Preventive Fluid Maintenance with the LMI SP-238 Rebuild Kit
Routine maintenance helps keep chemical metering pumps operating accurately and efficiently. Over time, O-rings, diaphragms, and check valves wear from constant exposure to water treatment chemicals. As a result, pumps can lose prime, develop leaks, or deliver inaccurate chemical doses. The LMI SP-238 Repair Kit provides a genuine replacement solution that restores the fluid end and helps reduce unexpected downtime.
The LMI SP-238 Uni-Dose Repair Kit is designed specifically for new-style Uni-Dose pumps equipped with the LE-238NU liquid end. Instead of purchasing individual replacement parts, you receive a complete maintenance kit with the most common wear components. Therefore, technicians can complete preventive maintenance faster while keeping chemical feed systems operating at peak performance.
The kit includes durable Polyprel O-rings, a genuine SC3 Fluorofilm Liquifram® diaphragm, and replacement suction, discharge, and injection check valve cartridges. Together, these components restore proper sealing, improve chemical dosing accuracy, and help extend pump service life. In addition, the high-quality materials provide excellent resistance to chlorine and many common water treatment chemicals.
The preassembled check valve cartridges simplify installation and reduce maintenance time. Furthermore, they help eliminate assembly errors during field service and restore reliable pump operation. Whether you perform scheduled maintenance or rebuild a worn fluid end, this genuine LMI SP-238 Rebuild Kit helps maintain accurate and dependable chemical delivery.
Available from Water Treatment Supply, the LMI SP-238 Repair Kit helps protect chemical feed equipment and supports long-term pump performance. Consequently, it reduces maintenance costs, minimizes downtime, and keeps compatible LMI Uni-Dose chemical metering pumps operating with confidence.

FAQs
- How do I know if the LMI SP-238 repair kit fits my specific dosing pump?
This repair kit is designed specifically for new-style LMI UniDose series pumps fitted with the LE-238NU liquid end assembly. Please check your pump’s data plate before ordering to ensure correct fitment. - What materials are used to make the o-rings in this LMI SP-238 UniDose repair kit?
The primary high-wear o-rings are moulded from Polyprel, a specialised LMI fluoroelastomer compound that provides excellent resilience against standard water treatment chemicals, balancing fluids, and pool treatments. - Does this UniDose replacement kit include pre-assembled check valves?
Yes. To make installation quick and straightforward, this LMI SP-238 rebuild kit features three suction cartridge assemblies, one discharge cartridge assembly, and one injection cartridge assembly. These pre-seated components eliminate the hassle of rebuilding internal valve seats in the field. - What is a “Liquifram” and what role does it play in this metering pump repair kit?
The Liquifram is LMI’s advanced composite diaphragm, manufactured with an SC3 Fluorofilm face. It acts as a rugged, flexible barrier that separates the pump’s inner mechanical drive from the chemical fluid head, delivering highly repeatable volumetric accuracy. - Why should I choose genuine LMI replacement parts SP-238 over generic alternatives?
Genuine LMI components are built to precise factory dimensions and material standards. Choosing original parts prevents chemical leaks, guarantees a perfect fit within your liquid end, and preserves your chemical metering pump‘s overall performance profile.
