China Pneumatic Pump Manufacturers, Suppliers, Factory

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

The Phosphate dosing device is a complete system for the elimination of phosphate, consisting of a storage tank dosing station and PROCON output control system. Access ladder and our platform are designed according to accident prevention regulations . Available as pre-assembled system or in components. Suitable for indoor or outdoor installation.

Dongkai is Chlorine Injection Pumps manufacturers and suppliers in China who can wholesale Chlorine Injection Pumps. 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 Chlorine Injection Pumps.

Hot selling quality Precision Diaphragm Chemical Pumps with High Hydraulic Flow Manufacturers and Suppliers. Precision Diaphragm Chemical Pumps with High Hydraulic Flow 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 Precision Diaphragm Chemical Pumps with High Hydraulic Flow effective for use with fluids that should not be exposed to outside air. Precision Diaphragm Chemical Pumps with High Hydraulic Flow 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, these Precision Diaphragm Chemical Pumps with High Hydraulic Flow offer higher accuracy and allow for high-pressure injection.

Dongkai is a leading China Chemical Dosing Pump for Ammonia manufacturers. Chemical Dosing Pump for Ammonia'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....
