China Oil metering pump Manufacturers, Suppliers, Factory

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.

China hot selling Stainless Steel Air-Operated Diaphragm Pump Manufacturers and Suppliers.Our range of highly-polished, Stainless steel Air Operated diaphragm pump (304 or 316L) have been specifically developed for applications that demand the highest standards of hygiene and contamination control in a clean and sterile environment.

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

The effective and reliable Swimming Pool Equipment 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 Equipment Dosing Pumps is the dosage of liquids, such as chlorine or the pH to maintain the ideal level of these parameters in the water. It is imperative to regulate and adjust these levels to avoid issues like eye irritation or the growth of algae in the swimming pool. Learn about all the metering pumps available for pH and chlorine pools and select the one that works best for you.

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.

Dongkai is a leading China Flocculant Dosing System for Wastewater Treatment manufacturers, suppliers and exporter. The automatic Flocculant Dosing System for Wastewater Treatment (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.
