China DMA Automatic Diaphragm Metering Pump Manufacturers, Suppliers, Factory

Ammonia metering pumps are specialized equipment used in a variety of industrial and water treatment applications to accurately and safely introduce ammonia (NH3) into the system. Ammonia is commonly used in various processes for pH control, water disinfection and nitrogen nutrition supplementation. 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 Precision Hydraulic Diaphragm Metering Pumps manufacturers, suppliers and exporter. High precision and reliability Precision Hydraulic Diaphragm Metering Pumps are highly precise and reliable metering pumps for chemical processes which achieve metering accuracy within ±1% (see Note 1), linearity within ±2% (see Note 3) and feature a driving unit specially designed for long-term continuous operation. Improved cost performance The mechanical efficiency of the reduction gear as well as that of the entire pump is improved. In addition, the employment of a large-capacity pump head and the standardization of high-speed types have further improved the cost efficiency of the pump. Compact and lightweight.

Metering system Ammonia dosing devicefor the low-odour and safe handling of ammonia solution. For a stable pH value and reduced corrosion in the vapour system.

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

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 SODIUM HYPOCHLORITE PUMP. Acid Liquid Chemical Metering Dosing Pump

Dongkai is a leading China High-performance phosphate dosing pump manufacturers. The High-performance 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.
