China Nitrile Rubber Manufacturers, Suppliers, Factory

Dongkai is a leading China High-Performance Plastic Electric Diaphragm Pumps manufacturers. The High-Performance Plastic Electric Diaphragm Pumps is a new type of pumps. In recent years break-through progress has been made in the diaphragm material, so more and more industrialized countries in the world have adopted such a pump type to replace some centrifugal or screw pumps to be applied in such industries as petrochemicals, ceramics and metallurgy. Plastics Electric diaphragm pump are applicable for low pressure applications, namely the outlet pressure ≥3kgf/cm2.

Dongkai is a leading China Innovative PAM Injection Equipment manufacturers, suppliers and exporter. Innovative PAM Injection Equipment is a continuous polymer makeup and dosing equipment. The equipment can mix the polymer fully with high efficiency, and then the homogeneous activated polymer can be ready for further treatment. Widely applied as the supporting equipment of sludge dewatering equipment in municipal wastewater, slaughtering, chemical plant and etc.

Dongkai is a leading China Hypochlorite Dosing 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 Hypochlorite Dosing Pump. Acid Liquid Chemical Metering Dosing Pump

Dongkai is a leading China Cost-effective phosphate dosing pump manufacturers.

China Advanced Plastics Air-Operated Diaphragm Pump Manufacturers and Suppliers. The Plastic Air-Operated diaphragm pump is the third generation of pneumatic diaphragm pump developed by Dongkai. It has six advantages of reliable quality, long service life, low noise floor, low vibration, high lift, never crash, and fine workmanship.

Dongkai is a leading China Ammonia Doser manufacturers. Ammonia Doser's working Principle: The motor drives worm gear pair; through eccentric mechanism, rotary motion of the motor is transformed into reciprocation of slide bar. Reciprocating slide bar directly propels mechanical diaphragm to make cyclic deformation, so as to suck in and discharge the medium....
