LMI's diaphragm back pressure/anti-syphon valves apply positive discharge pressure to a metering pump system and act to stabilize the output of higher output LMI Metering Pumps when pumping into low or no-pressure systems. Pressure relief valves are designed to protect chemical feed systems from overpressure damage caused by defective equipment or deadheading. Valves are available in 1/4", 1/2", and 1" sizes in PP, PVC, PVDF and 316SS.

Digi-Pulse Flow Monitors solve the age-old question, How do I know if my pump is pumping?
This innovative product is designed to be used with our Type 9 Series Metering Pumps to provide the user with verification of pump performance.If the Flow Monitor detects output loss, it will shut the pump off and close a switch that may be tied to an alarm. The alarm signal may also be used to trigger a stand-by pump.
