Strainer, Foot Valve

This polypropylene foot valve strainer is a genuine replacement part for LMI chemical metering pump systems, mounting at the end of the suction tubing where the pump draws chemical from the supply tank. It performs two essential jobs at once. First, it screens out particulate matter and debris that could otherwise clog the pump head or foul the delicate check valves. Second, as a foot valve it helps keep the suction line primed, ensuring the pump can pull chemical reliably and inject an accurate dose on every single stroke.

In chemical feed applications, even small bits of debris or a momentary loss of prime can seriously disrupt dosing, leading to under-feeding, over-feeding, or a complete loss of injection. That makes a clean, properly functioning foot valve strainer essential to consistent, accurate chemical delivery. The polypropylene construction is chosen for its resistance to a wide range of treatment chemicals, making this strainer suitable for the solutions most commonly metered in water treatment, including sodium hypochlorite for chlorination, soda ash for pH adjustment, and various scale and corrosion inhibitors.

• Foot valve strainer for LMI chemical feed pump systems
• Durable polypropylene construction for broad chemical resistance
• Screens particulate to protect pump internals and check valves
• Helps maintain suction-line prime for accurate, repeatable dosing
• Genuine LMI-brand replacement part
• Simple to install on the suction tubing in the chemical tank

Keeping a spare strainer on hand is smart practice that minimizes downtime when the original eventually becomes clogged with sediment or worn from chemical exposure. It is a small and inexpensive component, but it has an outsized effect on the metering reliability of the entire feed system, which is why experienced service technicians treat it as routine maintenance stock. Simply install it on the suction-side tubing inside the chemical supply tank, and inspect it periodically for buildup or deterioration to keep your chemical feed system dosing precisely and dependably. In applications where the chemical solution tends to settle, crystallize, or carry sediment, the strainer earns its keep many times over by stopping that material before it reaches the pump, and pairing routine strainer inspection with regular cleaning of the chemical tank itself goes a long way toward preventing the dosing interruptions that can otherwise compromise disinfection or treatment.
