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.

Threaded dry-rotor in-line circulator pump for heating, cooling and DHW

The DAB ALM and ALP is a dry-rotor in-line pump with threaded ports: 180 mm with 1½" threads or 250 mm with 2" threads. It moves water in heating, cooling or domestic hot water return systems in residential and industrial installations, with up to 21 m head and 8.4 m³ per hour. At Q-Tech we fit it in pre-assembled plant rooms.

What is the DAB ALM and ALP?

It is a DAB in-line electric pump with an asynchronous motor kept apart from the water (dry rotor) and a silicon carbide mechanical seal. The ALM has a four-pole motor (1,400 rpm) and the ALP a two-pole motor (2,800 rpm). The ALM 200 and ALP 800 have a bronze body and motor bracket; the ALM 500 and ALP 2000 are cast iron.

What problem does it solve?

Some systems run very hot water or keep the pump running for long hours, and a wet-rotor circulator is not the best choice.

The ALM and ALP handles liquids from −15 to +120 °C, with threaded ports so it fits without flanges. The bronze versions are suited to domestic hot water return. It is a fixed-speed pump: it does not regulate flow by itself.

  • For domestic hot water, choose the bronze-bodied models (ALM 200 and ALP 800).
  • Mount only with the motor shaft horizontal.
  • Three-phase models need a motor protection switch in the panel, as regulations require.

Frequently asked questions

ALM or ALP?

The ALM turns slower (four-pole) and gives low head; the ALP (two-pole) gives more head in the same pump size.

Can it be used for domestic hot water?

Yes, the ALM 200 and ALP 800, which have a bronze body. The 500 and 2000 are cast iron.

Are the unions included?

No. Unions are sold separately.

What is the delivery time?

It is in stock at our warehouse; if none were left, we would order it urgently and tell you the lead time.

Who should install it?

Qualified professionals must make the plumbing and electrical connections.

Q-Tech installation and support

Q-Tech fits and tests the pump in our workshop as part of a pre-assembled plant room, which arrives tested and ready to connect. To replace a pump in your system, book an on-site Expert Technician by the hour; if you are unsure which model fits, request a technical call. More equipment in DAB circulator pumps.
