Chemical injectors are developed to boost the efficiency of well production pipeline flow and decrease corrosion. They function under certain conditions of fluid and chemical.

What are Chemical Injection Pumps employed for use in the Oil & Gas Industry?

What is Chemical Injection Pumps?

Upstream, Midstream, and Downstream oil & gas engineering company constantly seek to increase production capabilities, enhance production processes, guarantee that their infrastructure is protected and minimize time to shut down.

The most efficient method involves injecting chemicals in processes to boost the production capacity, reduce corrosion, prevent deposits and improve the reliability of the process.

An injection chemical pump releases measured amounts of fluid and then overpowers the pressure of the line. It is not just pumping the fluid into tanks but dispensing a pressured amount at a specific amount. Its performance is greatly affected by backpressure. Moreover, the flow rate must be maintained because it mixes a chemical with water as it travels across the pipe.

The use of chemical injection pumps within the Oil & Gas Industry

Chemical injection systems that make use of pumps have proven to be essential to increase profits through many of elements.

First, they use hydration inhibition in order to prevent freezing in the production line, which allows for the dispersal of crude water/gas. They remove the wax, salt, and other minerals that cause a reduction in production and prevents corrosion.

Chemical injection technologies are used in many Enhanced Oil Recovery applications onshore and offshore.

These injects are viscosity boosters to increase the speed of sweep through reservoirs, which improves the production of oil and gas. These Chemical Injection Packages are generally placed near water injection locations.

The advantages of Chemical injection systems within the Oil & Gas Industry –

  • Cost-effectiveness
  • Portability
  • Safety shutdown and instrumentation valves are designed to prevent injury to the operator and machines.
  • Reducing downtimes for repairs
  • Safe deployment in hazardous environments
  • Installation and maintenance is simple.
  • Oilfield chemical injection pumps

Chemical injection Systems are utilized in the oilfield to inject special chemicals to the production process at specific quantities.

The procedure of getting chemicals safely and efficiently within the production process or in the pipeline is vital for any chemical treatment program.

There are various kinds that chemical pumps are utilized in the oilfield, some of which operate mechanically that are driven via direct linkage to an electric pumping unit , and others can be operated by compressed field gases, air or an electric motor.

Most pumps utilize the piston with positive displacement (plunger) or diaphragm for metering the dose of the chemical. The volume of the chemical can be controlled by altering your plunger’s length as well as its strokes/minute as well as the size of the plunger.


Some pumps can come with dual heads that can pump two different chemicals at once. The location on the field, the power source available, and the necessary injection pressures typically determine the type of pump that is required.
