China Aluminum Alloy Diaphragm Pump Manufacturers, Suppliers, Factory

Find a huge selection of Motor Drive Diaphragm Metering Pump from China at Dongkai Pump.

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.

Dongkai is a professional leader China High Performance Air Pulsation Control manufacturers with high quality and reasonable price. High Performance Air Pulsation Control: 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 High Performance Air Pulsation Control should be 26 times of each metering pump stroke capacity at least.

The bladder-type 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 leading China Industrial phosphate dosing pump manufacturers. The Industrial phosphate dosing pump is a metering pump, the pump capacity of which can be precisely adjusted in 0.2% increments, either manually or optionally with an electric actuator or control drive. The pump can adjust to shifting metering tasks with speed and dependability thanks to the integrated controller.

Dongkai is a leading China Sodium Hypochlorite Metering Pumps manufacturers. By turning on and off, a solenoid propels the solenoid shaft forward and backward. The dosing head's diaphragm receives this stroke movement. During pumping, two check valves stop the feed chemical from flowing back. That's not all, though. The metering rate of sodium hypochlorite metering pumps can be precisely changed by adjusting the stroke length and stroke rate.
