Back pressure valves, diaphragms, pulsation dampeners, Y-strainers
When metering pumps operate under low system pressure, over-delivery can occur with PVC back pressure valves, PVC safety valves, metering pump diaphragms, PVC pulsation dampeners, and Y-strainers, affecting metering accuracy. To prevent such issues, it is necessary to apply a back pressure of 0.1 to 0.3 Bar 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 buffer liquid pulsation in pipeline transport.
Essentially, a pulsation dampener is a chamber that stores pressurized fluid, using the compressibility of gas to buffer the pulsation of incompressible fluids. Systems requiring pulsation dampeners include metering pumps, pneumatic pumps, plunger pumps, reciprocating pumps, dosing systems, dry powder preparation and feeding systems, etc., involving 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, filter screen, etc. It is a device required for pipeline systems transporting media, designed to remove mechanical impurities from the medium to protect equipment and pipeline components from wear and clogging.
