Every stroke of an AODD pump delivers a discrete pulse of fluid. This is not a defect — it is the fundamental operating principle of any positive displacement pump. But...





Dosing pumps and auto dosing units for controlled chemical injection across various industries and applications.
Autoflo distributes a range of dosing technologies including water-powered dosing pumps, solenoid-driven diaphragm pumps, motor-driven diaphragm pumps, piston dosing pumps, digital dosing pumps, and auto dosing units. These products are selected for dosing accuracy, chemical compatibility, operating reliability, and ease of maintenance.
Multiple dosing technologies — water-powered, solenoid-driven, motor-driven, piston, digital, and peristaltic systems
Controlled chemical injection — suitable for proportional dosing, batch dosing, pH correction, and process chemical dosing
Flexible control options — manual adjustment, pulse input, timer control, digital interface, and 4–20 mA signal control
Local engineering support — technical selection, commissioning, and after-sales
Type 01No electricity nor any sensors or controller required for chemical dilution or proportional dosing.

Most farmers know when something is wrong with their crops. The leaves tell you. The soil colour tells you. The yield at harvest tells you. The problem is, by the...
A dosing pump’s displayed flow rate and its actual delivered flow rate are only guaranteed to match at the exact moment it was last calibrated. Backpressure changes as downstream valves...
In a wastewater treatment plant, a motor-driven dosing pump is commissioned, calibrated, and signed off. Six months later, the effluent discharge readings are inconsistent. The process team increases the chemical...
Not every chemical dosed at a wastewater treatment plant needs to run continuously. Shock disinfection, digester biocide addition, and sludge-conditioning polymer ahead of a scheduled dewatering run are all examples...
At a municipal wastewater treatment plant, the coagulant dosing pump was calibrated six weeks ago to match average dry-weather flow. When a storm event doubles the influent flow overnight, the...
Self-service laundry operators face a fundamental tension in their business model. The machine is provided, the water and electricity are provided, and the wash programme is provided. But in many...
When engineers select a Dosatron model, the first number they look at is the flow rate range. This makes sense — the Dosatron must be able to handle the volume...
In any process that requires mixing a concentrated chemical with water at a consistent ratio, the manual method has an inherent problem: it depends entirely on human accuracy, every single...
