China Positive displacement pump Manufacturers, Suppliers, Factory

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....

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.

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.

Hot selling quality Precision Diaphragm Chemical Pumps with High Hydraulic Flow Manufacturers and Suppliers. Precision Diaphragm Chemical Pumps with High Hydraulic Flow 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 Precision Diaphragm Chemical Pumps with High Hydraulic Flow effective for use with fluids that should not be exposed to outside air. Precision Diaphragm Chemical Pumps with High Hydraulic Flow 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, these Precision Diaphragm Chemical Pumps with High Hydraulic Flow offer higher accuracy and allow for high-pressure injection.

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