Circulation Pump EXEC CPI 15-15 — domestic hot water (CWU) circulation pump, model CPI 15-15

EXEC CPI 15-15 is a circulation pump designed for domestic hot water (CWU) recirculation systems. The CPI 15-15 maintains continuous water movement in plumbing loops to preserve set temperatures, reduce waiting time for hot water at taps, and limit heat loss in distribution pipes. The pump is intended for installation in residential and light-commercial hot-water recirculation circuits where reliable, steady circulation is required.

Advantages

The CPI 15-15 delivers steady circulation with compact dimensions suitable for tight plant rooms and under-sink installations. It contributes to improved hot-water availability and energy efficiency by reducing heat loss in pipes and shortening the time and water wasted while waiting for hot water. The design supports straightforward hydraulic integration into existing recirculation loops and facilitates routine maintenance.

Suitable for

• Residential hot-water recirculation loops
• Light-commercial sanitary installations
• Under-sink or utility-room circulation modules
• Systems aiming to reduce wait time and water waste at taps

Key specifications

• Type: domestic hot water (CWU) circulation pump
• Application: continuous recirculation in potable hot-water distribution
• Mounting: in-line plumbing integration compatible with standard domestic piping
• Operation: designed for continuous or periodic circulation duty
• Size and form factor: compact footprint for installation in confined spaces
• Materials: components suitable for potable water systems

How to use

Install the CPI 15-15 in the hot-water return line of the CWU loop according to local plumbing codes and the pump manufacturer’s installation instructions. Ensure correct flow direction and sealing of all connections. Connect the electrical supply following applicable safety standards and the pump’s wiring diagram. Commission the system by checking for leaks, confirming correct rotation and flow, and adjusting any system valves or thermostatic controls to achieve the desired circulation schedule and temperature maintenance.

Usage recommendations

For reliable operation, use the pump in circuits with appropriate check valves and balancing valves to prevent backflow and ensure uniform circulation. Periodically inspect seals and electrical connections and follow a preventive maintenance schedule to remove debris and maintain performance. Match the pump selection to system hydraulic requirements to avoid excessive wear and energy consumption.
