Description
Genuine OEM Foot Valve Weight for LMI and Other Chemical Metering Pumps
The LMI Milton Roy 10322 Ceramic Weight is a genuine OEM chemical-resistant stabilizer that slides directly over your suction tubing and sits just above the foot valve. Its high-density ceramic construction holds the foot valve vertical and fully submerged, even as the chemical level in the tank drops, keeping your metering pump primed and dosing consistently.
As a genuine OEM LMI-branded part, the 10322 fits any standard chemical suction tubing in 1/4", 3/8", or 1/2" OD and works with foot valves and strainers from LMI Milton Roy.
Why Ceramic?
Ceramic foot valve weights have three advantages over lead or steel weights commonly used in older systems:
- Chemically inert across nearly all water treatment chemicals, won't corrode, rust, or leach metal ions into your chemical stream
- Safe for potable water applications where lead weights are not permitted
- Higher density than plastic or PVC alternatives provides more weight per unit volume, fitting compactly into smaller chemical tanks and drums
Key Features of the Genuine OEM LMI Milton Roy 10322 Ceramic Weight
- Universal tubing fit: 1/4", 3/8", or 1/2" OD chemical suction tubing, vinyl, LDPE, PE, PVDF, PTFE, FEP, and Tygon® compatible
- Cross-brand compatibility: works with foot valves and strainers from any major metering pump manufacturer using standard tubing OD
- High-density alumina ceramic construction: chemically inert in most water treatment applications
- Chemical compatibility: sodium hypochlorite (chlorine), sodium bisulfite, sodium hydroxide (caustic), mineral acids, scale and corrosion inhibitors, polymers, and most other water treatment chemistries
- Maintains pump prime: keeps the foot valve vertical and submerged, preventing air entrainment, lost prime, and pulsation
- Tool-free installation: slides over the suction line and seats above the foot valve
- Potable water safe: ceramic construction contains no lead, appropriate for drinking water disinfection systems
Tubing & Foot Valve Compatibility
| Tubing OD | Tubing Material | LMI 10322 Fit |
|---|---|---|
| 1/4" OD tubing | Vinyl, LDPE, PE, PVDF, FEP, Tygon® | Yes — fits |
| 3/8" OD tubing | Vinyl, LDPE, PE, PVDF, FEP, Tygon® | Yes — fits |
| 1/2" OD tubing | Vinyl, LDPE, PE, PVDF, FEP, Tygon® | Yes — fits |
Chemical Compatibility Note: Not recommended for fluoride or hydrofluoric acid applications. For all other common water treatment chemistries including chlorine, caustic soda, mineral acids, scale inhibitors, and polymers the 10322 provides reliable long-term service.
Applications
The LMI 10322 ceramic weight is used in chemical feed and dosing systems across:
- Municipal water treatment and disinfection
- Wastewater treatment facilities
- Cooling tower chemical treatment
- Boiler water treatment
- Industrial process water and chemical injection
- Chemical dosing skids and packaged systems
- Any system using a metering pump with a foot valve suction assembly
Installation
No tools required:
- Slide the ceramic weight over your chemical suction tubing
- Position the weight just above the foot valve or strainer
- Lower the assembly into your chemical tank the weight holds the foot valve vertical and submerged
If you're replacing an old weight, simply remove the existing one before installing the 10322 ceramic weight.

Frequently Asked Questions
Will the LMI 10322 fit my non-LMI metering pump?
Yes. As a genuine OEM LMI-branded part, the 10322 is a slip-over ceramic weight that fits any chemical suction tubing in 1/4", 3/8", or 1/2" OD. It works with foot valves and strainers from Pulsafeeder, Pulsatron, ProMinent, Chem-Tech, Walchem, Grundfos, and any other metering pump brand using standard tubing sizes.
Is the ceramic weight compatible with sodium hypochlorite (chlorine)?
Yes. Ceramic is chemically inert in chlorine and sodium hypochlorite solutions and is widely used in municipal disinfection systems for this exact application.
Can I use this weight in a fluoride dosing system?
No. The ceramic is not recommended for fluoride or hydrofluoric acid applications. For fluoride feed systems, contact our team for an alternative weight option.
Why is my chemical metering pump losing prime?
The most common cause is a foot valve tilting out of vertical position as the suction tubing curls inside the tank, air gets drawn into the suction line, and the pump loses prime. A ceramic weight like the 10322 holds the foot valve vertical and submerged, eliminating this failure mode in most installations.
Why ceramic instead of a lead or stainless steel weight?
Ceramic is chemically inert across nearly all water treatment chemistries, won't corrode or rust, and won't leach metal ions into your chemical stream, a particular concern with lead weights in potable water applications. It's also denser than plastic or PVC weights of equivalent volume.
How is the weight installed?
Slide it over the suction tubing and position it just above the foot valve. No tools required.
