China Western Chemical Pump Manufacturers, Suppliers, Factory

Dongkai is a leading China Ammonia dosing pumps manufacturers. Ammonia dosing pumps, 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.

Robust and reliable PAC dosing pump, as the special pump in the industry, even this is a small part in the dosing system, but this has been treated as the most important and haert part in a system. The PAC dosing pump with the quantitative dosing to achieve the system's dosing function. So nowadays, more and more Sewage Treatment need the PAC dosing pump for the intelligent & integrative operation. Designed with utmost precision, Dongkai PAC dosing pumps are in conformation with the high standards of quality. Our PAC dosing pumps are reliable in terms of longer life and precise performance. Along with this, our pumps stand tall on grounds of low operating cost.

Dongkai is a leading China Flocculant Dosing System for Wastewater Treatment manufacturers, suppliers and exporter. The automatic Flocculant Dosing System for Wastewater Treatment (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.

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 professional leader China Bladder-Actuated Damper manufacturers with high quality and reasonable price. The Bladder-Actuated Damper could be considered as the most traditional and widespread dampener, since it offers a great performance and is manufactured in a very wide range of sizes and building materials. Competitive in price, it is also easy to install. It is specially indicated for clean liquids without suspended solids and of low viscosity. It is manually adjustable and usually installed together with back pressure valves to guarantee the correct pressurisation of the air chamber in relation to the working pressure of the pump, being this assembly very common in diaphragm or piston metering pumps.

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.
