China Swimming Pool Equipment Metering Dosing Pump Manufacturers, Suppliers, Factory

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

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.

Find a huge selection of Industrial Flocculant Dosing System from China at Dongkai. The automatic Industrial Flocculant Dosing System (also called Polymer doser, polymer makeup system, polymer preparation unit, etc.) adopts the PLC control method, which pioneered the integration of fully automatic adjustment of pharmaceutical concentration, automatic dosing, dissolution, and dosing, achieving a breakthrough in continuous unmanned operation; significantly reducing the cost of design, construction, operation and maintenance.

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.

The Aluminum electric diaphragm pump is with the cycloidal reducer which can enable the volume of left and right pump chamber, it sucks and exhausts liquid in that principle. The pumps are widely applied in more and more industrialized countries over the world in recent years because of the breakthrough development in its diaphragm materials, it displaces some centrifugal pumps and screw pumps and is used in the fields of chemistry, ceramics, metallurgy and so on.

Stainless steel Electric diaphragm pumps combine the advantages of air-operated double diaphragm pumps with an energy efficient electric drive to reduce energy consumption, operating costs and pulsation. The centre section of these pumps use an electric drive instead of compressed air. The centre section is filled with pressurised air and is mechanically moved by the motor pushing and pulling the diaphragm from left to right. This back-and-forth motion, forces material out of one chamber and into the outlet manifold, whilst filling the opposite fluid chamber via the inlet manifold. The smooth changeover allows for reduced pulsation at the outlet.
