Overview
Proposition 65 Warning

Diaphragm dosing pump is a precision metering device utilized for handling chemicals. It employs a flexible diaphragm instead of a piston to alter the pump chamber's volume. This diaphragm oscillates, resulting in the intake and discharge of liquid through the pump's inlet and outlet valves.

Tips: How to do maintenance on a diaphragm dosing pump?

Regular Inspection: Routinely check for leaks, loose fittings, and worn components. Ensure that the diaphragm is intact and free from damage.
Diaphragm Replacement: Diaphragms are wear-prone parts. Replace them according to the manufacturer's recommendations or if they show signs of wear or damage.
Valve Maintenance: Inspect valves for clogs, leaks, or corrosion. Clean or replace them as needed.
Seals and O-rings: Examine seals and O-rings for wear and tear. Lubricate them as suggested by the manufacturer, or replace them if damaged.
Suction and Discharge Lines: Clear any blockages in the lines to maintain consistent flow. Ensure that the lines are securely connected.
Pressure Relief Valve: Check and test the pressure relief valve to guarantee system safety.
Electrical Components: Inspect electrical connections and controls for proper functioning.
Chemical Compatibility: Ensure that the metering pump is compatible with the chemicals being used, and follow guidelines for chemical handling and safety.
Record Keeping: Maintain a maintenance log to track service dates, component replacements, and issues encountered.

Existing reviews of Chemical Diaphragm Dosing Pump, 500 L/h Flow

Precise solution for continuous dosing

We have been using the ATO diaphragm dosing pump in our water treatment system for several months, and it has performed very reliably. The 500 L/h flow rate is stable and accurate, allowing us to inject chemicals with excellent consistency even under relatively high pressure. The PVC pump head shows good chemical resistance, and the 380 V, 550 W motor provides strong and smooth operation without overheating. Installation was straightforward, and the pump runs with low vibration and minimal noise.
