LMI Spare Parts Kit, U-Series

Keep an LMI U-Series chemical metering pump running smoothly and dosing accurately with this LMI spare parts kit, thoughtfully assembled to refresh the components that experience the most wear during normal day-to-day operation. Rather than tracking down individual seals, valves, and diaphragms from different sources when a pump starts to falter, technicians get all of the key service items together in one convenient, matched package that makes a wet-end rebuild quick and straightforward.

The kit contains one Liquifram diaphragm, four duckbill-style Uni-Valves, a seal, a spring, and a shaft seal. These are precisely the parts that flex, seal, compress, and cycle thousands upon thousands of times in a working metering pump, and over time they fatigue and wear. Replacing them proactively on a maintenance schedule restores accurate dosing, reliable prime, and leak-free operation, returning the pump to like-new performance. Refreshing these soft components before they fail outright is far easier, cheaper, and less disruptive than diagnosing and chasing down the cause of a pump that has quietly drifted out of specification and started under-dosing.

Chemical feed pumps are central to water disinfection and treatment, dosing chlorine, scale inhibitors, pH adjusters, and other chemicals with stroke-by-stroke precision that the entire treatment process depends on. Because their soft sealing parts naturally wear from constant cycling and chemical exposure, keeping a spare kit like this on the shelf means a service technician can rebuild the wet end quickly and get the system back online with minimal downtime. Always follow the pump's service manual for the correct disassembly steps, the proper orientation of each part, and the reassembly sequence when performing the rebuild for best results. Establishing a regular rebuild interval based on the pump's run time and the chemical being fed is the surest way to avoid surprise failures, and because this kit gathers every essential soft part into one package, a technician can plan that maintenance with confidence rather than scrambling to source individual components after a problem has already disrupted the treatment process.
