China Concentrated Sulfuric Acid Manufacturers, Suppliers, Factory

Dongkai is a leading China Sodium Hypochlorite Metering Pumps manufacturers. By turning on and off, a solenoid propels the solenoid shaft forward and backward. The dosing head's diaphragm receives this stroke movement. During pumping, two check valves stop the feed chemical from flowing back. That's not all, though. The metering rate of sodium hypochlorite metering pumps can be precisely changed by adjusting the stroke length and stroke rate.

Dongkai Pump's Water Quality Improvement System undergoes strict testing and quality control to ensure your water quality is hygienic and safe. It also has multiple layers of security to ensure the quality of the water is not contaminated. At the same time ,Rich experience QA can help you audit the factory or check the goods quality before shipping.

Dongkai is a leading China Digitally Controlled Diaphragm Pumps manufacturers, suppliers and exporter. Dongkai JXM/JZM Series Digitally Controlled Diaphragm Pumps Are suitable for water treatment equipment

Hot selling quality High Flow Hydraulic diaphragm Chemical Pumps Manufacturers and Suppliers. High Flow Hydraulic diaphragm Chemical Pumps that transmits power using operating oil (silicone oil, etc.) filled between a diaphragm and a piston that serves as the drive source. A built-in relief (safety) mechanism eliminates the need for relief valves and other devices for handling abnormal pressure, making High Flow Hydraulic diaphragm Chemical Pumps effective for use with fluids that should not be exposed to outside air. High Flow Hydraulic diaphragm Chemical Pumps also limit changes in discharge volume due to pressure fluctuations at the injection site, and are commonly used in high-pressure lines such as in petrochemical processes. Compared with direct-driven diaphragm pumps, theseHigh Flow Hydraulic diaphragm Chemical Pumps offer higher accuracy and allow for high-pressure injection.

Dongkai is a leading China Chemical Dosing Pump for Acid Liquids manufacturers. The small solenoid diaphragm Chemical Dosing Pump for Acid Liquids offer precise chemical injection at a low cost. The compact size and simple control make them ideal for water treatment and OEM applications.
