China Ductile Iron Y Strainer Manufacturers, Suppliers, Factory

Dongkai is a leading China Ammonia dispensing pump manufacturers. Ammonia dispensing pump, which are reciprocating positive displacement pumps, provide the greatest possible metering accuracy. They set the standard for safety, reliability and efficiency, especially when it comes to pumping supercritical fluids.

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 is a leading China High-Precision Swimming Pool Dosing Pump manufacturers. The effective and reliable High-Precision Swimming Pool Dosing Pumps are the elements that allow us to maintain automatically a proper parameters of chlorine and/or pH in our pool. The main function of these High-Precision Swimming Pool Dosing Pump is the dosage of liquids, such as chlorine or the pH to maintain the ideal level of these parameters in the water. Have a control and adjustment of these levels is essential to prevent problems such as irritation of the eyes or the appearance of algae in the pool. Discover all the metering pumps for pH and chlorine pools and find the most suitable for you.

Air Pulsation Damper: 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 air pulsation damper should be 26 times of each metering pump stroke capacity at least.

Dongkai is a leading China Chemical Dosing Pumps manufacturers, suppliers and exporter. A chemical dosing system is a facility for automated injection of reagents into a wastewater network for the control of septicity and odour emissions. These systems are typically used at pump stations, sewer manholes, and rising mains. However, they can be installed any place where odour containment is required.
