LMI metering pumps are precision positive-displacement pumps designed to accurately inject precise amounts of chemicals into fluid systems for water treatment, laboratory, chemical, life sciences, and industrial processes. Available in solenoid and motor-driven models, they offer dependable performance, precise control options, and resistance to corrosive and harsh chemicals using materials such as PVC, PVDF, and stainless steel. Overall, LMI pumps provide precise, dependable chemical dosing that improves process precision, safety, and efficiency.
The LMI brand has been a prominent name in the pump industries for a long time.
LMI metering pumps are able to precisely deliver controlled volumes of chemicals for accurate process results.
LMI manufactures metering pumps in different models available in electronic solenoid and motor-driven designs to suit different application needs.
LMI metering pumps are manufactured with materials such as PVDF, PVC, stainless steel, and Hastelloy. This gives them strong resistance to harsh and corrosive chemicals.
LMI metering pumps come with features such as LCD screens, and precise input selection allowing for accurate flow-proportional dosing.
With the versatility of LMI metering pumps they make a great pump option for food, beverage, chemical, industrial, laboratory and medical applications.
LMI Metering pumps are able to be used with acids, bases, viscous liquids, and slurries. Making them capable of being used in many different industries and applications.
LMI metering pumps are very energy efficient. This allows them to use less power and save on electricity costs.
LMI designs their metering pumps for long service life. This reduces maintenance and application downtime.
With LCD displays, simplified interfaces, and precise controls LMI metering pumps are very user friendly. Ensuring easy setup and adjustments.
LMI metering pumps have adjustable flow rates up to 600 LPH. This makes them perfect for small or large scale applications.
LMI offers warranties for their metering pumps. This means that they offer support if there is issues with their pumps.
LMI metering pumps are used to precisely dose chemicals and liquids across industries such as water and wastewater treatment, industrial processing, oil and gas, agriculture, food and beverage, power generation, and manufacturing. They accurately handle a wide range of chemicals—including acids, biocides, polymers, and high-viscosity fluids—for applications like disinfection, pH control, scale and corrosion inhibition, and flocculation. By delivering controlled, repeatable chemical injection, LMI pumps help improve process efficiency, system reliability, and operational safety.
LMI metering pumps are manufactured by Ingersoll Rand.
Choosing the right LMI metering pump starts with clearly defining your application requirements, including the chemical’s viscosity, corrosiveness, temperature, required flow rate, system pressure, and the level of dosing accuracy or control needed. These factors guide the selection of the appropriate LMI pump type—such as solenoid for general dosing, stepper-driven models for high precision, or peristaltic pumps for versatility and easy maintenance—along with compatible wetted materials like PVC, PVDF, or stainless steel. For best accuracy and long service life, the pump should be sized to operate between 10% and 90% of its maximum capacity and include the necessary control options, such as manual adjustment, 4–20 mA input, or pH/ORP control.
