China Centrifugal Pump Manufacturers, Suppliers, Factory

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.

Hot selling quality High Performance Chemical Diaphragm Pumps with High Flow Capacity Manufacturers and Suppliers. High Performance Chemical Diaphragm Pumps with High Flow Capacity 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 Performance Chemical Diaphragm Pumps with High Flow Capacity effective for use with fluids that should not be exposed to outside air.

Dongkai is a leading China Sodium Hypochlorite Metering Pumps manufacturers. By turning on and off, a solenoid propels the solenoid shaft forward and backward. The dosing head's diaphragm receives this stroke movement. During pumping, two check valves stop the feed chemical from flowing back. That's not all, though. The metering rate of sodium hypochlorite metering pumps can be precisely changed by adjusting the stroke length and stroke rate.

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

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.

The Plastics Electric diaphragm pump is a new type of pumps. In recent years break-through progress has been made in the diaphragm material, so more and more industrialized countries in the world have adopted such a pump type to replace some centrifugal or screw pumps to be applied in such industries as petrochemicals, ceramics and metallurgy. Plastics Electric diaphragm pump are applicable for low pressure applications, namely the outlet pressure ≥3kgf/cm2.
