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.

Diaphragm Pulsation Damper:It contains a composite PTFE diaphragm that separates an inert pressurized gas (air or nitrogen) from the pumped liquid. The size diaphragm pulsation damper should be 10 times of each metering pump stroke capacity at least.
Read MoreSend InquiryAir Pulsation Damper: It is a empty container with pressure gauge on the top. It works by the air in the damper chamber. When the air in the damper is dissovled into the liquid, the efficency of the damper will be reduced. It is recommended to drain the liquid out of damper. The size air pulsation damper should be 26 times of each metering pump stroke capacity at least.

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
