China Western Chemical Pump Manufacturers, Suppliers, Factory

Dongkai is a leading China Hypochlorite Dosing Pump manufacturers. 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 Hypochlorite Dosing Pump. Acid Liquid Chemical Metering Dosing Pump

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 Positive Displacement Metering Pump from China at Dongkai. Positive Displacement Metering Pump's operating principle: Reciprocation of plunger drives hydraulic oil, and hydraulic oil drives the diaphragm to reciprocate, so as to suck in and discharge the medium.

Dongkai is a leading China Ammonia dosing pumps manufacturers. Ammonia dosing pumps, which are reciprocating positive displacement pumps, provide the greatest possible metering accuracy. They set the standard for safety, reliability and efficiency, especially when it comes to pumping supercritical fluids.

A piston pump is a type of positive displacement pump where the high-pressure seal reciprocates with the piston. Piston pumps can be used to move liquids or compress gases. They can operate over a wide range of pressures. High pressure operation can be achieved without a strong effect on flow rate. Piston pumps can also deal with viscous media and media containing solid particles. This pump type functions through a piston cup, oscillation mechanism where down-strokes cause pressure differentials, filling of pump chambers, where up-stroke forces the pump fluid out for use. Piston pumps are often used in scenarios requiring high, consistent pressure and in water irrigation or delivery systems.

Advanced Dosing pumps for alkali made in China. Alkali dosing Pump is one kind of Mechanical Diaphragm Metering Pumps Are suitable for water treatment equipment and engineering, For Chemical Fluid. Dosing pumps for alkali are specialized equipment used in various industrial, water treatment and chemical processes to accurately add alkaline solutions or chemicals to the system.
