Smart Chemical Metering with the TD Series
In modern chemical dosing systems, accuracy, connectivity, and safety are essential for reliable operations. From adapting to changing flow requirements to enabling real-time monitoring and preventing hazardous leaks, advanced metering technology plays a critical role.
The LMI TD Series Chemical Metering Pumps combine wide turndown capability, seamless SCADA integration, and intelligent leak detection to deliver a flexible and secure dosing solution. Together, these features empower operators to maintain precise control, optimize efficiency, and protect both personnel and equipment across a wide range of industrial applications.

Understanding NEMA Enclosures & Environmental Protection
LMI’s TD Series pumps are engineered with superior protection in mind. Instead of relying solely on NEMA 4X terminology, these pumps are equipped with robust electrical enclosures that meet or exceed NEMA 3R and NEMA 12 specifications. These standards ensure the equipment remains fully operational in the face of windblown dust, rain, sleet, splashing water, temperature variation and the formation of ice. Let's explore why the TD Series pumps are ideal for protecting critical systems and how their design safeguards your investment.

Leak Detection Sensors in Chemical Metering Pumps
LMI TD Series are engineered with smart technology, including chemical leak sensors with automatic alarms and control system integration for rapid response to failures.
