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.

Dongkai is a leading China Chemical Dosing Pump for Ammonia manufacturers. Chemical Dosing Pump for Ammonia'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 leading China Metering Pump for Accurate Acid Chemical Dosing manufacturers. The small solenoid diaphragm Metering Pump for Accurate Acid Chemical Dosing offer precise chemical injection at a low cost. The compact size and simple control make them ideal for water treatment and OEM applications.

Dongkai is a professional leader China Industrial piston pump manufacturers. A positive displacement pump in which the high-pressure seal reciprocates with the piston is called an industrial piston pump. Gases can be compressed and liquids moved using industrial piston pumps. They can function under a variety of pressure conditions. It is possible to operate at high pressure without significantly affecting flow rate. Solid particle and viscous media can also be handled by industrial piston pumps. This kind of pump works by means of a piston cup, oscillation mechanism, and filling of pump chambers through downstrokes that create pressure differentials and upstrokes that force the pump fluid out for use. Industrial piston pumps are frequently utilized in water delivery or irrigation systems and in situations where a high, steady pressure is required.
