    Measure how high and far your system needs to move liquid. Then compare pumps by priming methods and flow control types.

    Compact Inline Circulation Pumps for Water

    Image of Product. Front orientation. Centrifugal Pumps. 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.

    Image of Product. Front orientation. Centrifugal Pumps. 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.

    High-Flow Inline Circulation Pumps for Water

    Image of Product. Front orientation. Centrifugal Pumps. 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.

    Easy-Maintenance Inline Circulation Pumps for Water

    Image of Product. Front orientation. Centrifugal Pumps. 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

    Image of Product. Front orientation. Centrifugal Pumps. 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.
