China PVDF Pump Manufacturers, Suppliers, Factory

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.

Dongkai Pump's Stainless Steel Diaphragm Pump is carefully designed and constructed of stainless steel for superior corrosion resistance and durability. This means they can operate stably for a long time in various harsh environments. The Stainless Steel Diaphragm Pump can be used to handle a variety of environmentally friendly liquids, meeting environmental regulations while reducing energy consumption through pneumatic operation.

Dongkai quality Safety Relief Valve for Back Pressure 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

Find a huge selection of Plastic Air-Operated Double Diaphragm Pumps from China at Dongkai. The Plastic Air-Operated Double 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.

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.

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
