Adjustable-Flow Inline Circulation Pumps for Water

Accommodate performance changes in your system with a three-speed switch that adjusts flow rate. Install these pumps directly in your pipeline for applications such as hot-water circulation and hydronic heating and cooling. They have an open dripproof (ODP) motor for use in clean, dry, and well-ventilated environments. Mount horizontally with the included pipe connectors. 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.

304 Stainless Steel Housing—Pumps with 304 stainless steel housing are lead free.

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. 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.

Easy-Maintenance Inline Circulation Pumps for Water

A detachable motor assembly allows you to leave these pumps inline while servicing or repairing the motor. The motor is open dripproof (ODP) for use in clean, dry, and well-ventilated environments. Install these pumps directly in your pipeline for applications such as hot-water circulation and hydronic heating and cooling. Mount horizontally or vertically with the included pipe connectors. 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.

Required Pipe Connectors—When ordering the required pipe connectors (sold separately), please specify pipe size of ¾, 1, 1 ¼, or 1 ½.
