China Auto-Dosing System Manufacturers, Suppliers, Factory

Dongkai quality Safety Relief Valve back Pressure Valve help to relieve excess pressure on the pump system or maintain pressure at a setted point. Safely relief valve is installed on the outlet pipeline of metering pump. When the system pressure becomes abnormal, safety relief valve protects metering pump from any damages. Back pressure valve shall be installed at the outlet of metering pump in order to reduce siphon and excess feeding, and ensure the metering accuracy of metering pump is not affected. When dosing point is lower than the outlet of metering. Each Valve is diaphragm type with 2-port design, which can be used both as safety relief and back pressure valve

Dongkai is a leading China Hypo Chlorine Pump manufacturers. A solenoid moves the solenoid shaft forwards and backwards by switching on and off. This stroke movement is transferred to the diaphragm in the dosing head. Two check valves prevent the feed chemical from flowing back during pumping. But that's not all. The stroke length and stroke rate can be precisely adjusted to alter the metering rate of Hypo Chlorine Pump. Acid Liquid Chemical Metering Dosing Pump

The Phosphate dosing pump is a metering pump, the pump capacity of which can be precisely adjusted in 0.2% increments, either manually or optionally with an electric actuator or control drive. The integrated controller allows the pump to adapt quickly and reliably to changing metering tasks.

Dongkai is a professional leader China Industrial Air Damping Systems manufacturers with high quality and reasonable price. Industrial Air Damping Systems : It is a empty container with pressure gauge on the top. It works by the air in the damper chamber. When the air in the damper is dissovled into the liquid, the efficency of the damper will be reduced. It is recommended to drain the liquid out of damper. The size Industrial Air Damping Systems should be 26 times of each metering pump stroke capacity at least.

The Chemical Metering Pump is a positive displacement chemical dosing device with the ability to vary capacity manually or automatically as process conditions require. Approximately 90% of all pumps sold are transfer pumps, which are designed to move liquids from point A to point B. But Chemical Metering Pumps are specialty pumps: They’re designed for precision-injection of chemicals, acids, bases, corrosives or viscous liquids and slurries.

Dongkai is a leading China High-performance phosphate dosing pump manufacturers. The High-performance phosphate dosing pump is a metering pump, the pump capacity of which can be precisely adjusted in 0.2% increments, either manually or optionally with an electric actuator or control drive. The integrated controller allows the pump to adapt quickly and reliably to changing metering tasks.
