lubricating fluids because the internal gears do not touch. The internal mating gear of internal gear pumps is driven by a shaft-driven driving gear. Positive displacement (also known as fixed displacement) gear pumps pump a fixed amount of fluid with each revolutionGear pumps are typically utilized for clean fluids because they pass through closely spaced gear tolerances. A relief valve is a crucial part of a discharge piping system because it guards against high pressure that could damage the pump and piping.

- Metering Pump
A metering pump accurately calculates the flow rate by moving a precise amount of liquid in a predetermined amount of time. Metering is the term used to describe the delivery of fluids at exact, controllable flow rates. Instead of referring to the specific type of pump utilized, the word "metering pump" refers to the application or use. The majority of metering pumps are simplex reciprocating pumps with a liquid end made of a packed plunger or a diaphragm. Since the pumped fluid is sealed inside the diaphragm, the liquid end with the diaphragm is favored. No liquid that is pumped leaks into the atmosphere.
