The Grundfos COMFORT PM Recirculating Pump It is specifically designed to provide maximum comfort and efficiency in domestic hot water (DHW) systems in single-family and semi-detached homes. Its advanced technology guarantees instant hot water at the tap, while minimizing energy consumption.
This model represents the pinnacle of the Experience Grundfos' domestic recirculation system. It's an investment in lasting comfort, reliability, and energy savings.
The main technical advantage of the COMFORT PM Pump It is their exclusive Spherical MotorThis design feature increases reliability and reduces the need for maintenance:
Without Rotating Axis: Unlike conventional encapsulated motors, the spherical motor lacks a rotating bearing shaft. The magnetic field is transferred directly to the rotor that propels the water.
Hermetic Separation: The part of the pump that drives the water is hermetically sealed from the stator by a spherical stainless steel separator. This effectively prevents sediment from entering.
Simplified Maintenance: The motor can be easily removed from the pump housing. This allows for quick cleaning, maintenance, or replacement without having to disassemble the system's hydraulics.
| Key Benefit | Strategic Value |
| Instant Hot Water | Efficient DHW recirculation that eliminates waiting, improving daily comfort. |
| Approved Materials for Drinking Water | Internal components and bronze housing fully approved for use with potable water (DWGW). Maximum Trust and hygiene. |
| Maximum Durability | Corrosion-resistant impeller made with high-quality materials (stainless steel, EPDM, PPO, PTFE and graphite). |
| Low Consumption | Permanent Magnet (PM) motor that guarantees superior energy efficiency compared to standard pumps. |
Application Note: This pump is designed to be used exclusively in pressurized hot water systems.
Application Type: Domestic Hot Water (DHW) Recirculation in homes.
Engine Technology: Permanent Magnet Spherical Motor (PM).
Pump Housing Material: Bronze (approved for drinking water).
Impeller Material: Stainless steel, EPDM, PPO, PTFE, Graphite.
Maintenance: Removable motor head for quick maintenance.
Control Technology: Simple version (not automatic/AUTOADAPT).
Although this is the basic version, it is worth noting that the COMFORT range offers the exclusive function in its automatic versions. AUTOADAPT.This function guarantees minimum energy consumption and maximum comfort by learning the hot water consumption patterns of the home. (See the automatic versions for this functionality).
The use of bronze in the housing is crucial to ensure compatibility with potable water and prevent long-term corrosion. This material meets the strictest sanitary regulations.
The spherical motor is more reliable and quieter because it eliminates the rotating shaft and mechanical seals, which are common points of wear and leakage in conventional motors. Its hermetically sealed design reduces the risk of blockages from dirt or sediment.
No. The Grundfos COMFORT PM Circulating Pump has been designed and should only be used in pressurized domestic hot water systems.
