China Oil Pump Manufacturers, Suppliers, Factory

Dongkai is a leading China Ammonia dispensing pump manufacturers. Ammonia dispensing pump, 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.

Dongkai is a professional leader China Bladder-Type Dampening Device manufacturers with high quality and reasonable price. The Bladder-Type Dampening Device 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 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. Nodular castiron Air-Operated diaphragm pump

Dongkai JXM/JZM Series Digital Auto Control Mechanical Diaphragm Metering Pumps Are suitable for water treatment equipment

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.
