China Chemical injection pump Manufacturers, Suppliers, Factory

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

Dongkai is a leading China Hypo Chlorine 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 Hypo Chlorine Pump. Acid Liquid Chemical Metering Dosing Pump

Dongkai quality Safety Relief Valve back Pressure Valve 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

Dongkai is a professional leader China Positive displacement piston pump. A positive displacement piston pump is a particular kind of positive displacement pump in which the piston reciprocates with the high-pressure seal. Liquids can be moved and gases can be compressed using positive displacement piston pumps. They can operate over a wide range of pressures. High pressure operation can be achieved without a strong effect on flow rate. Positive displacement 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. Positive displacement piston pumps are often used in scenarios requiring high, consistent pressure and in water irrigation or delivery systems.

Ammonia Dosing Pump'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....
