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

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.

The effective and reliable Swimming pool water treatment dosing pumps are the elements that allow us to maintain automatically a proper parameters of chlorine and/or pH in our pool. The main function of these Swimming pool water treatment dosing pumps is the dosage of liquids, such as chlorine or the pH to maintain the ideal level of these parameters in the water. Have a control and adjustment of these levels is essential to prevent problems such as irritation of the eyes or the appearance of algae in the pool. Discover all the metering pumps for pH and chlorine pools and find the most suitable for you.

Auto Flocculant Preparation for the liquid or powder polymer preparation, designed for homogeneity in flocculant concentration Optimized design to ensure the polymer goes through the maturation process using the smallest footprint Auto Flocculant Preparation is a compact unit that automatically feeds the process, as needed, using a regulated ultrasonic level switch.

Dongkai is Chlorine Injection Pumps manufacturers and suppliers in China who can wholesale Chlorine Injection Pumps. 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 Chlorine Injection Pumps.

Explosion-proof dosing device is a kind of explosion-proof special dosing equipment among dosing devices. It is mainly used for chemical dosing in explosion-proof fields such as bottom-hole mining, natural gas, petroleum and petrochemical, chemical industry, food, textile, semiconductor and microelectronics.
