At Q-TECH, we apply the same clear rules for everyone: the law protects you, and when applied correctly, it protects us as well. By processing your purchase, you accept our General Terms and Conditions of Sale. If you are purchasing as a consumer (B2C), nothing stated herein limits the rights granted to you by mandatory law (RDL 1/2007, TRLGDCU): the 3-year legal warranty of conformity and the right of withdrawal under the terms and with the exceptions legally provided, which are detailed below. References to "B2B" apply only to businesses and professionals.

Your guarantees

  • Rights intact: 14 days of withdrawal from receipt for most products—subject to the legal exceptions you will see below, such as goods made to your specifications—and a 3-year legal warranty of conformity, under the terms of the TRLGDCU.
  • Conformity with the description: we guarantee that the equipment will correspond to the published technical description and what one could reasonably expect from it (arts. 115 et seq. TRLGDCU). Images and videos are for guidance only: the manufacturer may supply a more recent revision of the product or introduce minor aesthetic, packaging, or firmware changes, without this constituting a lack of conformity as long as the described characteristics and performance are maintained.
  • Traceability that also protects you: we document the condition, serial number, and seal of each piece of equipment upon shipment, and we video-record the opening of returns; this is your proof of the condition in which the goods were delivered.

Responsible use and your part

  • If you are thinking of returning it, keep it as you received it: without installing or activating it, with its seals, accessories, and packaging intact. This is how to ensure a full refund, without deductions.
  • Handling that exceeds inspection reduces value: handling the equipment beyond what is necessary to verify its nature and operation may result in a real, assessed, and case-by-case justified deduction (art. 108.2 TRLGDCU), never a fixed percentage. In particular: activating or registering the serial number, linking it to a manufacturer's account or app, circulating water through hydraulic equipment, unsealing probes, or installing software or consumables. Initial inspection of the product does not lead to a deduction.
  • The same item must be returned: withdrawal requires returning the supplied unit. Different equipment, or equipment with prior use, age, or wear prior to purchase, does not constitute a valid withdrawal.
  • Installation and cybersecurity, shared responsibility: this is technical hardware; you are responsible for correct installation, credentials, patches, and backups, while we deliver a compliant product. Q-TECH is not liable for damages resulting from poor installation, incorrect configuration, or omission of patches by the customer or third parties (in B2C, without prejudice to the legal warranty and liability for intent or negligence, arts. 86 and 130 TRLGDCU).
  • Delivery of bulky goods: delivery is made to the curb. B2C: transport risk is ours until physical delivery (art. 66 ter); we recommend noting visible damages on the delivery note and notifying us of breakages within 24-48 hours with photographs to activate the insurance. B2B: inspection and notation on the delivery note are mandatory; hidden damages must be reported within 24 hours (art. 366 CCom). Unjustified rejection or incorrect shipping information will entail the actual outbound and return costs (approx. €85-550 for heavy machinery).

Made to your measure (Advanced Pre-Assembly)

  • If your order includes equipment, racks, hydraulic assemblies, or technical rooms made or configured according to your specifications (permanent joints, custom cuts or wiring, parameterization, pressure testing), these are custom goods without the right of withdrawal from the conclusion of the contract (art. 103.c TRLGDCU; CJEU Case C-529/19), which is informed before purchasing and documented in the signed Order Note. A test you request without permanent modification retains your right of withdrawal, with only the actual loss of value caused by that test being deducted. Would you prefer to receive it tested, configured, and ready to connect, without assuming these risks? Contract our Advanced Pre-Assembly or the prior technical audit.

If you are purchasing as a business or professional (B2B)

  • The transaction is governed by the Commercial Code: firm sale, without the right of withdrawal; notification of defects within 4 days (apparent) / 30 days (hidden), arts. 336 and 342. Q-TECH acts as a distributor and excludes indirect damages, loss of profit, and data loss, limited to the price of the equipment, without prejudice to the manufacturer's commercial warranty.

The Grundfos Spherical Motor Technology DHW Recirculation Solution

The Grundfos COMFORT PM Recirculator Pump is specifically designed to provide maximum comfort and efficiency in Domestic Hot Water (DHW) systems for detached and terraced homes. Its advanced technology ensures instant hot water at the tap, while reducing energy consumption to a minimum.

This model represents the pinnacle of Grundfos Experience in domestic recirculation. It is an investment in lasting comfort, reliability, and energy savings.

🔬 Spherical Technology: Silent and Reliable Operation

The main technical advantage of the COMFORT PM Pump is its exclusive Spherical Motor. This design feature increases reliability and reduces maintenance needs:

  • No Rotating Shaft: Unlike conventional canned motors, the spherical motor lacks a rotating bearing shaft. The magnetic field is transferred directly to the rotor that drives the water.

  • Hermetic Separation: The part of the pump that drives the water is hermetically separated from the stator by a stainless steel spherical separator element. This effectively prevents the ingress of sediments.

  • 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 hydraulics.

✅ Key Benefits for the User and the Installation

Key Benefit Strategic Value
Instant Hot Water Efficient DHW recirculation that eliminates wait times, improving daily comfort.
Materials Approved for Potable Water Internal components and bronze housing fully certified for use with potable water (DWGW). Maximum Confidence and hygiene.
Maximum Durability Corrosion-resistant impeller made of high-quality materials (stainless steel, EPDM, PPO, PTFE, and Graphite).
Low Consumption Permanent Magnet (PM) motor that ensures superior energy efficiency compared to standard pumps.

Application Note: This pump is designed to be used exclusively in pressurized hot water systems.

🛠️ Technical Specifications

  • Application Type: Domestic Hot Water (DHW) recirculation in homes.

  • Motor Technology: Permanent Magnet (PM) Spherical Motor.

  • Pump Housing Material: Bronze (approved for potable water).

  • Impeller Material: Stainless steel, EPDM, PPO, PTFE, Graphite.

  • Maintenance: Removable motor head for quick maintenance.

  • Control Technology: Simple version (non-automatic/AUTOADAPT).

💡 About the AUTOADAPT Function (Automatic Versions Only)

Although this is the simple version, it is worth noting that the COMFORT range offers the exclusive AUTOADAPT function in its automatic versions. This function ensures minimum energy consumption and maximum comfort by learning the home's hot water usage patterns. (Consult the automatic versions for this functionality).

❓ Frequently Asked Questions (FAQ)

Why is it important that the pump housing is made of bronze?

The use of bronze in the housing is crucial to ensure compatibility with potable water (DHW) and prevent long-term corrosion. This material complies with the strictest health regulations.

What operational advantage does the spherical motor offer over a conventional canned motor?

The spherical motor is more reliable and quieter because it eliminates the rotating shaft and mechanical seals that are common points of wear and leakage in conventional motors. Its hermetic separation design reduces the risk of blockages due to dirt or sediments.

Can I install the COMFORT PM in low-pressure systems?

No. The Grundfos COMFORT PM circulator pump has been designed for and must only be used in pressurized domestic hot water systems.
