China Electric Membrane Pump Manufacturers, Suppliers, Factory

Dongkai is a leading China Industrial Chemical Dosing Systems 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. Rising mains, sewage manholes, and pump stations are the usual locations for these systems. On the other hand, they can be deployed anywhere that odor containment is needed.

Find a huge selection of Industrial Flocculant Dosing System from China at Dongkai. The automatic Industrial Flocculant Dosing System (also called Polymer doser, polymer makeup system, polymer preparation unit, etc.) adopts the PLC control method, which pioneered the integration of fully automatic adjustment of pharmaceutical concentration, automatic dosing, dissolution, and dosing, achieving a breakthrough in continuous unmanned operation; significantly reducing the cost of design, construction, operation and maintenance.

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

China Advanced Plastics Air-Operated Diaphragm Pump Manufacturers and Suppliers. The Plastic Air-Operated diaphragm pump is the third generation of pneumatic diaphragm pump developed by Dongkai. It has six advantages of reliable quality, long service life, low noise floor, low vibration, high lift, never crash, and fine workmanship.

Dongkai is a leading China Metering Pump for Accurate Acid Chemical Dosing manufacturers. The small solenoid diaphragm Metering Pump for Accurate Acid Chemical Dosing offer precise chemical injection at a low cost. The compact size and simple control make them ideal for water treatment and OEM applications.

Dongkai is a professional leader China High Performance Air Pulsation Control manufacturers with high quality and reasonable price. High Performance Air Pulsation Control: It is a empty container with pressure gauge on the top. It works by the air in the damper chamber. When the air in the damper is dissovled into the liquid, the efficency of the damper will be reduced. It is recommended to drain the liquid out of damper. The size High Performance Air Pulsation Control should be 26 times of each metering pump stroke capacity at least.
