Metering pumps move precise volumes of liquid in a specified time period to provide accurate flow rates. This type of laboratory pump moves liquids in two stages: the suction stroke and the discharge stroke. During the suction stroke, liquid is pulled into the pump cavity past the inlet check valve. During the discharge stroke, the inlet valve closes; the outlet valve opens, and the liquid is pushed out. Ideal for water treatment, chemical processing, and laboratory dispensing. We have a variety of metering pumps to meet your exact application.
