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.

The Aluminum electric diaphragm pump is with the cycloidal reducer which can enable the volume of left and right pump chamber, it sucks and exhausts liquid in that principle. The pumps are widely applied in more and more industrialized countries over the world in recent years because of the breakthrough development in its diaphragm materials, it displaces some centrifugal pumps and screw pumps and is used in the fields of chemistry, ceramics, metallurgy and so on.

The effective and reliable swimming pool metering dosing pumps are the elements that allow us to maintain automatically a proper parameters of chlorine and/or pH in our pool. The main function of these swimming pool metering 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 leading China Ammonia Doser manufacturers. Ammonia Doser's working Principle: The motor drives worm gear pair; through eccentric mechanism, rotary motion of the motor is transformed into reciprocation of slide bar. Reciprocating slide bar directly propels mechanical diaphragm to make cyclic deformation, so as to suck in and discharge the medium....

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.

The 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 integrated controller allows the pump to adapt quickly and reliably to changing metering tasks.
