What are LMI Pumps?

LMI pumps are chemical metering pumps manufactured by Milton Roy, a global leader in water treatment solutions. These pumps are engineered to provide precise dosing of chemicals such as chlorine, bromine or pH adjusters into swimming pools and spas. The result is consistently clean and balanced water that meets health and safety standards.

The key advantages of LMI pump systems include:

  • Accurate and repeatable dosing, ensuring chemicals are used efficiently.
  • Simple controls and user-friendly design, ideal for facility managers.
  • Robust construction that withstands the demands of continuous pool operation.
  • Compatibility with automation systems, reducing manual intervention.

Why Choose LMI Pumps for Spa and Leisure Facilities?

Spa and leisure facilities face constant pressure to maintain water quality that is both safe and pleasant for users. LMI pumps help achieve this by delivering precise control over chemical levels. This protects bathers from irritations caused by imbalanced water while extending the lifespan of pool equipment.

An LMI pool pump is especially suited for:

  • Commercial swimming pools where large volumes of water need consistent dosing.
  • Spa pools and hot tubs that require precise control to manage higher temperatures.
  • Hotel and leisure centres looking for reliable, low-maintenance systems.

By choosing an LMI pump, facility managers can focus on guest experience while knowing their water treatment system is running efficiently.

Types of LMI Pump Systems

There are several models of LMI pumps available, each designed for specific applications:

  • Electromagnetic dosing pumps – Compact and energy efficient, ideal for smaller pools or spa systems.
    Mechanically actuated diaphragm pumps – Durable and reliable, suitable for high-capacity dosing.
    Electronic metering pumps – Featuring digital controls for precision dosing and easy monitoring.
