China High Flow Water Diaphragm Pumps Manufacturers, Suppliers, Factory

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!

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.

Dongkai is a leading China Chemical Dosing Pumps manufacturers, suppliers and exporter. A chemical dosing system is a facility for automated injection of reagents into a wastewater network for the control of septicity and odour emissions. These systems are typically used at pump stations, sewer manholes, and rising mains. However, they can be installed any place where odour containment is required.

Dongkai Pump's Liquid Dosage Control System undergoes rigorous testing and quality control to ensure safe and reliable operation. It also features multiple layers of safety protection to ensure the safety of operators and the environment.

Find a huge selection of Automatic ammonia dosing system from China at Dongkai. Automatic ammonia dosing system, which are reciprocating positive displacement pumps, provide the greatest possible metering accuracy. In particular, they establish the benchmark for efficiency, dependability, and safety when it comes to pumping supercritical fluids.

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.
