High precision and reliability Accurate Hydraulic Diaphragm Metering Pumps are highly precise and reliable metering pumps for chemical processes which achieve metering accuracy within ±1% (see Note 1), linearity within ±2% (see Note 3) and feature a driving unit specially designed for long-term continuous operation. Improved cost performance The mechanical efficiency of the reduction gear as well as that of the entire pump is improved. In addition, the employment of a large-capacity pump head and the standardization of high-speed types have further improved the cost efficiency of the pump. Compact and lightweight.

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

Auto Flocculant Dosing Systems 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 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 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.

Automatic dosing device is a device that often needs to continuously and automatically inject one liquid into another liquid to become a mixed liquid in the fields of electric power, water treatment and so on. The types of automatic dosing devices include double pump single control combined type, three pump double control combined type, etc. Next, we will introduce the relevant contents in detail.
