The Kelco LM-H-25B is a heavy-duty side entry liquid level switch engineered for long service life in demanding applications. Built with a 316 stainless steel process connection, machined aluminium housing, and a glass-reinforced polypropylene float and arm, the LM Series delivers reliable and accurate tank level control for industrial, chemical, and water treatment environments.
This model features a 500V AC, 15A SPDT microswitch, suitable for all general control circuit applications, including direct pump motor control up to 0.5HP at 240V AC, or for use with contactors and relays for higher loads. A built-in manual override allows for easy testing, commissioning, and manual pump activation.
The LM Series utilises a seal-less magnetic drive to eliminate gland and seal wear, and its IP67-rated housing ensures dependable operation in wet or dusty environments. Available in both 1” BSP and 1” NPT process connections, with a low-voltage gold-contact option for PLC and telemetry applications.
