China Swimming Pool Dosing Pump Manufacturers, Suppliers, Factory

Dongkai quality Safety Relief Valve back Pressure Valve help to relieve excess pressure on the pump system or maintain pressure at a setted point. Safely relief valve is installed on the outlet pipeline of metering pump. When the system pressure becomes abnormal, safety relief valve protects metering pump from any damages. Back pressure valve shall be installed at the outlet of metering pump in order to reduce siphon and excess feeding, and ensure the metering accuracy of metering pump is not affected. When dosing point is lower than the outlet of metering. Each Valve is diaphragm type with 2-port design, which can be used both as safety relief and back pressure valve

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.

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 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 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.

Zhejiang dongkai pump's Corrosion-Resistant Electric Membrane Pump is designed specifically for handling corrosive liquids. They provide superior fluid control, ensuring your process is not compromised. These pumps are constructed from corrosion-resistant materials, such as ductile iron, to withstand a wide range of chemicals. They have excellent durability and provide long-term stable operation.
