China Digital Metre 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.

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

The components that enable us to automatically maintain the right levels of pH and/or chlorine in our pool are the efficient and dependable commercial pool dosing pumps. The main function of these commercial pool dosing pumps is the dosage of liquids, such as chlorine or the pH to maintain the ideal level of these parameters in the water. Have a control and adjustment of these levels is essential to prevent problems such as irritation of the eyes or the appearance of algae in the pool. Discover all the metering pumps for pH and chlorine pools and find the most suitable for you.

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.

Our Metering Pump Check Valves For Industrial Applications​ products are recognized and praised by customers all over the world with excellent quality and good reputation!

Dongkai is a leading China Bladder-Operated Vibration Absorber manufacturers, suppliers and exporter. The Bladder-Operated Vibration Absorber 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.
