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...





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.

Walk into almost any poultry or swine house in Malaysia and you will find the same setup: a header tank sitting above the waterline, filled with a pre-mixed batch of...
A discharge sample comes back out of specification. The obvious first question, what was the dosing pump actually doing at the time, is often the hardest one to answer. If...
The Dosatron product range includes models with standard internal injection and models with external injection, designated IE. To most buyers, this looks like a minor configuration option. In some applications...
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 —...
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...
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...
Most pulsation dampeners are selected by volume — the engineer picks a 1-litre or 2-litre unit based on pump flow rate and calls it done. The dampener is installed, the...
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...
