Metering Pumps

A metering pump is a positive displacement device that can efficiently pump a wide range of fluid types including chemicals, acids, bases, corrosives, and viscous liquids. Metering pumps provide extreme accuracy and dependability when precise volumes of a liquid need to be pumped in a specified amount of time.
Pumping Solutions distributes both Neptune and LMI brand metering pumps. If you are unsure what type of metering pump is correct for your specific application, contact us, or call us at 800-603-0399 and we will answer your questions and direct you towards the metering pump that is ideal for unique specifications.

Metering Pump Applications

Metering pumps are utilized in a broad range of applications where the precision flow rate is of the utmost importance. That is why metering pumps continue to be the chosen style of pump for industrial applications throughout the world. This includes chemical treatment of water in boilers for use in cooling towers and for processing potable water. Metering pumps are also used for wastewater treatment, blending of liquids in food processing plants, to reduce frictional losses within gas and oil pipelines. Metering pump processing applications include:
  • Chemical
  • Water
  • Food
  • Oil
 

How Metering Pumps Work

Metering pumps effectively operate through numerous processes within the device. Each process allows the pump to efficiently move and accurately asses how much liquid is being moved within a specified amount of time. Metering pumps abide by the following operational steps:
 
  1. The metering pump’s hollow piston reciprocates within the cylinder. A metering rod with a reduced diameter “nose” fits into the piston. A liquid seal forms where the full diameter of the piston contacts the cylinder.
  2. As the piston moves forward, oil bypasses the metering rod’s reduced nose and move through the port to the center of the piston and back to the gearbox. As the piston continues forward, the port is blocked by the tip of the metering rod, which stops the oil bypass. The oil is now pushed through the port to the diaphragm.
  3. Adjusting the micrometer dial moves the metering rod, changing the metering pump’s capacity. When moved in, the tip of the metering rod closes the port sooner in the stroke, reducing oil bypass and creating more pumping action. Conversely, when the metering rod is moved out, its tip closes the port later in the stroke, permitting more bypass and reducing pumping action.
  4. Piston motion moves hydraulic fluid through the port, into and out of the diaphragm chamber. The action of the hydraulic fluid pushes and pulls the diaphragm, which pushes and pulls pumped fluids through the port. Check valves control the direction of liquid flow.

Metering Pump Options & Advantages

Due to their numerous beneficial qualities, metering pumps are widely used throughout many different types of industries. The pump’s leak detection capabilities, along with the double-diaphragm design allow metering pumps to run continuous operations without the threat of downtime. Metering pumps provide unmatched reliability and product longevity, with minimal maintenance.
