About Metering Pumps

Metering pumps are positive displacement chemical dosing devices with the ability to vary capacity manually or automatically, as process conditions require. Metering pumps feature a high level of repetitive accuracy and are capable of pumping a wide range of chemicals including acids, bases, corrosives, or viscous liquids and slurries. Metering pumps are usually driven by a constant speed AC motor, although different drive mechanisms may be used depending upon the application at hand including fixed speed, variable speed, electric drive, solenoid drive, and magnetic drive. The drive mechanism translates the rotary motion of the driver into reciprocating movement. Industrial duty metering pumps will submerge this portion of the pump in an oil bath to assure reliability during continuous operation.

Products & Services Related to Metering Pumps

Booster Pumps

Booster pumps are used in applications where the normal system pressure is low and needs to be increased.

Condensate Pumps

Condensate pumps are used to collect and transport condensate back into a steam system for reheating and reuse, or to remove unwanted condensate from an HVAC or appliance collection pan.

Diaphragm Pumps

Diaphragm pumps use a diaphragm that moves back and forth to transport liquids from one place to another.

Drum Pumps

Drum pumps are used to transfer materials from a container into a process or other container. They may be electrically, hydraulically, or pneumatically powered depending on the working environment or application.

Gear Pumps

Gear pumps use intermeshing gears to pump various types of liquids. Typically, one gear is the driver and the other is free wheeling. The gears have very tight tolerances so that the fluid being pumped cannot pass through them. Common uses for gear pumps include high pressure, metering, and flow control applications.

Industrial Liquid Handling Pumps

Industrial liquid handling pumps are classified in many different ways, and are distinguished by the media pumped and the fluid motive mechanism (dynamic or displacement).

Screw Pumps

Screw pumps are rotary, positive displacement pumps that have one or more screws to transfer fluids or materials along an axis.
