Compact Inline Circulation Pumps for Water
Use these pumps in pipelines with limited clearance. Install directly in your pipeline for applications such as hot-water circulation and hydronic heating and cooling. Pumps mount horizontally or vertically with required pipe connectors. The motor cannot face downward; it’s cooled by the water being pumped. Do not run dry or use with solids.
Note: If flow control is needed, place valves or reducers on the discharge side; never restrict the inlet of a pump with a valve or reducer.

Extended-Life Inline Circulation Pumps for Water
Eliminate seal wear and leakage—these pumps have magnets that turn the impeller for a long service life. Install them directly in your pipeline for applications such as hot-water circulation and hydronic heating and cooling. Mount vertically or horizontally; the electrical conduit box must be placed on the bottom. Do not run dry or use with solids.
Note: If flow control is needed, place valves or reducers on the discharge side; never restrict the inlet of a pump with a valve or reducer.

High-Flow Extended-Life Inline Circulation Pumps for Water
These pumps have higher flow rate than other inline circulation pumps and are cooled by the liquid being pumped to extend the life of the motor. Install them directly in your pipeline for applications such as hot-water circulation and solar heating. Pumps have an open dripproof (ODP) motor for use in clean, dry, and well-ventilated environments. Mount horizontally with required pipe connectors (sold separately). Do not run dry or use with solids.
Note: If flow control is needed, place valves or reducers on the discharge side; never restrict the inlet of a pump with a valve or reducer.
To Order: For the required pipe connectors, please specify pipe size of 3/4, 1, 1 1/4, or 1 1/2.

High-Flow Inline Circulation Pumps for Water
A high-horsepower motor handles four times the flow and twice the pressure of other inline circulation pumps. Install these pumps directly in your pipeline for applications such as hot-water circulation and hydronic heating and cooling. Mount horizontally or vertically. The motor cannot face downward; it’s cooled by the water being pumped. Do not run dry or use with solids.
Note: If flow control is needed, place valves or reducers on the discharge side; never restrict the inlet of a pump with a valve or reducer.
Pumps that cannot be sold to California are restricted by local energy efficiency regulations.
