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.

Type 02High-precision metering for low-to-medium flow rates. Electronically adjustable with manual, pulse, or 4–20 mA control — ideal for water treatment and pH correction.
View Models
Type 03Robust continuous-duty pumps for high-volume chemical dosing. Low pulsation, suitable for aggressive chemicals and demanding industrial environments.
View Models
Type 04Heavy-duty piston design for high-pressure applications requiring consistent, high-flow chemical injection in industrial processes.
View Models
Type 05Advanced digital control panel for precise dosing adjustments, real-time monitoring, and integration with plant automation systems.

A dosing pump head that fails on chemical contact rarely fails quietly. Seals swell or crack, valves stick, and the pump head itself eventually leaks, usually discovered as a puddle...
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...
Hard water is one of the most common reasons a Dosatron unit starts dosing inconsistently or stops working altogether. The mechanism is straightforward: calcium and magnesium carbonates precipitate out of...
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...
Most engineers size a metering pump based on two things: the required flow rate and the discharge pressure. These are the right starting points. But for viscous chemicals, there is...
If you run a machine shop, a CNC production line, or a tool and die operation in Malaysia, you have almost certainly faced this decision: what is the best way...
Chemical compatibility charts give you a starting point. They do not tell you whether your specific system will fail. The chart says EPDM is compatible with 30% sulphuric acid —...
Timer-based chemical dosing looks simple on paper: set a pump to run for a fixed period at fixed intervals, inject a known volume of chemical, move on. The problem is...
