Product overview
Selected around the complete duty.
Dosing pumps introduce a defined quantity of chemical into a process stream or vessel. Petrox selects the pump around the chemical, target dose, system back pressure, operating pattern and required level of automation.
Solutions can be supplied as standalone pumps with accessories or integrated into a complete chemical dosing package with tanks, agitators, valves, piping and controls.

Frequently asked questions
Practical answers before selection.
Are dosing pumps and metering pumps the same?
The terms are often used together. Metering pumps emphasize controlled accuracy, while dosing pumps describe the chemical-feed application.
Can the pump respond to process flow?
Yes. A suitable controller, VFD or automatic stroke-control arrangement can vary output from an external signal.
What accessories are normally required?
Typical accessories include calibration pots, strainers, relief valves, back-pressure valves, pulsation dampeners and injection fittings.
