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.

AODD pumps and diaphragm dosing pumps deliver flow in discrete slugs — one slug per stroke, twice per revolution. The flow is not continuous; it is a series of pressure...
A coagulant dosing pump at a wastewater treatment plant is set to 45 L/h based on the average flow the plant sees on a normal day. At 6 a.m., as...
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...
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...
The Dosatron’s technical documentation is consistent on one point: dosing accuracy is maintained independently of variations in flow rate, water pressure, inlet height, and temperature. These are real advantages over...
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 —...
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...
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...
