A chemical feed pump, also known as a chemical dosing pump, is a compact positive displacement pump that injects a precise amount of chemical or other substance into water, gas, or steam. It is typically part of a chemical feed system that comprises a pump or multiple pumps, storage tank, pipes, and control panel.
What is pump meter?
A metering pump moves a precise volume of liquid in a specified time period providing an accurate volumetric flow rate. They are typically made to meter at flow rates which are practically constant (when averaged over time) within a wide range of discharge (outlet) pressure.
How does a chemical pump work?
A dosing pump draws a measured amount of liquid into its chamber and injects the chemical into a tank or pipe that contains the fluid that is being dosed. It’s powered by an electric motor or an air actuator and has a controller that turns the pump on and off and manages the flow rate.
What is chemical feed?
Chemical Feed Systems are designed for automated chemical injection into the chemical feed tank for wastewater treatment. In the dosing process, chemical reagents are added into a water stream at a precisely controlled rate with positive displacement metering pumps.
How many types of pump are there?
There are three basic types of pumps: positive-displacement, centrifugal and axial-flow pumps.
Which pumps are used in industry?
The main types of pumps used in the chemical industry are:
- Centrifugal pumps: These are the most common type of pumps used in the chemical industry.
- Positive displacement pumps: These are all types of rotary pumps and include gear, screw, rotary vane and piston pumps.
What are the types of pump?
There are three basic types of pumps: positive-displacement, centrifugal and axial-flow pumps….The positive-displacement principle applies in these pumps:
- Rotary lobe pump.
- Progressive cavity pump.
- Rotary gear pump.
- Piston pump.
- Diaphragm pump.
- Screw pump.
- Gear pump.
- Hydraulic pump.
What does GDP stand for in pumps?
Pump Priming in the Japanese Economy The goal was to increase the gross domestic product (GDP) of Japan by 0.7% by the end of the year 2016.
What is dosing unit?
13. Dosage unit means an individual dose of a poison for therapeutic use and includes a tablet, capsule, cachet, single dose powder or single dose sachet of powders or granules.
Which pumps are commonly used for chemical dosing?
Gear pumps, piston pumps, peristaltic pumps, and diaphragm type pumps are all available pumps to consider when injecting chemicals.
Do they put chemicals in milk?

What are chemical pumps used for?
Chemical Pumps. What is a chemical pump? Chemical pumps are used to transfer chemicals and are designed to be resistant to corrosive and abrasive industrial liquids such as fuel, paint, bleach, solvents, etc. Chemical pumps can be either centrifugal pump or a positive displacement pump depending on the specific application.
What is a chemical process pump?
Chemical Process Pump. Chemical process pump is an important device for handling of hazardous chemicals in industries. Whether conveyance or use in chemical reactions, chemical products need to be handled efficiently and with care in order to avoid any kind of damage or corrosion occurring at the working place.
What is a chemical feed pump system?
A Chemical feed system is installed for several reasons. One of the main purposes behind a chemical feed system is to raise or lower the pH in your water. The system measures the amount of water used and pumps sodium hydroxide or soda ash into your water at the necessary amount to ensure that the pH in your water is neutral.
What is a water meter pump?
Although metering pumps can pump water, they are often used to pump chemicals, solutions, or other liquids. Many metering pumps are rated to be able to pump into a high discharge pressure. They are typically made to meter at flow rates which are practically constant (when averaged over time) within a wide range of discharge (outlet) pressure.
