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.

Pressure tank with a replaceable membrane for booster pump sets, from 24 to 700 litres

The Ibaiondo AMR pressure tank holds pressurised water next to your pump or booster set. Ibaiondo makes it in Spain and you will find it here from 24 to 700 litres, with one 24-litre model in stainless steel. At Q-Tech we fit it into your pre-assembled plant room, connected and tested with the pumps before it reaches site.

What is the Ibaiondo AMR?

The Ibaiondo AMR is a pressure tank for drinking-water booster pump sets that has a replaceable membrane. The membrane separates the water from a pre-charged air chamber. The 24-litre models have no legs and the AMR-B160 models stand on the floor on their legs.

What problem does it solve?

Without a reserve of pressurised water, the pump starts every time someone opens a tap. Ibaiondo explains that the tank keeps that reserve and secures the supply. The result is fewer pump starts, a longer life for the booster set and an energy saving, according to the manufacturer.

When the membrane of a fixed-membrane tank fails, the whole tank is replaced. On the Ibaiondo AMR you replace the membrane only. Ibaiondo states that the volume is sized to the Spanish standard UNE 149202 and the building code CTE DB HS4.

Compatibility and limits

  • The Ibaiondo AMR has a membrane suitable for drinking water, to EN 13831.
  • The maximum pressure depends on the model: 8 or 10 bar.
  • The working temperature is −10 °C to +70 °C, and the system maximum is 100 °C.
  • For domestic hot water, Ibaiondo refers to its CMR series.
  • The Ibaiondo manual states that it is not suitable for hydrocarbons.
  • The manual asks you to avoid direct radiation on the tank and to keep the valve and the label accessible.
  • The installation needs a safety device that limits the pressure below the maximum of the tank.

Frequently asked questions

Which Ibaiondo AMR model do I need?

It depends on the flow rate, the number of pumps and the start and stop pressures. Ibaiondo publishes a volume calculator for pressure tanks (in Spanish) and asks for the calculation to be done by authorised personnel.

What is the delivery time?

It is in stock at our warehouse. If no units are available when you order, we order it urgently and tell you the updated delivery time.

What is the difference between the 24 AMR-E and the 24 AMR-E Inox?

The tank material. The 24 AMR-E Inox is shot-blasted AISI 304 stainless steel, with a stainless steel connection. Capacity and maximum pressure are the same.

Can the membrane be replaced?

Yes. You will find those for the 24 AMR-E and for the 500 and 700 AMR-B160 under replacement membranes for Ibaiondo AMR. The 300 AMR-B160 takes a different part number: ask us.

How is the pre-charge set?

It arrives with 1.5 bar of air. The Ibaiondo manual says to set it, on the discharge side, to the pump start pressure minus 0.2 bar, and to check it at least once a year.

Can I install it myself?

That is not what the manufacturer states. Ibaiondo asks for it to be installed by professional installers or authorised technical staff.

Q-Tech installation and support

A pressure tank only does its job when its pre-charge is set to the start pressure of your pump. Q-Tech delivers it inside a pre-assembled plant room: assembled, wired and tested at our workshop, arriving on site ready to connect. You book it with the Expert Technician workshop pre-assembly service.

If your installation already exists, an on-site hourly Expert Technician connects the Ibaiondo AMR and sets its pre-charge. For selection questions there is the technical call. You can see the whole range under pressure tanks and Ibaiondo expansion vessels, or write to us on WhatsApp or through contact.
