Faqs

What are chemical injection pumps used for?

Chemical injection pumps are used to introduce chemicals into a process stream at high pressure, ensuring effective mixing and reaction. They are crucial in applications such as water treatment, oil and gas production, and chemical manufacturing as ingredients, for process control, as markers for traceability and to improve efficiency.

What types of pumps are suitable for chemical injection?

Suitable pumps include diaphragm (AODD), piston, peristaltic, screw and progressive cavity pumps. These pumps handle a range of chemical viscosities and pressures, ensuring precise dosing and reliability.

Which industries use chemical injection pumps?

Industries such as oil and gas, water treatment, pharmaceuticals, and food processing utilise these pumps for accurate chemical dosing, ensuring process control and safety.

How do I choose the right chemical injection pump?

Consider factors such as chemical concentration, compatibility, temperature, accuracy required, ability to control via simple dial or user interface, required flow rate, and pressure. Consulting North Ridge Pumps ensures expert advice tailored to your specific application needs, ensuring optimal pump selection.

Chemical Injection Pumps for Safe Mixing and Line Pressure Management

Chemical injection is the process whereby a chemical is pumped at a higher pressure than the current line pressure where the liquid is being introduced. Chemical injection pumps are specifically designed to pump at a pressure higher than the line pressure, ensuring the chemical can overcome the pressure in the line and mix effectively with the fluid being pumped. If the chemical were pumped at a lower pressure, siphoning could occur, causing improper mixing and potential system issues. These pumps are commonly used in industries like oil and gas, chemical manufacturing, and wastewater treatment, where precise chemical dosing and injection are critical to operational safety and efficiency.
