China High Pressure Positon Plunger Metering Pump Mechanical Diaphragm Dosing Pump Manufacturers, Suppliers, Factory

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.

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

China hot selling Stainless Steel Air-Operated Diaphragm Pump Manufacturers and Suppliers.Our range of highly-polished, Stainless steel Air Operated diaphragm pump (304 or 316L) have been specifically developed for applications that demand the highest standards of hygiene and contamination control in a clean and sterile environment.

China quality Diaphragm Pulsation Damper Factory. Diaphragm Pulsation Damper:It contains a composite PTFE diaphragm that separates an inert pressurized gas (air or nitrogen) from the pumped liquid. The size diaphragm pulsation damper should be 10 times of each metering pump stroke capacity at least.

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.
