China Chemical Resistant Diaphragm Pump Manufacturers, Suppliers, Factory

The Chemical Metering Pump is a positive displacement chemical dosing device with the ability to vary capacity manually or automatically as process conditions require. Approximately 90% of all pumps sold are transfer pumps, which are designed to move liquids from point A to point B. But Chemical Metering Pumps are specialty pumps: They’re designed for precision-injection of chemicals, acids, bases, corrosives or viscous liquids and slurries.

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 Pump's Stainless Steel Diaphragm Pump is carefully designed and constructed of stainless steel for superior corrosion resistance and durability. This means they can operate stably for a long time in various harsh environments. The Stainless Steel Diaphragm Pump can be used to handle a variety of environmentally friendly liquids, meeting environmental regulations while reducing energy consumption through pneumatic operation.

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

China Hot Sale Aluminum Air-Operated Diaphragm Pump Factory. Aluminium Alloy Air Operated Diaphragm Pump is a novel volumetric pump that uses compressed air as the power source to distribute air through the reciprocating motion of the air valve and drives the diaphragm to squeeze the conveying medium.

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.
