LMI PUMPS

LMI PUMPS, a brand of Milton Roy (part of the Dover Corporation), is a manufacturer of chemical metering pumps and related accessories. The brand is known for its compact solenoid-driven diaphragm metering pumps, which are used for precise chemical injection in water treatment, industrial processing, and other fluid-handling applications. LMI PUMPS products are designed for reliable, repeatable dosing of chemicals such as chlorine, acids, caustics, and polymers. The pumps feature PTFE diaphragms, which provide chemical resistance and long service life, and are available with a variety of wetted-end materials including PVC, PVDF, polypropylene, acrylic, and 316 stainless steel to suit different chemical compatibility requirements. Reproducibility is typically specified at ±1.0% or ±3.0%, depending on the model, indicating consistent dosing accuracy. The pumps operate on standard AC voltages (115V or 115/230V) and are solenoid-driven, making them suitable for applications where precise, intermittent dosing is needed. LMI PUMPS also offers a range of accessories such as calibration columns, injection valves, and spare parts kits. 3G Electric supplies LMI PUMPS metering pumps and replacement parts, including service kits and repair components, to support maintenance and replacement needs for industrial and municipal customers globally. The product line covers multiple series (e.g., B, C, P, PD) with varying flow rates and pressure ratings, allowing selection based on specific process requirements. The pumps are typically rated for continuous duty and are designed for easy installation and maintenance. LMI PUMPS products are used in applications such as boiler water treatment, cooling tower chemical feed, wastewater disinfection, and industrial process chemical dosing. The brand's focus on solenoid-driven diaphragm technology provides a compact footprint and low power consumption compared to motor-driven pumps, making them suitable for panel-mounted or skid-mounted systems. 3G Electric stocks a range of LMI PUMPS models and parts to support ongoing operations and emergency replacements.

Pertanyaan yang Sering Diajukan

Pertanyaan umum tentang LMI PUMPS dari 3G Electric.

What types of chemicals can LMI PUMPS solenoid-driven diaphragm metering pumps handle?

LMI PUMPS metering pumps are designed for a wide range of chemicals, including chlorine, acids, caustics, polymers, and other water treatment chemicals. The wetted-end materials—such as PVC, PVDF, polypropylene, acrylic, and 316 stainless steel—are selected based on chemical compatibility. The PTFE diaphragm provides broad chemical resistance. Always verify compatibility with the specific chemical concentration and temperature using the manufacturer's chemical resistance guide.

What is the reproducibility specification on LMI PUMPS metering pumps?

Reproducibility for LMI PUMPS solenoid-driven diaphragm metering pumps is typically ±1.0% or ±3.0%, depending on the model. This specification indicates the pump's ability to deliver consistent dosing volume over repeated cycles under stable conditions. For example, models in the B and C series often have ±1.0% reproducibility, while some PD series models have ±3.0%. This accuracy is suitable for precise chemical feed in water treatment and industrial processes.

What voltage options are available for LMI PUMPS metering pumps?

LMI PUMPS metering pumps are available in 115V AC and 115/230V AC dual-voltage configurations. The specific voltage is indicated on the nameplate. For example, models like the B111-498NI operate on 115V AC, while the PD051-937NP operates on 115/230V AC. Ensure the pump is wired according to the supplied voltage to avoid damage. 3G Electric stocks both voltage variants to accommodate different facility electrical systems.

What wetted-end materials are available for LMI PUMPS metering pumps?

LMI PUMPS offers wetted-end materials including PVC, PVDF, polypropylene (PP), acrylic, and 316 stainless steel. The head material, diaphragm (PTFE), seals, and check balls are selected based on the model. For instance, the B111-498NI has a PVC head and PVDF fittings, while the PD051-937NP has a 316 SS head and fittings. Material selection depends on chemical compatibility and application requirements. 3G Electric provides pumps with various material combinations.

How do I select the correct LMI PUMPS model for my application?

Selection depends on required flow rate, pressure, chemical compatibility, and power supply. LMI PUMPS models are categorized by series (e.g., B, C, P, PD) with different flow ranges and pressure ratings. For example, the B111 series typically offers lower flow rates, while the PD series provides higher capacity. Check the pump's maximum flow rate (e.g., 168 gpd for B741-415SI) and pressure rating. Also, verify wetted-end material compatibility with the chemical. 3G Electric can assist with model selection based on your specifications.

Are replacement parts and service kits available for LMI PUMPS metering pumps?

Yes, 3G Electric supplies LMI PUMPS replacement parts and service kits, including diaphragms, check valves, seals, and complete repair kits. These parts are designed to restore pump performance and extend service life. For example, service kits include PTFE diaphragms and seal assemblies. It is recommended to use genuine LMI PUMPS parts to maintain reproducibility and reliability. Contact 3G Electric for specific part numbers and availability.
