“Y” type strainers are device which are used for mechanically removing solids from flowing liquids or gases by means of a perforated or wire mesh straining elements.
Pulsation is another problem that is typical with most metering pumps and in some cases cannot be tolerated by the application.
Pressure relief valve is a self operating valve that is used to relieve pressure by allowing the pressurized fluids (liquids. Gas or gas liquid mixtures) to flow from an auxiliary passage out of the vessel or process system.
Many metering pump applications dispense to atmospheric conditions or into a process with less than 1.5 bar pressure and more typically, into a process with erratic system pressure.
