High Pressure Metering Pump's operating principle: Reciprocation of plunger drives hydraulic oil, and hydraulic oil drives the diaphragm to reciprocate, so as to suck in and discharge the medium.

PAM Dosing Systems is a continuous polymer makeup and dosing equipment. The equipment can mix the polymer fully with high efficiency, and then the homogeneous activated polymer can be ready for further treatment. Widely applied as the supporting equipment of sludge dewatering equipment in municipal wastewater, slaughtering, chemical plant and etc.

Advanced Dosing pumps for alkali made in China. Alkali dosing Pump is one kind of Mechanical Diaphragm Metering Pumps Are suitable for water treatment equipment and engineering, For Chemical Fluid. Dosing pumps for alkali are specialized equipment used in various industrial, water treatment and chemical processes to accurately add alkaline solutions or chemicals to the system.

Stainless steel Electric diaphragm pumps combine the advantages of air-operated double diaphragm pumps with an energy efficient electric drive to reduce energy consumption, operating costs and pulsation. The centre section of these pumps use an electric drive instead of compressed air. The centre section is filled with pressurised air and is mechanically moved by the motor pushing and pulling the diaphragm from left to right. This back-and-forth motion, forces material out of one chamber and into the outlet manifold, whilst filling the opposite fluid chamber via the inlet manifold. The smooth changeover allows for reduced pulsation at the outlet.

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

The bladder-type damper could be considered as the most traditional and widespread dampener, since it offers a great performance and is manufactured in a very wide range of sizes and building materials. Competitive in price, it is also easy to install. It is specially indicated for clean liquids without suspended solids and of low viscosity. It is manually adjustable and usually installed together with back pressure valves to guarantee the correct pressurisation of the air chamber in relation to the working pressure of the pump, being this assembly very common in diaphragm or piston metering pumps.
