Back pressure valves, diaphragms, pulsation dampeners, Y-strainers
When metering pumps operate under low system pressure, PVC back pressure valves, PVC safety valves, metering pump diaphragms, PVC pulsation dampeners, and Y-strainers may cause over-delivery, affecting metering accuracy. To prevent such issues, a back pressure of 0.1 to 0.3 Bar must be added at the outlet of the metering pump. Installing a back pressure valve in the outlet pipeline of the metering pump can achieve this. Pulsation dampeners utilize the compressibility of gas to cushion fluid pulsations in pipeline transport.
A pulsation dampener is essentially a chamber that stores pressurized fluid, using the compressibility of gas to buffer the pulsations of incompressible fluids. Systems such as metering pumps, pneumatic pumps, plunger pumps, reciprocating pumps, dosing systems, and dry powder preparation and dosing systems require the installation of pulsation dampeners: PVC back pressure valves, PVC safety valves, metering pump diaphragms, PVC pulsation dampeners, and Y-strainers.
Y-strainer product structure and purpose: This strainer consists of a housing, drain cover, PVC back pressure valve, PVC safety valve, metering pump diaphragm, PVC pulsation dampener, Y-strainer screen, and other components. It is a device required for pipeline systems transporting media, serving to remove mechanical impurities from the medium and protect equipment and pipeline components from wear and clogging.
