LMI Milton Roy 10322 Ceramic Weight - Maintain Vertical Stability for Optimal Chemical Flow, Fits 1/4", 3/8", 1/2" Tubing, Chemical Resistant

LMI 10322 Chemical Suction Line Ceramic Weight

The LMI Milton Roy 10322 Ceramic Weight is a durable, chemical-resistant stabilizer designed to keep chemical suction lines and foot valves properly positioned for accurate, uninterrupted dosing. Although branded by LMI, this ceramic weight is universally compatible with any brand of foot valve or strainer used on 1/4", 3/8", or 1/2" OD chemical suction tubing.

Constructed from high-density ceramic, the weight slides directly over vinyl, LDPE, or similar chemical feed tubing to maintain the foot valve in a vertical, fully submerged orientation. This prevents tubing curl, line float, or shifting inside chemical tanks—common issues that can cause loss of prime, irregular flow, or air ingestion in metering pumps.

The 10322 weight is chemically compatible with nearly all water treatment chemicals—except fluoride—making it a reliable accessory for municipal water plants, wastewater facilities, industrial process systems, cooling towers, and chemical feed skids.

By ensuring stable suction line placement, the LMI 10322 Ceramic Weight helps maintain consistent pump performance, accurate dosing, and trouble-free operation across a wide range of treatment applications.

Frequently Asked Questions (FAQs)

Is the LMI 10322 Ceramic Weight compatible with other brands of foot valves?

Yes. Even though it carries the LMI brand name, this ceramic weight works with any manufacturer’s foot valve as long as the tubing size is 1/4", 3/8", or 1/2" OD.

What does this ceramic weight do?

It keeps the chemical suction line and foot valve vertical and fully submerged, preventing the tubing from curling or floating, which can cause loss of prime or inconsistent chemical feed.

What tubing materials does it fit?

The weight slides over:

• Vinyl chemical feed tubing

• LDPE (low-density polyethylene) tubing

• Flexible chemical suction lines commonly used on metering pumps

Which chemicals is the weight compatible with?

It is compatible with most water treatment chemicals, including chlorine, bisulfite, caustic, acids, inhibitors, and polymers.
Exception: It is not compatible with fluoride solutions.

Will this weight work with 1/2" tubing?

Yes. It fits 1/4", 3/8", and 1/2" tubing. The internal diameter is designed to accept all three sizes.

Can the weight prevent air from entering the system?

Yes. Keeping the foot valve properly oriented and submerged reduces the risk of air entrainment, which can cause pulsation, lost prime, and dosing inconsistencies.

How is the weight installed?

Simply slide the ceramic weight over the suction line and position it above the foot valve. No tools are required.

Where is this weight typically used?

Common applications include:

• Municipal water treatment

• Wastewater plants

• Industrial process water

• Cooling towers

• Chemical feed skids

• Any system using metering pumps and a foot valve suction assembly

Is the ceramic material durable?

Yes. The ceramic is high-density, long-lasting, and corrosion-resistant, providing years of trouble-free service in harsh chemical environments.
