Introduction
A dosing pump, which is a positive displacement pump, is designed to inject a chemical or another substance into a flow of water, gas, or steam. Dosing pumps, which are typically small, provide an extremely precise flow rate for maximum control. They are the central part of an integrated dosing system designed for the automatic dispersion of chemicals. This dosing definition applies to a wide range of applications and industries, from wastewater treatment to food processing.
Features:
- Easy installation
- Available in multihead
- Dimensional accuracy

Parts of a Chemical Dosing System
The main components of a dosing pump include:
- Chemical Container or Tank – holds the product to be dosed.
- Pump – varies in materials and size; includes an inlet, suction line, and dosing line.
- Injector – one-way valve where the chemical is injected into product; overcomes pressure in the pipe and allows chemical into liquid flow.
- Foot Valve – one-way valve attached to the suction line; placed into product drum and keeps the pump primed.
- Dosing Line – rigid tube or reinforced hose; can be PE, PVC, or stainless steel for high-pressure use.
- Control System – Ensures accuracy; turns on and off at specific times. Can be a simple flow switch or timer, up to a SCADA central control system for various sensors, and the ability to integrate into a larger system.
